Введение ⇧

«Связный» код — это код, который сосредоточен на выполнении одной вещи, только одной единственной вещи. Это значит, что когда вы пишете функцию или метод — написанный вами код должен делать что-то одно и делать это хорошо.

Это непосредственно относится к написанию тестируемого кода: код, который делает много вещей, достаточно часто является чересчур сложным для тестирования. Когда я ловлю себя на мысли: «Хорошо, этот кусок кода слишком сложен, чтобы писать для него тесты — это просто не стоит потраченных усилий» — вот сигнал к тому, чтобы вернутся назад и сосредоточиться на упрощении. Тестируемый код — такой код, который позволяет просто писать для него тесты; код, в котором легко найти проблемы.

И наконец, мы хотим писать масштабируемый код. Это означает не просто масштабировать его в терминах исполнения, но так же увеличивать в терминах команды и командного понимания. Хорошо протестированные приложения проще для понимания другими (и проще для изменения ими), что подразумевает большую возможность улучшить ваше приложение, путем добавления новых инженеров.

Моя цель — убедить вас в важности этих принципов, и предоставить примеры того, как следуя им, построить более стойкое Django-приложение. Я собираюсь последовательно пройти через процесс построения приложения для управления контактами, рассказывая про решения и стратегию тестирования, которые я использую.

Эти документы являются сочетанием заметок и примеров подготовленных для PyCon 2012, PyOhio 2012, и PyCon 2013, а также для web-разработки Eventbrite. Я все еще работаю над объединением их в один документ, но надеюсь вы найдете их полезными.

Примеры кода для этого руководства доступны на github’е. Отзывы, предложения и вопросы можете присылать на nathan@yergler.net.

Глава 1. Приступая к работе ⇧

1.1. Ваша среда разработки

Изоляция означает, что вы не сможете случайно воспользоватся инструментами или пакетами установленными вне вашего окружения. Это особенно важно, когда подобное происходит с чем-то, похожим на пакеты Python с расширениями написанными на C: если вы используете что-то установленное на системном уровне и не знаете об этом, то при развертывании или распространении своего кода вы можете обнаружить, что он работает не так как предполагалось. Инструменты наподобие virtualenv могут помочь создать нечто похожее на изолированную среду.

Ваша среда предопределена, если вы уверены в том, на какую версию ваших зависимостей вы полагаетесь и сможете ли вы наверняка воспроизвести системное окружение.

1.1.1. Изоляция

• Мы хотим избежать использования неизвестных зависимостей или неизвестных версий. предоставляет простой путь для работы над проектом, без использования системных site-packages.

1.1.2. Предопределенность

• Предопределенность означает управление зависимостями.
• Выберете один из инструментов и используйте как при разработке, так на «боевом» сервере:
  и специальные файлы зависимостей; ; в setup.py .

1.1.3. Сходство

• Работа в среде, похожей на ту, где вы будете разворачивать ваше приложение и пытаться обнаружить проблемы.
• Если вы разрабатываете что-то, требующее дополнительных сервисов — сходство становится еще более важным. — это инструмент для управления виртуальными машинами, позволяющий вам легко создавать окружение отделенное от вашего повседневного окружения.

1.2. Настройка вашего окружения

1.2.1. Создание чистого рабочего пространства

Примечание переводчика:
Для начала создадим каталог ( tutorial ), в котором будем работать:

В каталоге venv будет находится наше виртуальное окружение, а в каталоге project — Django-проект

1.2.2. Создание файла зависимостей

Создайте файл requirements.txt в директории tutorial с единственной строкой (зависимостью) в нем:

1.2.3. Установка зависимостей

А теперь мы можем использовать pip для установки зависимостей:

1.3. Начало проекта Django

Когда здание находится в процессе постройки, строительные леса часто используются для поддержания структуры до того как строительство будет завершено. Строительные леса могут быть временными или они могут служить частью фундамента здания, но несмотря на это, они представляют некоторую поддержку когда вы только начинаете работу.

Django, как и многие web-фреймворки, представляет скаффолдинг для вашей разработки. Это происходит при помощи принятия решений и предоставления отправной точки для вашего кода, что позволяет вам сосредоточится на проблеме, которую вы пытаетесь решить, а не на том, как разобрать HTTP-запрос. Django предоставляет скаффолдинг как для работы с HTTP, так и для работы с файловой системой.

HTTP-скаффолдинг управляет, например, преобразованием HTTP-запроса в объект языка Python, а также предоставляет инструменты для более простого создания серверных ответов. Скаффолдинг файловой системы иной: это набор соглашений по организации вашего кода. Эти соглашения облегчают добавление новых инженеров в проект, так как инженеры (гипотетически) уже понимают как организован код. В терминах Django, проект — это конечный продукт, и он объединяет внутри себя одно или несколько приложений . В Django 1.4 было изменено то, как проекты и приложения размещаются на диске, что облегчило разъединение и повторное использование приложений в разных проектах.

1.3.1. Создание проекта

Django устанавливает в систему скрипт django-admin.py для обработки задач скаффолдинга. Для создания файлов проекта используется задача startproject . Мы определим имя проекта и имя директории, в которой хотим разместить проект. Так как, мы уже находимся в изолированной среде, можно просто написать:

/tutorial/project/ и в дальнейшем будем работать только из этой директории (под $ далее будем подразумевать

Созданный проект имеет следующую структуру

1.3.2. Скаффолдинг проекта

• manage.py — является ссылкой на скрипт django-admin , но с уже предустановленными переменными окружения, указывающими на ваш проект, как для чтения настроек оттуда, так и для управления им при необходимости;
• settings.py — здесь находятся настройки вашего проекта. Файл уже содержит несколько разумных настроек, но база данных не указана;
• urls.py — содержит URL’ы для маппирования (отображения) представлений: мы вскоре (в дальнейших главах) поговорим об этом подробнее;
• wsgi.py — это WSGIобёртка для вашего приложения. Этот файл используется сервером разработки Django и возможно другими контейнерами, такими как mod_wsgi , uwsgi и др. на «боевом» сервере.

1.3.3. Создание приложения

Созданное приложение имеет следующую структуру:

• Начиная с Django 1.4, приложения размещаются внутри пакета с проектом. Это замечательное улучшение, особенно когда приходит время разворачивать проект на «боевом» сервере;
• models.py будет содержать Django ORM-модели для вашего приложения;
• views.py будет содержать код представлений;
• tests.py будет содержать написанные вами модульные и интеграционные тесты.
• Django 1.7: admin.py будет содержать модель для административного интерфейса.
• Django 1.7: migrations/ содержит файлы миграций

/tutorial/ содержит файл зависимостей ( requirements.txt ), директорию с виртуальным окружением ( venv/ ), один проект ( project/addressbook ), одно приложение ( project/contacts ) и имеет следующее содержание:

Глава 2. Используем модель ⇧

2.1. Конфигурирование базы данных

Django поддерживает «из коробки» MySQL, PostgreSQL, SQLite3 и Oracle. SQLite3 входит в состав Python начиная с версии 2.5, так что мы будем использовать его в нашем проекте (для простоты). Если вы хотите, к примеру, использовать MySQL, то нужно добавить mysql-python в ваш requirements.txt .

Для того чтобы в качестве базы данных использовать SQLite, отредактируйте определение DATABASES в файле addressbook/settings.py . Файл settings.py содержит настройки Django для нашего проекта. В нем есть несколько настроек, которые вы обязаны указать — например DATABASES — а так же другие, необязательные, настройки. Django устанавливает некоторые настройки сам, когда генерирует проект. Документация содержит полный список настроек. К тому же вы можете добавить свои собственные настройки, если это необходимо.

Для использования SQLite нам нужно указать движок ( ENGINE ) и имя базы ( NAME ). SQLite интерпертирует имя базы как имя файла для базы данных:

Заметьте, что движок базы данных указан строкой, а не прямой ссылкой на объект Python. Это сделано по той причине, что файл настроек должен быть легко импортирован не вызывая сторонних эффектов . Вы должны избегать добавления вызовов import в этот файл.

Вам редко придется непосредственно импортировать файл настроек: Django импортирует его за вас, и делает настройки доступными как django.conf.settings . Вы, как правило, импортируете настройки из django.conf :

2.2. Создание модели

Модели Django отображают (грубо говоря) таблицы базы данных, и предоставляют место для инкапсулирования бизнес-логики. Все модели являются наследниками базового класса Model и содержат поля определений. Давайте создадим простую модель Contacts для нашего приложения в файле contacts/models.py :

Django предоставляет набор полей для отображения типов данных и различных правил валидации. К примеру, EmailField , который мы использовали, является отображением на колонку с типом CharField , но добавляет валидацию данных.

После того, как вы создали модель, необходимо дополнить вашу базу данных новыми таблицами. Команда Django syncdb смотрит установленные модели и создает (если нужно) таблицы для них:

Примечание переводчика:
Если вы используете Django версии 1.7 и выше — вывод будет следующий:

Однако нашей таблицы с контактами нигде не видно. Причина этого состоит в том, что нам нужно еще указать проекту использовать приложение.

Настройка INSTALLED_APPS содержит список приложений, используемых в проекте. Этот список содержит в себе строки, которые отображают пакеты Python. Django будет импортировать каждый из указанных пакетов, а потом смотреть модуль models . Давайте добавим наше приложение contacts в настройки проекта ( addressbook/settings.py ):

После этого запустите syncdb снова:

Примечание переводчика:
Вывод для Django 1.7 и выше:

Заметьте, что Django создает таблицу с именем contacts_contact : по умолчанию Dj ango дает таблицам имена используя комбинацию имени приложения и имени модели. Вы можете изменить это с помощью опций модели Meta.

2.3. Взаимодействие с моделью

Теперь, когда модель синхронизирована с базой данных мы можем взаимодействовать с нею используя интерактивную оболочку:

Здесь использовалось несколько новых штук. Во-первых, команда manage.py shell запускает для нас интерактивную оболочку Python’а с правильно установленными путями для Django. Если вы попробуете запустить интерпретатор Python и просто импортировать ваше приложения, будет выброшено исключение, потому что Django не знает, какие настройки использовать, и не может отобразить экземпляры модели на базу данных.

Во-вторых, здесь использовалось свойство objects нашей модели. Это менеджер модели. Так, если один экземпляр модели является аналогией для строки в базе, то менеджер модели — аналогией для таблицы. По умолчанию менеджер модели предоставляет функциональность запросов и может быть настроен. Когда мы вызываем all() , filter() или сам менеджер, возвращается объект QuerySet . QuerySet является итерируемым объектом и загружает данные из базы по необходимости.

И последнее — выше использовалось поле с именем id , которое мы не определяли в нашей модели. Django добавляет это поле как первичный ключ для модели, но только в том случае если вы сами не определили какое поле будет первичным ключом.

2.4. Написание тестов

Вы можете запустить тесты для вашего приложения используя команду manage.py test :

Если вы запустите это, то увидите что выполнилось около 420 тестов. Это удивляет, так как мы написали только один. Произошло это потому, что по умолчанию Django запускает тесты для всех установленных приложений. Когда вы добавляли приложение contacts в наш проект, то могли увидеть, что там по умолчанию были добавлены несколько встроенных приложений Django. Дополнительные 419 тестов были взяты оттуда.

Если же вы захотите запустить тесты для определенного приложения — укажите имя приложения в команде:

Еще одна интересная вещь на заметку, прежде чем двигаться дальше — первая и последняя строка вывода: Creating test database и Destroying test database . Некоторым тестам необходим доступ к базе данных, и поскольку мы не хотим мешать тестовые данные с «реальными» (по разным причинам, не последней из которых является предопределенность), Django услужливо создает тестовую базу для нас, прежде чем запускать тесты. По существу, создается новая база данных, и потом запускается syncdb для нее. Если тестовый класс является потомком класса TestCase (как у нас), Django так же сбросит данные в значения по умолчанию после запуска каждого теста, так что изменения в одном из тестов не затронут другие.

2.5. Резюме

• Модель определяет поля в таблице, и содержит бизнес-логику.
• Команда syncdb создает таблицы в вашей базе данных из моделей. В Django версии 1.7 и выше вместо команды syncdb необходимо использовать сначала команду makemigrations — для создания миграций, а после этого команду migrate — для внесение изменений в базу.
• Менеджер модели позволяет вам оперировать коллекциями экземпляров: запросы, создание и т. д..
• Пишите модульные тесты для методов, которые вы добавили в модель.
• Команда управления test запускает модульные тесты на выполнение.

Примечание переводчика:
Для того чтобы протестировать наше, пока еще пустое, приложение нужно выполнить следующую команду:

Это запустит встроенный сервер, функционал которого любезно предоставляет нам Django. В параметрах после runserver указывается ip-адрес и порт, который будет слушаться работающим сервер. В нашем случае сервер будет принимать запросы от всех ip-адресов при обращении на 8080 порт.

django-admin and manage.py ¶

django-admin is Django’s command-line utility for administrative tasks. This document outlines all it can do.

In addition, manage.py is automatically created in each Django project. It does the same thing as django-admin but also sets the DJANGO_SETTINGS_MODULE environment variable so that it points to your project’s settings.py file.

The django-admin script should be on your system path if you installed Django via pip . If it’s not in your path, ensure you have your virtual environment activated.

Generally, when working on a single Django project, it’s easier to use manage.py than django-admin . If you need to switch between multiple Django settings files, use django-admin with DJANGO_SETTINGS_MODULE or the —settings command line option.

The command-line examples throughout this document use django-admin to be consistent, but any example can use manage.py or python -m django just as well.

Usage¶

command should be one of the commands listed in this document. options , which is optional, should be zero or more of the options available for the given command.

Getting runtime help¶

Run django-admin help to display usage information and a list of the commands provided by each application.

Run django-admin help —commands to display a list of all available commands.

Run django-admin help <command> to display a description of the given command and a list of its available options.

App names¶

Many commands take a list of “app names.” An “app name” is the basename of the package containing your models. For example, if your INSTALLED_APPS contains the string ‘mysite.blog’ , the app name is blog .

Determining the version¶

Run django-admin version to display the current Django version.

The output follows the schema described in PEP 440:

Displaying debug output¶

Use —verbosity , where it is supported, to specify the amount of notification and debug information that django-admin prints to the console.

Available commands¶

check ¶

Uses the system check framework to inspect the entire Django project for common problems.

By default, all apps will be checked. You can check a subset of apps by providing a list of app labels as arguments:

The system check framework performs many different types of checks that are categorized with tags . You can use these tags to restrict the checks performed to just those in a particular category. For example, to perform only models and compatibility checks, run:

Specifies the database to run checks requiring database access:

By default, these checks will not be run.

Lists all available tags.

Activates some additional checks that are only relevant in a deployment setting.

You can use this option in your local development environment, but since your local development settings module may not have many of your production settings, you will probably want to point the check command at a different settings module, either by setting the DJANGO_SETTINGS_MODULE environment variable, or by passing the —settings option:

Or you could run it directly on a production or staging deployment to verify that the correct settings are in use (omitting —settings ). You could even make it part of your integration test suite.

Specifies the message level that will cause the command to exit with a non-zero status. Default is ERROR .

compilemessages ¶

Compiles .po files created by makemessages to .mo files for use with the built-in gettext support. See Internationalization and localization .

—locale LOCALE , -l LOCALE ¶

Specifies the locale(s) to process. If not provided, all locales are processed.

—exclude EXCLUDE , -x EXCLUDE ¶

Specifies the locale(s) to exclude from processing. If not provided, no locales are excluded.

Includes fuzzy translations into compiled files.

Ignores directories matching the given glob -style pattern. Use multiple times to ignore more.

createcachetable ¶

Creates the cache tables for use with the database cache backend using the information from your settings file. See Django’s cache framework for more information.

Specifies the database in which the cache table(s) will be created. Defaults to default .

Prints the SQL that would be run without actually running it, so you can customize it or use the migrations framework.

dbshell ¶

Runs the command-line client for the database engine specified in your ENGINE setting, with the connection parameters specified in your USER , PASSWORD , etc., settings.

• For PostgreSQL, this runs the psql command-line client.
• For MySQL, this runs the mysql command-line client.
• For SQLite, this runs the sqlite3 command-line client.
• For Oracle, this runs the sqlplus command-line client.

This command assumes the programs are on your PATH so that a call to the program name ( psql , mysql , sqlite3 , sqlplus ) will find the program in the right place. There’s no way to specify the location of the program manually.

Specifies the database onto which to open a shell. Defaults to default .

Any arguments following a — divider will be passed on to the underlying command-line client. For example, with PostgreSQL you can use the psql command’s -c flag to execute a raw SQL query directly:

On MySQL/MariaDB, you can do this with the mysql command’s -e flag:

Be aware that not all options set in the OPTIONS part of your database configuration in DATABASES are passed to the command-line client, e.g. ‘isolation_level’ .

diffsettings ¶

Displays differences between the current settings file and Django’s default settings (or another settings file specified by —default ).

Settings that don’t appear in the defaults are followed by "###" . For example, the default settings don’t define ROOT_URLCONF , so ROOT_URLCONF is followed by "###" in the output of diffsettings .

Displays all settings, even if they have Django’s default value. Such settings are prefixed by "###" .

The settings module to compare the current settings against. Leave empty to compare against Django’s default settings.

Specifies the output format. Available values are hash and unified . hash is the default mode that displays the output that’s described above. unified displays the output similar to diff -u . Default settings are prefixed with a minus sign, followed by the changed setting prefixed with a plus sign.

dumpdata ¶

Outputs to standard output all data in the database associated with the named application(s).

If no application name is provided, all installed applications will be dumped.

The output of dumpdata can be used as input for loaddata .

Note that dumpdata uses the default manager on the model for selecting the records to dump. If you’re using a custom manager as the default manager and it filters some of the available records, not all of the objects will be dumped.

Uses Django’s base manager, dumping records which might otherwise be filtered or modified by a custom manager.

Specifies the serialization format of the output. Defaults to JSON. Supported formats are listed in Serialization formats .

Specifies the number of indentation spaces to use in the output. Defaults to None which displays all data on single line.

—exclude EXCLUDE , -e EXCLUDE ¶

Prevents specific applications or models (specified in the form of app_label.ModelName ) from being dumped. If you specify a model name, then only that model will be excluded, rather than the entire application. You can also mix application names and model names.

If you want to exclude multiple applications, pass —exclude more than once:

Specifies the database from which data will be dumped. Defaults to default .

Uses the natural_key() model method to serialize any foreign key and many-to-many relationship to objects of the type that defines the method. If you’re dumping contrib.auth Permission objects or contrib.contenttypes ContentType objects, you should probably use this flag. See the natural keys documentation for more details on this and the next option.

Omits the primary key in the serialized data of this object since it can be calculated during deserialization.

Outputs only the objects specified by a comma separated list of primary keys. This is only available when dumping one model. By default, all the records of the model are output.

—output OUTPUT , -o OUTPUT ¶

Specifies a file to write the serialized data to. By default, the data goes to standard output.

When this option is set and —verbosity is greater than 0 (the default), a progress bar is shown in the terminal.

Fixtures compression¶

The output file can be compressed with one of the bz2 , gz , lzma , or xz formats by ending the filename with the corresponding extension. For example, to output the data as a compressed JSON file:

flush ¶

Removes all data from the database and re-executes any post-synchronization handlers. The table of which migrations have been applied is not cleared.

If you would rather start from an empty database and rerun all migrations, you should drop and recreate the database and then run migrate instead.

Suppresses all user prompts.

Specifies the database to flush. Defaults to default .

inspectdb ¶

Introspects the database tables in the database pointed-to by the NAME setting and outputs a Django model module (a models.py file) to standard output.

You may choose what tables or views to inspect by passing their names as arguments. If no arguments are provided, models are created for views only if the —include-views option is used. Models for partition tables are created on PostgreSQL if the —include-partitions option is used.

Use this if you have a legacy database with which you’d like to use Django. The script will inspect the database and create a model for each table within it.

As you might expect, the created models will have an attribute for every field in the table. Note that inspectdb has a few special cases in its field-name output:

• If inspectdb cannot map a column’s type to a model field type, it’ll use TextField and will insert the Python comment ‘This field type is a guess.’ next to the field in the generated model. The recognized fields may depend on apps listed in INSTALLED_APPS . For example, django.contrib.postgres adds recognition for several PostgreSQL-specific field types.
• If the database column name is a Python reserved word (such as ‘pass’ , ‘class’ or ‘for’ ), inspectdb will append ‘_field’ to the attribute name. For example, if a table has a column ‘for’ , the generated model will have a field ‘for_field’ , with the db_column attribute set to ‘for’ . inspectdb will insert the Python comment ‘Field renamed because it was a Python reserved word.’ next to the field.

This feature is meant as a shortcut, not as definitive model generation. After you run it, you’ll want to look over the generated models yourself to make customizations. In particular, you’ll need to rearrange models’ order, so that models that refer to other models are ordered properly.

Django doesn’t create database defaults when a default is specified on a model field. Similarly, database defaults aren’t translated to model field defaults or detected in any fashion by inspectdb .

By default, inspectdb creates unmanaged models. That is, managed = False in the model’s Meta class tells Django not to manage each table’s creation, modification, and deletion. If you do want to allow Django to manage the table’s lifecycle, you’ll need to change the managed option to True (or remove it because True is its default value).

Database-specific notes¶

Oracle¶

• Models are created for materialized views if —include-views is used.

PostgreSQL¶

• Models are created for foreign tables.
• Models are created for materialized views if —include-views is used.
• Models are created for partition tables if —include-partitions is used.

Specifies the database to introspect. Defaults to default .

If this option is provided, models are also created for partitions.

Only support for PostgreSQL is implemented.

If this option is provided, models are also created for database views.

loaddata ¶

Searches for and loads the contents of the named fixture into the database.

Specifies the database into which the data will be loaded. Defaults to default .

Ignores fields and models that may have been removed since the fixture was originally generated.

Specifies a single app to look for fixtures in rather than looking in all apps.

Specifies the serialization format (e.g., json or xml ) for fixtures read from stdin .

—exclude EXCLUDE , -e EXCLUDE ¶

Excludes loading the fixtures from the given applications and/or models (in the form of app_label or app_label.ModelName ). Use the option multiple times to exclude more than one app or model.

What’s a “fixture”?¶

A fixture is a collection of files that contain the serialized contents of the database. Each fixture has a unique name, and the files that comprise the fixture can be distributed over multiple directories, in multiple applications.

Django will search in three locations for fixtures:

1. In the fixtures directory of every installed application
2. In any directory named in the FIXTURE_DIRS setting
3. In the literal path named by the fixture

Django will load any and all fixtures it finds in these locations that match the provided fixture names.

If the named fixture has a file extension, only fixtures of that type will be loaded. For example:

would only load JSON fixtures called mydata . The fixture extension must correspond to the registered name of a serializer (e.g., json or xml ).

If you omit the extensions, Django will search all available fixture types for a matching fixture. For example:

would look for any fixture of any fixture type called mydata . If a fixture directory contained mydata.json , that fixture would be loaded as a JSON fixture.

The fixtures that are named can include directory components. These directories will be included in the search path. For example:

would search <app_label>/fixtures/foo/bar/mydata.json for each installed application, <dirname>/foo/bar/mydata.json for each directory in FIXTURE_DIRS , and the literal path foo/bar/mydata.json .

When fixture files are processed, the data is saved to the database as is. Model defined save() methods are not called, and any pre_save or post_save signals will be called with raw=True since the instance only contains attributes that are local to the model. You may, for example, want to disable handlers that access related fields that aren’t present during fixture loading and would otherwise raise an exception:

You could also write a decorator to encapsulate this logic:

Just be aware that this logic will disable the signals whenever fixtures are deserialized, not just during loaddata .

Note that the order in which fixture files are processed is undefined. However, all fixture data is installed as a single transaction, so data in one fixture can reference data in another fixture. If the database backend supports row-level constraints, these constraints will be checked at the end of the transaction.

The dumpdata command can be used to generate input for loaddata .

Compressed fixtures¶

Fixtures may be compressed in zip , gz , bz2 , lzma , or xz format. For example:

would look for any of mydata.json , mydata.json.zip , mydata.json.gz , mydata.json.bz2 , mydata.json.lzma , or mydata.json.xz . The first file contained within a compressed archive is used.

Note that if two fixtures with the same name but different fixture type are discovered (for example, if mydata.json and mydata.xml.gz were found in the same fixture directory), fixture installation will be aborted, and any data installed in the call to loaddata will be removed from the database.

MySQL with MyISAM and fixtures

The MyISAM storage engine of MySQL doesn’t support transactions or constraints, so if you use MyISAM, you won’t get validation of fixture data, or a rollback if multiple transaction files are found.

Database-specific fixtures¶

If you’re in a multi-database setup, you might have fixture data that you want to load onto one database, but not onto another. In this situation, you can add a database identifier into the names of your fixtures.

For example, if your DATABASES setting has a ‘users’ database defined, name the fixture mydata.users.json or mydata.users.json.gz and the fixture will only be loaded when you specify you want to load data into the users database.

Loading fixtures from stdin ¶

You can use a dash as the fixture name to load input from sys.stdin . For example:

When reading from stdin , the —format option is required to specify the serialization format of the input (e.g., json or xml ).

Loading from stdin is useful with standard input and output redirections. For example:

makemessages ¶

Runs over the entire source tree of the current directory and pulls out all strings marked for translation. It creates (or updates) a message file in the conf/locale (in the Django tree) or locale (for project and application) directory. After making changes to the messages files you need to compile them with compilemessages for use with the builtin gettext support. See the i18n documentation for details.

This command doesn’t require configured settings. However, when settings aren’t configured, the command can’t ignore the MEDIA_ROOT and STATIC_ROOT directories or include LOCALE_PATHS .

Updates the message files for all available languages.

—extension EXTENSIONS , -e EXTENSIONS ¶

Specifies a list of file extensions to examine (default: html , txt , py or js if —domain is js ).

Separate multiple extensions with commas or use -e or —extension multiple times:

Specifies the locale(s) to process.

—exclude EXCLUDE , -x EXCLUDE ¶

Specifies the locale(s) to exclude from processing. If not provided, no locales are excluded.

Specifies the domain of the messages files. Supported options are:

• django for all *.py , *.html and *.txt files (default)
• djangojs for *.js files

Follows symlinks to directories when looking for new translation strings.

Ignores files or directories matching the given glob -style pattern. Use multiple times to ignore more.

These patterns are used by default: ‘CVS’ , ‘.*’ , ‘*

Disables the default values of —ignore .

Disables breaking long message lines into several lines in language files.

Suppresses writing ‘ #: filename:line ’ comment lines in language files. Using this option makes it harder for technically skilled translators to understand each message’s context.

Controls #: filename:line comment lines in language files. If the option is:

• full (the default if not given): the lines include both file name and line number.
• file : the line number is omitted.
• never : the lines are suppressed (same as —no-location ).

Requires gettext 0.19 or newer.

Prevents deleting the temporary .pot files generated before creating the .po file. This is useful for debugging errors which may prevent the final language files from being created.

See Customizing the makemessages command for instructions on how to customize the keywords that makemessages passes to xgettext .

makemigrations ¶

Creates new migrations based on the changes detected to your models. Migrations, their relationship with apps and more are covered in depth in the migrations documentation .

Providing one or more app names as arguments will limit the migrations created to the app(s) specified and any dependencies needed (the table at the other end of a ForeignKey , for example).

To add migrations to an app that doesn’t have a migrations directory, run makemigrations with the app’s app_label .

Suppresses all user prompts. If a suppressed prompt cannot be resolved automatically, the command will exit with error code 3.

Outputs an empty migration for the specified apps, for manual editing. This is for advanced users and should not be used unless you are familiar with the migration format, migration operations, and the dependencies between your migrations.

Shows what migrations would be made without actually writing any migrations files to disk. Using this option along with —verbosity 3 will also show the complete migrations files that would be written.

Enables fixing of migration conflicts.

—name NAME , -n NAME ¶

Allows naming the generated migration(s) instead of using a generated name. The name must be a valid Python identifier .

Generate migration files without Django version and timestamp header.

Makes makemigrations exit with a non-zero status when model changes without migrations are detected.

Diverts log output and input prompts to stderr , writing only paths of generated migration files to stdout .

migrate ¶

Synchronizes the database state with the current set of models and migrations. Migrations, their relationship with apps and more are covered in depth in the migrations documentation .

The behavior of this command changes depending on the arguments provided:

• No arguments: All apps have all of their migrations run.
• <app_label> : The specified app has its migrations run, up to the most recent migration. This may involve running other apps’ migrations too, due to dependencies.
• <app_label> <migrationname> : Brings the database schema to a state where the named migration is applied, but no later migrations in the same app are applied. This may involve unapplying migrations if you have previously migrated past the named migration. You can use a prefix of the migration name, e.g. 0001 , as long as it’s unique for the given app name. Use the name zero to migrate all the way back i.e. to revert all applied migrations for an app.

When unapplying migrations, all dependent migrations will also be unapplied, regardless of <app_label> . You can use —plan to check which migrations will be unapplied.

Specifies the database to migrate. Defaults to default .

Marks the migrations up to the target one (following the rules above) as applied, but without actually running the SQL to change your database schema.

This is intended for advanced users to manipulate the current migration state directly if they’re manually applying changes; be warned that using —fake runs the risk of putting the migration state table into a state where manual recovery will be needed to make migrations run correctly.

Allows Django to skip an app’s initial migration if all database tables with the names of all models created by all CreateModel operations in that migration already exist. This option is intended for use when first running migrations against a database that preexisted the use of migrations. This option does not, however, check for matching database schema beyond matching table names and so is only safe to use if you are confident that your existing schema matches what is recorded in your initial migration.

Shows the migration operations that will be performed for the given migrate command.

Allows creating tables for apps without migrations. While this isn’t recommended, the migrations framework is sometimes too slow on large projects with hundreds of models.

Suppresses all user prompts. An example prompt is asking about removing stale content types.

Makes migrate exit with a non-zero status when unapplied migrations are detected.

Deletes nonexistent migrations from the django_migrations table. This is useful when migration files replaced by a squashed migration have been removed. See Squashing migrations for more details.

optimizemigration ¶

Optimizes the operations for the named migration and overrides the existing file. If the migration contains functions that must be manually copied, the command creates a new migration file suffixed with _optimized that is meant to replace the named migration.

Makes optimizemigration exit with a non-zero status when a migration can be optimized.

runserver ¶

Starts a lightweight development web server on the local machine. By default, the server runs on port 8000 on the IP address 127.0.0.1 . You can pass in an IP address and port number explicitly.

If you run this script as a user with normal privileges (recommended), you might not have access to start a port on a low port number. Low port numbers are reserved for the superuser (root).

This server uses the WSGI application object specified by the WSGI_APPLICATION setting.

DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests. (And that’s how it’s gonna stay. We’re in the business of making web frameworks, not web servers, so improving this server to be able to handle a production environment is outside the scope of Django.)

The development server automatically reloads Python code for each request, as needed. You don’t need to restart the server for code changes to take effect. However, some actions like adding files don’t trigger a restart, so you’ll have to restart the server in these cases.

If you’re using Linux or MacOS and install both pywatchman and the Watchman service, kernel signals will be used to autoreload the server (rather than polling file modification timestamps each second). This offers better performance on large projects, reduced response time after code changes, more robust change detection, and a reduction in power usage. Django supports pywatchman 1.2.0 and higher.

Large directories with many files may cause performance issues

When using Watchman with a project that includes large non-Python directories like node_modules , it’s advisable to ignore this directory for optimal performance. See the watchman documentation for information on how to do this.

The default timeout of Watchman client is 5 seconds. You can change it by setting the DJANGO_WATCHMAN_TIMEOUT environment variable.

When you start the server, and each time you change Python code while the server is running, the system check framework will check your entire Django project for some common errors (see the check command). If any errors are found, they will be printed to standard output. You can use the —skip-checks option to skip running system checks.

You can run as many concurrent servers as you want, as long as they’re on separate ports by executing django-admin runserver more than once.

Note that the default IP address, 127.0.0.1 , is not accessible from other machines on your network. To make your development server viewable to other machines on the network, use its own IP address (e.g. 192.168.2.1 ) or 0.0.0.0 or :: (with IPv6 enabled).

You can provide an IPv6 address surrounded by brackets (e.g. [200a::1]:8000 ). This will automatically enable IPv6 support.

A hostname containing ASCII-only characters can also be used.

If the staticfiles contrib app is enabled (default in new projects) the runserver command will be overridden with its own runserver command.

Logging of each request and response of the server is sent to the django.server logger.

Disables the auto-reloader. This means any Python code changes you make while the server is running will not take effect if the particular Python modules have already been loaded into memory.

Disables use of threading in the development server. The server is multithreaded by default.

Uses IPv6 for the development server. This changes the default IP address from 127.0.0.1 to ::1 .

Support for the —skip-checks option was added.

Examples of using different ports and addresses¶

Port 8000 on IP address 127.0.0.1 :

Port 8000 on IP address 1.2.3.4 :

Port 7000 on IP address 127.0.0.1 :

Port 7000 on IP address 1.2.3.4 :

Port 8000 on IPv6 address ::1 :

Port 7000 on IPv6 address ::1 :

Port 7000 on IPv6 address 2001:0db8:1234:5678::9 :

Port 8000 on IPv4 address of host localhost :

Port 8000 on IPv6 address of host localhost :

Serving static files with the development server¶

By default, the development server doesn’t serve any static files for your site (such as CSS files, images, things under MEDIA_URL and so forth). If you want to configure Django to serve static media, read How to manage static files (e.g. images, JavaScript, CSS) .

sendtestemail ¶

Sends a test email (to confirm email sending through Django is working) to the recipient(s) specified. For example:

There are a couple of options, and you may use any combination of them together:

Mails the email addresses specified in MANAGERS using mail_managers() .

Mails the email addresses specified in ADMINS using mail_admins() .

shell ¶

Starts the Python interactive interpreter.

Specifies the shell to use. By default, Django will use IPython or bpython if either is installed. If both are installed, specify which one you want like so:

If you have a “rich” shell installed but want to force use of the “plain” Python interpreter, use python as the interface name, like so:

Disables reading the startup script for the “plain” Python interpreter. By default, the script pointed to by the PYTHONSTARTUP environment variable or the

/.pythonrc.py script is read.

—command COMMAND , -c COMMAND ¶

Lets you pass a command as a string to execute it as Django, like so:

You can also pass code in on standard input to execute it. For example:

On Windows, the REPL is output due to implementation limits of select.select() on that platform.

showmigrations ¶

Shows all migrations in a project. You can choose from one of two formats:

Lists all of the apps Django knows about, the migrations available for each app, and whether or not each migration is applied (marked by an [X] next to the migration name). For a —verbosity of 2 and above, the applied datetimes are also shown.

Apps without migrations are also listed, but have (no migrations) printed under them.

This is the default output format.

Shows the migration plan Django will follow to apply migrations. Like —list , applied migrations are marked by an [X] . For a —verbosity of 2 and above, all dependencies of a migration will also be shown.

app_label s arguments limit the output, however, dependencies of provided apps may also be included.

Specifies the database to examine. Defaults to default .

sqlflush ¶

Prints the SQL statements that would be executed for the flush command.

Specifies the database for which to print the SQL. Defaults to default .

sqlmigrate ¶

Prints the SQL for the named migration. This requires an active database connection, which it will use to resolve constraint names; this means you must generate the SQL against a copy of the database you wish to later apply it on.

Note that sqlmigrate doesn’t colorize its output.

Generates the SQL for unapplying the migration. By default, the SQL created is for running the migration in the forwards direction.

Specifies the database for which to generate the SQL. Defaults to default .

sqlsequencereset ¶

Prints the SQL statements for resetting sequences for the given app name(s).

Sequences are indexes used by some database engines to track the next available number for automatically incremented fields.

Use this command to generate SQL which will fix cases where a sequence is out of sync with its automatically incremented field data.

Specifies the database for which to print the SQL. Defaults to default .

squashmigrations ¶

Squashes the migrations for app_label up to and including migration_name down into fewer migrations, if possible. The resulting squashed migrations can live alongside the unsquashed ones safely. For more information, please read Squashing migrations .

When start_migration_name is given, Django will only include migrations starting from and including this migration. This helps to mitigate the squashing limitation of RunPython and django.db.migrations.operations.RunSQL migration operations.

Disables the optimizer when generating a squashed migration. By default, Django will try to optimize the operations in your migrations to reduce the size of the resulting file. Use this option if this process is failing or creating incorrect migrations, though please also file a Django bug report about the behavior, as optimization is meant to be safe.

Suppresses all user prompts.

Sets the name of the squashed migration. When omitted, the name is based on the first and last migration, with _squashed_ in between.

Generate squashed migration file without Django version and timestamp header.

startapp ¶

Creates a Django app directory structure for the given app name in the current directory or the given destination.

By default, the new directory contains a models.py file and other app template files. If only the app name is given, the app directory will be created in the current working directory.

If the optional destination is provided, Django will use that existing directory rather than creating a new one. You can use ‘.’ to denote the current working directory.

Provides the path to a directory with a custom app template file, or a path to an uncompressed archive ( .tar ) or a compressed archive ( .tar.gz , .tar.bz2 , .tar.xz , .tar.lzma , .tgz , .tbz2 , .txz , .tlz , .zip ) containing the app template files.

For example, this would look for an app template in the given directory when creating the myapp app:

Django will also accept URLs ( http , https , ftp ) to compressed archives with the app template files, downloading and extracting them on the fly.

For example, taking advantage of GitHub’s feature to expose repositories as zip files, you can use a URL like:

Specifies which file extensions in the app template should be rendered with the template engine. Defaults to py .

—name FILES , -n FILES ¶

Specifies which files in the app template (in addition to those matching —extension ) should be rendered with the template engine. Defaults to an empty list.

—exclude DIRECTORIES , -x DIRECTORIES ¶

Specifies which directories in the app template should be excluded, in addition to .git and __pycache__ . If this option is not provided, directories named __pycache__ or starting with . will be excluded.

The template context used for all matching files is:

• Any option passed to the startapp command (among the command’s supported options)
• app_name – the app name as passed to the command
• app_directory – the full path of the newly created app
• camel_case_app_name – the app name in camel case format
• docs_version – the version of the documentation: ‘dev’ or ‘1.x’
• django_version – the version of Django, e.g. ‘2.0.3’

When the app template files are rendered with the Django template engine (by default all *.py files), Django will also replace all stray template variables contained. For example, if one of the Python files contains a docstring explaining a particular feature related to template rendering, it might result in an incorrect example.

To work around this problem, you can use the templatetag template tag to “escape” the various parts of the template syntax.

In addition, to allow Python template files that contain Django template language syntax while also preventing packaging systems from trying to byte-compile invalid *.py files, template files ending with .py-tpl will be renamed to .py .

startproject ¶

Creates a Django project directory structure for the given project name in the current directory or the given destination.

By default, the new directory contains manage.py and a project package (containing a settings.py and other files).

If only the project name is given, both the project directory and project package will be named <projectname> and the project directory will be created in the current working directory.

If the optional destination is provided, Django will use that existing directory as the project directory, and create manage.py and the project package within it. Use ‘.’ to denote the current working directory.

Specifies a directory, file path, or URL of a custom project template. See the startapp —template documentation for examples and usage.

—extension EXTENSIONS , -e EXTENSIONS ¶

Specifies which file extensions in the project template should be rendered with the template engine. Defaults to py .

—name FILES , -n FILES ¶

Specifies which files in the project template (in addition to those matching —extension ) should be rendered with the template engine. Defaults to an empty list.

—exclude DIRECTORIES , -x DIRECTORIES ¶

Specifies which directories in the project template should be excluded, in addition to .git and __pycache__ . If this option is not provided, directories named __pycache__ or starting with . will be excluded.

• Any option passed to the startproject command (among the command’s supported options)
• project_name – the project name as passed to the command
• project_directory – the full path of the newly created project
• secret_key – a random key for the SECRET_KEY setting
• docs_version – the version of the documentation: ‘dev’ or ‘1.x’
• django_version – the version of Django, e.g. ‘2.0.3’

Please also see the rendering warning as mentioned for startapp .

Runs tests for all installed apps. See Testing in Django for more information.

Stops running tests and reports the failure immediately after a test fails.

Controls the test runner class that is used to execute tests. This value overrides the value provided by the TEST_RUNNER setting.

Suppresses all user prompts. A typical prompt is a warning about deleting an existing test database.

Test runner options¶

The test command receives options on behalf of the specified —testrunner . These are the options of the default test runner: DiscoverRunner .

Preserves the test database between test runs. This has the advantage of skipping both the create and destroy actions which can greatly decrease the time to run tests, especially those in a large test suite. If the test database does not exist, it will be created on the first run and then preserved for each subsequent run. Unless the MIGRATE test setting is False , any unapplied migrations will also be applied to the test database before running the test suite.

Randomizes the order of tests before running them. This can help detect tests that aren’t properly isolated. The test order generated by this option is a deterministic function of the integer seed given. When no seed is passed, a seed is chosen randomly and printed to the console. To repeat a particular test order, pass a seed. The test orders generated by this option preserve Django’s guarantees on test order . They also keep tests grouped by test case class.

The shuffled orderings also have a special consistency property useful when narrowing down isolation issues. Namely, for a given seed and when running a subset of tests, the new order will be the original shuffling restricted to the smaller set. Similarly, when adding tests while keeping the seed the same, the order of the original tests will be the same in the new order.

Sorts test cases in the opposite execution order. This may help in debugging the side effects of tests that aren’t properly isolated. Grouping by test class is preserved when using this option. This can be used in conjunction with —shuffle to reverse the order for a particular seed.

Sets the DEBUG setting to True prior to running tests. This may help troubleshoot test failures.

Enables SQL logging for failing tests. If —verbosity is 2 , then queries in passing tests are also output.

—parallel [N] ¶ DJANGO_TEST_PROCESSES ¶

Runs tests in separate parallel processes. Since modern processors have multiple cores, this allows running tests significantly faster.

Using —parallel without a value, or with the value auto , runs one test process per core according to multiprocessing.cpu_count() . You can override this by passing the desired number of processes, e.g. —parallel 4 , or by setting the DJANGO_TEST_PROCESSES environment variable.

Django distributes test cases — unittest.TestCase subclasses — to subprocesses. If there are fewer test cases than configured processes, Django will reduce the number of processes accordingly.

Each process gets its own database. You must ensure that different test cases don’t access the same resources. For instance, test cases that touch the filesystem should create a temporary directory for their own use.

If you have test classes that cannot be run in parallel, you can use SerializeMixin to run them sequentially. See Enforce running test classes sequentially .

This option requires the third-party tblib package to display tracebacks correctly:

This feature isn’t available on Windows. It doesn’t work with the Oracle database backend either.

If you want to use pdb while debugging tests, you must disable parallel execution ( —parallel=1 ). You’ll see something like bdb.BdbQuit if you don’t.

When test parallelization is enabled and a test fails, Django may be unable to display the exception traceback. This can make debugging difficult. If you encounter this problem, run the affected test without parallelization to see the traceback of the failure.

This is a known limitation. It arises from the need to serialize objects in order to exchange them between processes. See What can be pickled and unpickled? for details.

Support for the value auto was added.

Runs only tests marked with the specified tags . May be specified multiple times and combined with test —exclude-tag .

Tests that fail to load are always considered matching.

In older versions, tests that failed to load did not match tags.

Excludes tests marked with the specified tags . May be specified multiple times and combined with test —tag .

Runs test methods and classes matching test name patterns, in the same way as unittest’s -k option . Can be specified multiple times.

Spawns a pdb debugger at each test error or failure. If you have it installed, ipdb is used instead.

Discards output ( stdout and stderr ) for passing tests, in the same way as unittest’s —buffer option .

Django automatically calls faulthandler.enable() when starting the tests, which allows it to print a traceback if the interpreter crashes. Pass —no-faulthandler to disable this behavior.

Outputs timings, including database setup and total run time.

testserver ¶

Runs a Django development server (as in runserver ) using data from the given fixture(s).

For example, this command:

…would perform the following steps:

1. Create a test database, as described in The test database .
2. Populate the test database with fixture data from the given fixtures. (For more on fixtures, see the documentation for loaddata above.)
3. Runs the Django development server (as in runserver ), pointed at this newly created test database instead of your production database.

This is useful in a number of ways:

• When you’re writing unit tests of how your views act with certain fixture data, you can use testserver to interact with the views in a web browser, manually.
• Let’s say you’re developing your Django application and have a “pristine” copy of a database that you’d like to interact with. You can dump your database to a fixture (using the dumpdata command, explained above), then use testserver to run your web application with that data. With this arrangement, you have the flexibility of messing up your data in any way, knowing that whatever data changes you’re making are only being made to a test database.

Note that this server does not automatically detect changes to your Python source code (as runserver does). It does, however, detect changes to templates.

Specifies a different port, or IP address and port, from the default of 127.0.0.1:8000 . This value follows exactly the same format and serves exactly the same function as the argument to the runserver command.

To run the test server on port 7000 with fixture1 and fixture2 :

(The above statements are equivalent. We include both of them to demonstrate that it doesn’t matter whether the options come before or after the fixture arguments.)

To run on 1.2.3.4:7000 with a test fixture:

Suppresses all user prompts. A typical prompt is a warning about deleting an existing test database.

Commands provided by applications¶

Some commands are only available when the django.contrib application that implements them has been enabled . This section describes them grouped by their application.

django.contrib.auth ¶

changepassword ¶

This command is only available if Django’s authentication system ( django.contrib.auth ) is installed.

Allows changing a user’s password. It prompts you to enter a new password twice for the given user. If the entries are identical, this immediately becomes the new password. If you do not supply a user, the command will attempt to change the password whose username matches the current user.

Specifies the database to query for the user. Defaults to default .

createsuperuser ¶

This command is only available if Django’s authentication system ( django.contrib.auth ) is installed.

Creates a superuser account (a user who has all permissions). This is useful if you need to create an initial superuser account or if you need to programmatically generate superuser accounts for your site(s).

When run interactively, this command will prompt for a password for the new superuser account. When run non-interactively, you can provide a password by setting the DJANGO_SUPERUSER_PASSWORD environment variable. Otherwise, no password will be set, and the superuser account will not be able to log in until a password has been manually set for it.

In non-interactive mode, the USERNAME_FIELD and required fields (listed in REQUIRED_FIELDS ) fall back to DJANGO_SUPERUSER_<uppercase_field_name> environment variables, unless they are overridden by a command line argument. For example, to provide an email field, you can use DJANGO_SUPERUSER_EMAIL environment variable.

Suppresses all user prompts. If a suppressed prompt cannot be resolved automatically, the command will exit with error code 1.

—username USERNAME ¶ —email EMAIL ¶

The username and email address for the new account can be supplied by using the —username and —email arguments on the command line. If either of those is not supplied, createsuperuser will prompt for it when running interactively.

Specifies the database into which the superuser object will be saved.

You can subclass the management command and override get_input_data() if you want to customize data input and validation. Consult the source code for details on the existing implementation and the method’s parameters. For example, it could be useful if you have a ForeignKey in REQUIRED_FIELDS and want to allow creating an instance instead of entering the primary key of an existing instance.

django.contrib.contenttypes ¶

remove_stale_contenttypes ¶

This command is only available if Django’s contenttypes app ( django.contrib.contenttypes ) is installed.

Deletes stale content types (from deleted models) in your database. Any objects that depend on the deleted content types will also be deleted. A list of deleted objects will be displayed before you confirm it’s okay to proceed with the deletion.

Specifies the database to use. Defaults to default .

Deletes stale content types including ones from previously installed apps that have been removed from INSTALLED_APPS . Defaults to False .

django.contrib.gis ¶

ogrinspect ¶

This command is only available if GeoDjango ( django.contrib.gis ) is installed.

Please refer to its description in the GeoDjango documentation.

django.contrib.sessions ¶

clearsessions ¶

Can be run as a cron job or directly to clean out expired sessions.

django.contrib.sitemaps ¶

ping_google ¶

This command is only available if the Sitemaps framework ( django.contrib.sitemaps ) is installed.

Please refer to its description in the Sitemaps documentation.

django.contrib.staticfiles ¶

collectstatic ¶

This command is only available if the static files application ( django.contrib.staticfiles ) is installed.

Please refer to its description in the staticfiles documentation.

findstatic ¶

This command is only available if the static files application ( django.contrib.staticfiles ) is installed.

Please refer to its description in the staticfiles documentation.

Default options¶

Although some commands may allow their own custom options, every command allows for the following options by default:

Adds the given filesystem path to the Python import search path. If this isn’t provided, django-admin will use the PYTHONPATH environment variable.

This option is unnecessary in manage.py , because it takes care of setting the Python path for you.

Specifies the settings module to use. The settings module should be in Python package syntax, e.g. mysite.settings . If this isn’t provided, django-admin will use the DJANGO_SETTINGS_MODULE environment variable.

This option is unnecessary in manage.py , because it uses settings.py from the current project by default.

Displays a full stack trace when a CommandError is raised. By default, django-admin will show an error message when a CommandError occurs and a full stack trace for any other exception.

This option is ignored by runserver .

Specifies the amount of notification and debug information that a command should print to the console.

• 0 means no output.
• 1 means normal output (default).
• 2 means verbose output.
• 3 means very verbose output.

This option is ignored by runserver .

Disables colorized command output. Some commands format their output to be colorized. For example, errors will be printed to the console in red and SQL statements will be syntax highlighted.

Forces colorization of the command output if it would otherwise be disabled as discussed in Syntax coloring . For example, you may want to pipe colored output to another command.

Skips running system checks prior to running the command. This option is only available if the requires_system_checks command attribute is not an empty list or tuple.

Extra niceties¶

Syntax coloring¶

The django-admin / manage.py commands will use pretty color-coded output if your terminal supports ANSI-colored output. It won’t use the color codes if you’re piping the command’s output to another program unless the —force-color option is used.

Windows support¶

On Windows 10, the Windows Terminal application, VS Code, and PowerShell (where virtual terminal processing is enabled) allow colored output, and are supported by default.

Under Windows, the legacy cmd.exe native console doesn’t support ANSI escape sequences so by default there is no color output. In this case either of two third-party libraries are needed:

Install colorama, a Python package that translates ANSI color codes into Windows API calls. Django commands will detect its presence and will make use of its services to color output just like on Unix-based platforms. colorama can be installed via pip:

Install ANSICON, a third-party tool that allows cmd.exe to process ANSI color codes. Django commands will detect its presence and will make use of its services to color output just like on Unix-based platforms.

Other modern terminal environments on Windows, that support terminal colors, but which are not automatically detected as supported by Django, may “fake” the installation of ANSICON by setting the appropriate environmental variable, ANSICON="on" .

Custom colors¶

The colors used for syntax highlighting can be customized. Django ships with three color palettes:

• dark , suited to terminals that show white text on a black background. This is the default palette.
• light , suited to terminals that show black text on a white background.
• nocolor , which disables syntax highlighting.

You select a palette by setting a DJANGO_COLORS environment variable to specify the palette you want to use. For example, to specify the light palette under a Unix or OS/X BASH shell, you would run the following at a command prompt:

You can also customize the colors that are used. Django specifies a number of roles in which color is used:

• error — A major error.
• notice — A minor error.
• success — A success.
• warning — A warning.
• sql_field — The name of a model field in SQL.
• sql_coltype — The type of a model field in SQL.
• sql_keyword — An SQL keyword.
• sql_table — The name of a model in SQL.
• http_info — A 1XX HTTP Informational server response.
• http_success — A 2XX HTTP Success server response.
• http_not_modified — A 304 HTTP Not Modified server response.
• http_redirect — A 3XX HTTP Redirect server response other than 304.
• http_not_found — A 404 HTTP Not Found server response.
• http_bad_request — A 4XX HTTP Bad Request server response other than 404.
• http_server_error — A 5XX HTTP Server Error response.
• migrate_heading — A heading in a migrations management command.
• migrate_label — A migration name.

Each of these roles can be assigned a specific foreground and background color, from the following list:

• black
• red
• green
• yellow
• blue
• magenta
• cyan
• white

Each of these colors can then be modified by using the following display options:

• bold
• underscore
• blink
• reverse
• conceal

A color specification follows one of the following patterns:

• role=fg
• role=fg/bg
• role=fg,option,option
• role=fg/bg,option,option

where role is the name of a valid color role, fg is the foreground color, bg is the background color and each option is one of the color modifying options. Multiple color specifications are then separated by a semicolon. For example:

would specify that errors be displayed using blinking yellow on blue, and notices displayed using magenta. All other color roles would be left uncolored.

Colors can also be specified by extending a base palette. If you put a palette name in a color specification, all the colors implied by that palette will be loaded. So:

would specify the use of all the colors in the light color palette, except for the colors for errors and notices which would be overridden as specified.

Bash completion¶

If you use the Bash shell, consider installing the Django bash completion script, which lives in extras/django_bash_completion in the Django source distribution. It enables tab-completion of django-admin and manage.py commands, so you can, for instance…

• Type django-admin .
• Press [TAB] to see all available options.
• Type sql , then [TAB], to see all available options whose names start with sql .

See How to create custom django-admin commands for how to add customized actions.

Black formatting¶

The Python files created by startproject , startapp , optimizemigration , makemigrations , and squashmigrations are formatted using the black command if it is present on your PATH .

If you have black globally installed, but do not wish it used for the current project, you can set the PATH explicitly:

For commands using stdout you can pipe the output to black if needed:

Running management commands from your code¶

To call a management command from code use call_command .

name the name of the command to call or a command object. Passing the name is preferred unless the object is required for testing. *args a list of arguments accepted by the command. Arguments are passed to the argument parser, so you can use the same style as you would on the command line. For example, call_command(‘flush’, ‘—verbosity=0’) . **options named options accepted on the command-line. Options are passed to the command without triggering the argument parser, which means you’ll need to pass the correct type. For example, call_command(‘flush’, verbosity=0) (zero must be an integer rather than a string).

Note that command options that take no arguments are passed as keywords with True or False , as you can see with the interactive option above.

Named arguments can be passed by using either one of the following syntaxes:

Some command options have different names when using call_command() instead of django-admin or manage.py . For example, django-admin createsuperuser —no-input translates to call_command(‘createsuperuser’, interactive=False) . To find what keyword argument name to use for call_command() , check the command’s source code for the dest argument passed to parser.add_argument() .

Command options which take multiple options are passed a list:

The return value of the call_command() function is the same as the return value of the handle() method of the command.

Output redirection¶

Note that you can redirect standard output and error streams as all commands support the stdout and stderr options. For example, you could write:
