.. _configuring_django_settings:
Configuring Django settings
===========================
There are a couple of different ways Django settings can be provided for
the tests.
The environment variable ``DJANGO_SETTINGS_MODULE``
---------------------------------------------------
Running the tests with DJANGO_SETTINGS_MODULE defined will find the
Django settings the same way Django does by default.
Example::
$ export DJANGO_SETTINGS_MODULE=test_settings
$ py.test
or::
$ DJANGO_SETTINGS_MODULE=test_settings py.test
Command line option ``--ds=SETTINGS``
-------------------------------------
Example::
$ py.test --ds=test_settings
pytest.ini settings
-------------------
Example contents of pytest.ini::
[pytest]
DJANGO_SETTINGS_MODULE = test_settings
Order of choosing settings
--------------------------
If `--ds`, the environment variable and the pytest.ini configuration is used at
the same time, pytest-django will first prefer using settings from the command
line option `--ds`, then the environment variable and last the pytest.ini.
Using django-configurations
---------------------------
There is support for using `django-configurations <https://pypi.python.org/pypi/django-configurations/>`_.
To do so configure the settings class using an environment variable, the --dc
flag, or pytest.ini DJANGO_CONFIGURATION.
Environment Variable::
$ export DJANGO_CONFIGURATION=MySettings
$ py.test
Command Line Option::
$ py.test --dc=MySettings
INI File Contents::
[pytest]
DJANGO_CONFIGURATION=MySettings
Using ``django.conf.settings.configure()``
------------------------------------------
Django settings can be set up by calling ``django.conf.settings.configure()``.
This can be done from your project's ``conftest.py`` file::
from django.conf import settings
def pytest_configure():
settings.configure(DATABASES=...)
