Best way of using virtualenv, Django and PyCharm

Hello Mathieu,

The way it's supposed to work is the following:

- django_settings.py is needed to override the TEST_RUNNER setting and to

hook PyCharm's graphical test runner into the Django testing system

- django_settings.py imports your actual Django settings module. You can

tell it which one to import by filling the "Settings file" field in the Django

tests run configuration. By default, it tries to import module 'settings'.

- the working directory can also be specified in the Django tests run configuration.

Hope this helps.

I've just bought PyCharm for my Django-based projects, and having

participated in the beta test program, I am looking forward to keep on

using this excellent IDE.

But, during the beta-phase, I was not using virtualenv based projects.

Now I am, and I'm running into troubles for my unit tests. I can't

figure out how to configure it all correctly, for the unit testing to

run as it should.

Already from the start, it appears "C:\Program Files

(x86)\JetBrains\PyCharm 1.1\helpers\pycharm\django_manage.py" is being

run as the "manage.py" script, whereas it would be more logical should

this be the manage.py from my project's directory.

Also, the tests aren't run in my project's directory, which gives "App

with label app_name could not be found".

Next to that, I have different settings (dev, acc, prd) inside a

settings directory. I can load these when invoking manage.py from the

command line, but I can't seem to find a way for PyCharm to take them

into account (instead, I see "pycharm django settings imported", which

is of course not what I want).

I have the impression that the "only" virtualenv support there is, is

the possibility to select the virtualenv-specific python interpreter.

Has anyone succeeded in setting up tests (or more globally: use

manage.py as it would from the command line with virtualenv activated)

within a virtualenv environment?

I should say I'm primarily working on Windows 7 (which complicates

matters further, I'm sure).

Thanks in advance!

(PS: The text editor for creating posts doesn't work as it should on

Opera 10).

Thanks for clarifying that bit.

I still can't load my specific settings though; could it be that the path is not added when loading them?

The directory structure is as follows:

apps/

    app1

    app2

    ...

    settings/

        __init__.py

        common.py

        development.py

        ...

Even when pointing the test runner config to c:/(...)/apps/settings/development.py, these settings are not loaded.

The workaround I'm using now is through  Python run commmands (manage.py test, etcetera), but of course this way I lose the nice test integration :-)

Hello Mathieu,

You can edit django_settings.py and print out the value of settings_file

to see what exactly is being imported. The code does support specifying the

path to a settings file in a subdirectory.

It still seems my settings aren't being loaded correctly. django_settings.py reports that they are (see the traceback, below), but debugging a django test run points out that settings.INSTALLED_APPS is an empty list (which it isn't when running manage.py test items from the shell - that works fine).

Here's the traceback:

Hi, was this post ever resolved? It seems as though this is still an issue.

I am running into a similiar issue with this test tool.  It seems to ignore my django version and everything, as the error that I am getting when using the test runner is below.  This is the same error that I get when trying to run the newer django 1.4 on my site instead of the specified django version.

Hi Michael,

Sorry, I didn't understand your issue. Pycharm uses Django from interpreter configured in Settings->Project Interpreter.

I am running into this issue as well 10 years down the road. However, it doesn't look like it was rectified.  Everything works fine when I run manage.py test in the shell.  When I go to run a Django test with Environment viariable set to DJANGO_SETTINGS_MODULE=app.settings I still get the following error:

raise ImproperlyConfigured("settings.DATABASES is improperly configured. "
django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

settings.py file is as follows:

INSTALLED_APPS = [
    'django.contrib.admin',     
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'graphene_django',
    'app.apps.AppConfig',
]
