Comment (by julien):
A discussion came about on the user-list about this:
http://groups.google.com/group/django-
users/browse_thread/thread/559aa0a2d074a7b5
I wrote a patch based on Russell's feedback. The proposed API is as
follows:
{{{
class MyMetaTest(TestCase):
installed_apps = ['fakeapp','otherapp']
extra_apps = ('yetanotherapp',)
def test_stuff(self):
...
}}}
* `installed_apps` and `extra_apps` can either be tuple or a list. They
can coexist or be used individually.
* `installed_apps` overrides the settings INSTALLED_APPS.
* `extra_apps` adds the given apps either to INSTALLED_APPS or to
`installed_apps` if it also exists.
Now, responding specifically to Russell's remarks:
"Obviously, the test applications need to be:
1. Added to INSTALLED APPS and the app cache on startup
2. Installed in the app cache before the syncdb caused by the pre-test
database flush takes effect. You shouldn't need to manually invoke syncdb.
3. Removed from INSTALLED_APPS and the app cache on teardown"
My answers below:
1. Done
2. Done, but I think `syncdb` still needs to be invoked to create the
extra tables, otherwise `flush` will raise an exception saying it cannot
find those tables.
3. INSTALLED_APPS is properly restored, but I could not find a way to
unload the apps from the cache. Should an extra method be written in the
AppStore class (`unload_app()` and/or `unregister_models()`)?
