Re: how to get a list of all installed applications

Have a look in django/db/models/loading.py . There are a number of
useful methods in there. In particular, get_apps(), which contrary to
what you claim above, should give you all installed apps, not installed
models (you use get_models(app_name) to get all the models for an app).

Hello, this is a very old post but seeing how I got here from a Google search I figure someone else might also. Looking at get_apps() this is what I get:

from django.db.models import loading
    for mod in loading.get_apps():
        print(mod.__name__)

And the output:

django.contrib.auth.models
django.contrib.contenttypes.models
django.contrib.sessions.models
django.contrib.sites.models
django.contrib.messages.models
django.contrib.staticfiles.models
django.contrib.admin.models
django.contrib.admindocs.models
debug_toolbar.models
django_extensions.models
solo.models
wp_user_agents.models
home.models
projects.models
# <...plus all of my other app's models...>

So you see, get_apps() does return the models, not the apps themselves.

However, I did find this that works:

from django.conf import settings
from django.utils.module_loading import import_module
apps = []
for appname in settings.INSTALLED_APPS:
    apps.append(import_module(appname))

Or to shorten it:

from django.conf import settings
from django.utils.module_loading import import_module
apps = [import_module(appname) for appname in settings.INSTALLED_APPS]

I needed it to design a search app for my site. If anyone has a better way I would really like to hear about it (no sarcasm).
