Django get list of models in application

From Django 1.7 on, you can use this code, for example in your admin.py to register all models:

from django.apps import apps
from django.contrib import admin
from django.contrib.admin.sites import AlreadyRegistered

app_models = apps.get_app_config('my_app').get_models()
for model in app_models:
    try:
        admin.site.register(model)
    except AlreadyRegistered:
        pass
