I'm settings up a Django project following the structure of this cookiecutter template but I'm having problems with explicit relative imports in my apps.

I'm trying to import my models using from .model import ModelA but I'm getting this error from Django:

RuntimeError: Model class core.models.ModelA doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

My project is structured like this:

my_project

  - config

    - __init__.py

    - settings.py

    - urls.py

  - my_project

    - __init__.py

    - core # this is an app

      - __init__.py

      - models.py

      # remaining app files

  manage.py

I have of course put my app in INSTALLED_APPS:

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'rest_framework',

    'my_projects.core.apps.CoreConfig', # my app

]

And CoreConfig is setup as:

class CoreConfig(AppConfig):

    name = 'my_project.core'

It feels like django is not loading the AppConfig when using explicit relative import.

Everything works perfectly if I change my imports to absolute paths from my_project.core.models import ModelA

What am I missing?

EDIT 1:

Might also be worth mentioning that I've added a few rows to my manage.py (as in the cookiecutter template) for adding the my_project directory to the sys.path.

from django.conf import settings

sys.path.append(os.path.join(settings.ROOT_DIR, 'my_project'))

When append urls in config.urls, you should use my_projects.core.urls instead of core.urls. for example:

urlpatterns = [

    ...



    # Your stuff: custom urls includes go here

    path("my_projects/", include("my_projects.core.urls", namespace="my_projects")),

] + static(

    settings.MEDIA_URL, document_root=settings.MEDIA_ROOT

)
