AstroidImportError when ForeignKey points to app not in root module

[federicobond]

I have a project structure where Django apps live in an apps/ directory. This makes the import path for a model at apps.myapp.models.MyModel.

When pylint_django processes the ForeignKey, it tries to load myapp.models, resulting in an astroid.exceptions.AstroidImportError. The only way around it as I see is to actually read the contents of INSTALLED_APPS settings variable.

I'm seeing the same issue but there's no reliable way to get this information from Django's INSTALLED_APPS. Applications can define an AppConfig class and have a name different from their actual Python module. On top of this Django requires the format for foreign keys to be "app_name.ModelName" and you can't have dots in the app_name while I have a project where AppConfig uses dots in the app_name.

The solution is to modify the PYTHONPATH variable and instruct pylint where to find these additional modules:

$ PYTHONPATH=~/Kiwi/tcms/ pylint --load-plugins pylint_django tcms/testplans/models.py

My ForeignKey relations look like ForeignKey('management.Tag') while the module is tcms.management.models
