Error importing plugin 'mypy_django_plugin.main'

(As per #160, I’m forking a dedicated issue for this.)

I’m using mypy 0.720 with django-stubs 1.1.0 (from PyPI today):

$ mypy --version
mypy 0.720
$ pip show django-stubs
Name: django-stubs
Version: 1.1.0

With plugins = mypy_django_plugin.main in mypy.ini, mypy fails as follows:

mypy -p foo.bar
../mypy.ini:12: error: Error importing plugin 'mypy_django_plugin.main'

even though mypy_django_plugin loads just fine.

I’ve tried dropping .main from the mypy.ini and that gives:

../mypy.ini:12: error: Plugin 'mypy_django_plugin' does not define entry point function "plugin"

I’ve also tried replacing .main with :main (which seems to be the current recommended way to specify entry points in mypy.ini) and that gives:

../mypy.ini:12: error: Plugin 'mypy_django_plugin' does not define entry point function "main"

was facing the same issue, but placing [mypy.plugins.django-stubs] before setting plugins in setup.cfg fixed it for me.

I’m able to repro this in Django v2 as well.

This happens at module import time, before the DjangoContext gets initialized (and sets up django). A hacky fix is to move the ArrayField import block inside the DjangoContext.__init__ func after the initialize_django call. This works because the class is only referenced inside an instantiated version of the class. Although I admit, this is not a viable long-term solution.

An example of this is here: https://github.com/typeddjango/django-stubs/compare/master...sklarsa:issue-166
