Mypy Support For TaggableManager

[jmichalicek]

I have a model with a TaggableManager for a model with direct foreign keys defined, per the docs:

class TaggedRecipe(TaggedItemBase):
    content_object = models.ForeignKey("Recipe", on_delete=models.CASCADE)

    def __str__(self) -> str:
        return f"{self.content_object}: {self.tag}"

and then on the Recipe model:

tags = TaggableManager(through=TaggedRecipe)

When running mypy, I get an error about that line error: Couldn't resolve related manager for relation 'tagged_recipes' with the actual error being [django-manager-missing]

This is with the following versions:
Django 5.0.6
django-taggit 5.0.1
mypy 1.10.1
django-stubs 5.0.2
django-stubs-ext 5.0.2

I guess that's from the mypy django plugin? Will need to look at into if we can get it to play nicely with django-taggit. Thanks for the clear report!

This looks related to typeddjango/django-stubs#1023

From what I could gather, it seems like adding typing information to django-taggit could fix the issue, but I'm not sure.

That said, even if it didn't fix that specific issue, it would be nice to have django-taggit typed.
