`model.Meta` is unrecognized in the latest version

[tylerlaprade]

I did not have this problem in 0.19.1. After upgrading to 0.20.0, the below code errors on model.Meta

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from django.db.models import Model

def foo(model: type['Model']):
    model.Meta    # Cannot access attribute "Meta" for class "type[Model]". Attribute "Meta" is unknownPylance[reportAttributeAccessIssue]

It was intentionally removed in #215.

There is lots of nuanced discussion in the equivalent django-stubs change. Recommend looking at the issues which mention that pull request too.

Hmm, I'm not sure what the best path forward is for me, then. I read through the linked discussion and issues, but didn't find any way to handle my situation. Here is the actual usecase for why I need it generically on Model:

def create_proxy_model(
    model: type['Model'],
    new_model_name: str | None = None,
    meta_updates: dict[str, str] | None = None,
) -> type['Model']:
    if new_model_name is None:
        new_model_name = f'{model.__name__}SoftDeleted'

    if meta_updates is None:
        meta_updates = {
            'verbose_name': f'{model._meta.verbose_name} [Soft Deleted]',
            'verbose_name_plural': f'{model._meta.verbose_name_plural} [Soft Deleted]',
        }

    class NewMeta(model.Meta):
        proxy = True
        managed = False

    for key, value in meta_updates.items():
        setattr(NewMeta, key, value)

    return types.new_class(
        new_model_name,
        (model,),
        {},
        lambda ns: ns.update({'Meta': NewMeta, '__module__': model.__module__}),
    )
