`Tag` breaking in Django 4.1 when registering without the `name` kwarg about django-classy-tags

[kevinmarsh]

Just getting back to this, think actually we might not even need if django_lt_41, might just be able to modify the name param for the metaclass

- return super().__new__(cls, name, bases, attrs)
+ return super().__new__(cls, tag_name, bases, attrs)

If you merge #85 I'll push a PR on top of that which passes on Django 2.2-4.1 (and main branch) and can discuss implementation more there (as there are drawbacks to that potentially unavoidable approach)

@kevinmarsh Thanks for raising. I've not made it to 4.0 yet so a long way from catching this one.

If I've understood this correctly, we could do something to check if django<4.1 and vary the attribute set;

    def __new__(cls, name, bases, attrs): 
        parents = [base for base in bases if isinstance(base, TagMeta)] 
        if not parents: 
            return super().__new__(cls, name, bases, attrs) 
        tag_name = str(attrs.get('name', get_default_name(name))) 
  
        if django_lt_41:

            def fake_func(): 
                pass  # pragma: no cover 
  
            fake_func.__name__ = tag_name 
            attrs['_decorated_function'] = fake_func 

        else:
            attrs['__name__'] = tag_name

@kevinmarsh I've merged #85 (sorry for the delay!)

In terms of moving forward with this, I'm more than happy to drop Django 2.2 as its no longer supported.
