Description
Let's say I have a ModelSchema:

class UserSchema(ModelSchema):
    password: SecretStr

    class Meta:
        model = User
        fields = ["username", "password"]

What django-ninja does, in ModelSchemaMetaclass.__new__ is:

custom_fields = []
annotations = namespace.get("__annotations__", {})
for attr_name, type in annotations.items():
    ...
    custom_fields.append((attr_name, type, default))

However, in Python 3.14, namespace will not have __annotations__, it will have an __annotate_func.

So in Python 3.14, custom_fields == [] after that loop.

I'm unsure what the "best practice" is for this, what we're supposed to do. But I've seen an least one other library doing:

ann = annotationlib.get_annotate_from_class_namespace(namespace)
annotations = annotationlib.call_annotate_function(
    ann, format=annotationlib.Format.VALUE
) if ann else {}

cf.: stdlib:annotationlib
