ModelSchema Field in fields list and model representation

[pinguin999]

class AuthorSchema(ModelSchema):
    if TYPE_CHECKING:
        id: int
        name: str
        role: str
        image: str

    class Meta:
        model = Author
        fields = ["id", "name", "role", "image"]


class TipSchema(ModelSchema):
    if TYPE_CHECKING:
        id: int
        name: str
        text: str

    author: AuthorSchema

    class Meta:
        model = Tip
        fields = ["id", "name", "text", "author"]

In this Code author is in author: AuthorSchema and in the fields list.
What is the expected behaviour? Returning the id or an object to type AuthorSchema?

Maybe the checker could raise an error that this configuration is not allowed.

expected is that attribute defined on class will overwrite meta.fields

The general rule is that all fields that in meta are created automtically - and then the rest of the fields defined by user

but yeah - makes sense to throw some validation error as some can just loose this and get unexpected behaviour
