AttributeError: 'NoneType' object has no attribute 'generated'

Describe the bug Can’t create a model with custom pk (id) data type (TextField).

Some part of pytest log:

def __init__(self, **kwargs) -> None:
        # self._meta is a very common attribute lookup, lets cache it.
        meta = self._meta
>       self._saved_in_db = meta.pk_attr in kwargs and meta.pk.generated
E       AttributeError: 'NoneType' object has no attribute 'generated'

To Reproduce

class UserModel(Model):
    id: str = fields.TextField(pk=True, generated=False)
    email: str = fields.CharField(index=True, unique=True, null=False, max_length=255)
    hashed_password: str = fields.CharField(null=False, max_length=255)
    is_active: bool = fields.BooleanField(default=True, null=False)
    is_superuser: bool = fields.BooleanField(default=False, null=False)

    class Meta:
        table = "user"

Expected behavior All work.

yes but it doesn’t take a generated value at all because it isn’t valid. it doesn’t want generated, true or false, because it can’t do anything with it. in the context of of a ``TextField´´ the concept of auto-generating values doesn’t exist, so it doesn’t accept configuration options for it as there is no point in accepting options it can’t do anything with

Released v0.15.6 with DeprecationWarning when using TextField as primary key with suggestion to use CharField instead.
