UUID does not set 'pkname'

[yudjinn]

I have the following setup:
models
├─base.py
├─user.py
└─item.py

Base is defined as such:
`
class BaseMeta(ormar.ModelMeta):
database = database
metadata = metadata

class Base(ormar.Model, DateFieldsMixins):
class Meta(BaseMeta):
abstract = True

id: UUID4 = ormar.UUID(primary_key=True, default=uuid.uuid4)

User: class User(Base):
class Meta:
abstract = True
tablename = "users"

username: str = ormar.String(max_length=50, unique=True, index=True)
is_active: bool = ormar.Boolean(default=True)

class UserDB(User):
hashed_password: str = ormar.String(max_length=256)
and Item:
class Item(Base):
class Meta:
tablename = "items"

name: str = ormar.String(max_length=50, unique=True, index=True)
owner: Optional[Union[User, Dict]] = ormar.ForeignKey(
    UserDB,
    related_name="items",
)

`

when running alembic revision --autogenerate -m "init" I get:
AttributeError: type object 'Meta' has no attribute 'pkname' from ormar/fields/foreign_key.py:114

I'm guessing the UUID column does not set the primary key attribute on the meta class? The docs didnt seem to answer how to handle mutli-file models so I may have missed something.

Also, do you have to redefine Meta in EVERY class definition? I was hoping to extend the Base class and have the database etc be inherited

Hi @yudjinn
This Problem you mentioned has nothing to do with UUID and I suggest you read this best practice for Meta class and also read this section for document type of inheritance.

Your Code was a bit messy and I couldn't read it well, but if you like it, I have a project in this link where you can look at how to define models and inheritance and their relationship with each other. I hope it will be useful and useful to you.
