Type check fails with:

plugins/auth/fps_auth/db.py:33: error: Incompatible types in assignment (expression has type "Column[str]", base class "SQLAlchemyBaseUserTable" defined the type as "str")  [assignment]

It's pointing to this line where email is defined:

class User(SQLAlchemyBaseUserTableUUID, Base):
    anonymous = Column(Boolean, default=True, nullable=False)
    email = Column(String(length=32), nullable=False, unique=True)
   ...

It seems to be an SQLAlchemy issue, but maybe @frankie567 has an idea?

[frankie567]

Why do you need to redefine the email column? It's directly provided by SQLAlchemyBaseUserTableUUID (besides 32 characters is probably too short). That's why there is a type mismatch between the two.

[davidbrochart]

Ah right, it was not necessary. Thanks!

@frankie567 I had weird errors when accessing User.oauth_accounts, defined here:

sqlalchemy.exc.MissingGreenlet: greenlet_spawn has not been called; can't call await_only() here. Was IO attempted in an unexpected place? (Background on this error at: https://sqlalche.me/e/20/xd2s)

It was caused by a MissingGreenlet. After making the recommended changes in 9fced2b it works fine.
Do you think it's the right thing?

[frankie567]

Well, TIL about AsyncAttrs. Looks nice!

However, if you have lazy="joined" on the relationship arguments, oauth accounts should be loaded eagerly up-front, so you shouldn't have this error 🤔

Mmm then I'm not sure what was going on, I might have to revisit this issue in the future.
