How to migrate from rx.Model to sqlmodel.SQLModel

I saw in the release notes of 0.8.15 that sqlmodel.SQLModel is now recommended over rx.Model.
Is there some documentation somewhere on how to actually do that? The documentation on reflex.dev still uses rx.Model.
I made an attempt based on the release notes and deprecation warning I was getting and tried the following:

• old:

  class Foo(rx.Model, table=True): ...
  

• new:

  @rx.ModelRegistry.register
  class ExerciseTagLink(SQLModel): ...
  

But this doesn't seem to be right, as running db makemigrations now just results in all tables being dropped.

When migrating to Reflex 0.8.15 I just replaced the base class as in class Foo(rx.Model, table=True) ==> class Foo(SQLModel, table=True) and things just worked. I don't know if table=True is still necessary, haven't tried yet removing it. And I did not add the decorator @rx.ModelRegistry.register though as in your example.

Thanks a lot, I gave it a try and it worked for me as well like this. The table=True still seems to be needed, at least I got an error from reflex db makemigrations when I removed it.

Great, thanks for letting me know!
