ORM Model register failed

[wadehehe]

Base._decl_class_registry can not find a key 'tablename'

What reason cause this?

I have already inherit BaseModel

[asif-mahmud]

did you declare __tablename__ in your model class ? if not that should be the reason.

[asif-mahmud]

BTW, you should utilize db.ModelBase for database models, it handles the tablename internally. check the source in instance/db.py -> ModelBase

[wadehehe]

Yes I declare it. I think i have resolved it , ModelBase should inherit Sqlalchemy Model not Object.

[asif-mahmud]

sorry, i had to recheck my own reply, its in the git's readme file - you have to use instance.db.Base as your model's base. that will do.

Thanks ,I also try with instance.db.Base ,but it also not working.
I think _decl_class_registry is sqlalchemy attribute, so we must use it as ModelBase's base.

[asif-mahmud]

no no, you have to use `db.Base` not the `ModelBase`. Best wishes - Asif Mahmud Shimon
