Original Pull Request: https://github.com/langgenius/dify/pull/24747

State: closed
Merged: Yes

Fixes #24746

The current copy implementation is problematic: it explicitly sets id=self.id when creating a new AppModelConfig. Since id is the primary key, this will inevitably cause a primary key conflict and trigger a database error. Considering that the copy function is not used anywhere, it’s safer to remove it entirely.

If we want to keep this function, we should remove id=self.id so that a new ID is automatically generated by server_default=uuid_generate_v4().
