Root Cause

Two different classes with the same name are registered in the same declarative base, often due to duplicate imports or class name collisions.

generic

中文

在同一个声明式基类中注册了两个同名类，通常由于重复导入或类名冲突。

Workarounds

  1. 90% success 
    # Use from app.models.user import User consistently
from app.models.user import User
# Avoid: from app.models import User if it's defined elsewhere
  2. 85% success 
    from app.models import User as UserModel
# Use UserModel in code

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Breaks existing references to the original class name in other parts of the code.

  2. 80% fail

    Causes ambiguity in relationship resolution and can lead to unexpected behavior.
