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。

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

解决方案

  1. 90% 成功率 
    # 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% 成功率 
    from app.models import User as UserModel
# Use UserModel in code

无效尝试

常见但无效的做法:

  1. 70% 失败

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

  2. 80% 失败

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