根因分析

ORM 模型定义了数据库中不存在的列，或表结构已过时。

English

The ORM model defines a column that does not exist in the database table, or the table schema is outdated.

generic

解决方案

  1. 95% 成功率 Use Alembic migrations to add the column 
    alembic revision --autogenerate -m "add age column"
alembic upgrade head
  2. 85% 成功率 Drop and recreate the table if in development 
    Base.metadata.drop_all(engine)
Base.metadata.create_all(engine)

无效尝试

常见但无效的做法:

  1. Adding the column manually via raw SQL without updating the model 65% 失败

    The model may still reference the old schema if not refreshed.

  2. Ignoring the error and assuming it's transient 100% 失败

    The error will persist until the schema is updated.
