Root Cause

ORM查询中使用了不存在的字段名，或关联查询语法错误

generic

中文

查询时引用了模型不存在的字段，通常因为拼写错误或关联名称错误

Workarounds

  1. 90% success 
    使用Article.objects.filter(author__name='John')代替author_id
  2. 85% success 
    Article.objects.filter(author__id=1)

Dead Ends

Common approaches that don't work:

  1. 80% fail

    数据库表结构未更新，查询仍会失败

  2. 50% fail

    语法正确但逻辑错误，会查询关联对象的主键而非外键字段
