Root Cause

Attempting to filter by a non-existent field name, maybe due to wrong related field access.

generic

中文

尝试按不存在的字段名过滤，可能是由于错误的相关字段访问。

Workarounds

  1. 95% success 
    Use correct related field: Book.objects.filter(author__name='John') if Author has name field.
  2. 90% success 
    Check model fields and use exact field names: author.name if author is FK.

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Using author__name instead of author__name__icontains still fails if field doesn't exist.

  2. 80% fail

    Adding a property to model doesn't make it queryable in ORM.
