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。

English

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

generic

解决方案

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

无效尝试

常见但无效的做法:

  1. 60% 失败

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

  2. 80% 失败

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