Root Cause

Trying to filter on a related model field without proper double underscore syntax.

generic

中文

尝试在关联模型字段上过滤，但没有使用正确的双下划线语法。

Workarounds

  1. 95% success 
    Use correct syntax: Model.objects.filter(related_model__field='value')

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Django requires double underscore for traversing relations.

  2. 50% fail

    Doesn't allow database-level filtering, only Python-side.
