Root Cause

The related_name in ForeignKey conflicts with an existing field or is invalid.

generic

中文

ForeignKey 中的 related_name 与现有字段冲突或无效。

Workarounds

  1. 95% success 
    Set a unique related_name: author = models.ForeignKey(Author, related_name='books')
  2. 85% success 
    Use related_query_name to avoid conflict: related_query_name='author'

Dead Ends

Common approaches that don't work:

  1. 50% fail

    Removing related_name doesn't fix if the default related name conflicts.

  2. 30% fail

    Changing the model name in settings doesn't resolve the relationship.
