Root Cause

Attempting to filter or order by a field that doesn't exist on the model.

generic

中文

尝试按模型中不存在的字段进行过滤或排序。

Workarounds

  1. 90% success 
    Add the field to model: published_year = models.IntegerField() and run migrations.
  2. 95% success 
    Use correct existing field: published_date__year for filtering by year.

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Adding a property named published_year to model doesn't make it queryable.

  2. 50% fail

    Using annotate with wrong name still raises FieldDoesNotExist.
