Root Cause

Using a field name in filter() or exclude() that does not exist on the model.

generic

中文

在filter()或exclude()中使用模型上不存在的字段名。

Workarounds

  1. 95% success 
    Check model fields and use correct field name: MyModel.objects.filter(actual_field=value)
  2. 90% success 
    Use double underscore to traverse relationships: MyModel.objects.filter(related__field=value)

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Doesn't fix the root cause; the queryset still fails when executed.

  2. 70% fail

    Loses functionality and may return incorrect data.
