我已经提到了这个question并升级了django和djangorestframework，但它们似乎都不起作用。我是django的新手。请询问我可以提供的更多信息。请指导我解决错误。

Answer 1

当然，升级DRF不能解决您的问题，因为该问题与DRF无关-它在InheritanceManager代码中，该代码来自django-models-utils和is a dependance of django-users-2。还有FWIW，the issue has been fixed 2 years ago，所以您的django-models-utils版本可能已经过时了。

请注意，您需要自己进行调试的所有工作是：1 /阅读回溯以找出问题发生的位置，2 /转到项目的gitlab，3 /搜索错误消息（或它-我在问题跟踪器中搜索了“ get_all_related_objects”）（也搜索了已解决的问题），4 /阅读了问题的描述，状态和解决方案。

“选项”对象没有属性“ get_all_related_objects”
