Question

为什么我收到此错误

执行doInBackground（）
时发生错误

我哪里错了？ LogCat如下所示

这是 LoginActivity.java

django.core.exceptions.FieldError: Auto-generated field 'parentmodel_ptr' in class 'ChildModel' for parent_link to base class 'ParentModel' clashes with declared field of the same name.

我没有在doInBackGround函数中执行任何UI工作，但我仍然遇到此错误。

logcat的：
