当我在 Django 中输入 change_list 时不可散列类型 'list'
unhashable type 'list' when i enter on change_list in Django
我搜索了几天来解决这个问题。在接触 admin.py 文件以覆盖 get_queryset 和 get_form 方法后，我 运行 进入不可散列类型 'list' 错误，其中没有关于错误位置的信息位于。我删除了 get_queryset 和 get_form 方法的覆盖，但我仍然得到相同的结果。
[错误]
TypeError：无法散列的类型：'list'
当我想通过覆盖 get_queryset 方法来过滤列表时，或者当我尝试输入表单列表的元素时，我发现了这个错误。

TypeError: unhashable type: 'list'
如有任何帮助，我们将不胜感激。谢谢。
在深入研究问题后，错误是在 html 模板的条件只读字段内的模型表单中生成的。该错误特别出现在 fieldsets.html 文件的 {{field.contents}} 中。
此问题是由于用户分配到的组中缺少权限而产生的。添加该权限后，错误消失了。
我搜索了几天来解决这个问题。在接触 admin.py 文件以覆盖 get_queryset 和 get_form 方法后，我 运行 进入不可散列类型 'list' 错误，其中没有关于错误位置的信息位于。我删除了 get_queryset 和 get_form 方法的覆盖，但我仍然得到相同的结果。

如有任何帮助，我们将不胜感激。谢谢。
在深入研究问题后，错误是在 html 模板的条件只读字段内的模型表单中生成的。该错误特别出现在 fieldsets.html 文件的 {{field.contents}} 中。 此问题是由于用户分配到的组中缺少权限而产生的。添加该权限后，错误消失了。
