我有多个待办事项列表，每个待办事项列表都有列表项。列表项模型中有一个已完成的字段。如果列表项已由登录用户完成，当我放置一个要处理的表单时，我在详细信息页面中收到此错误。
我得到的错误是：
NoReverseMatch at /detail/3/

我知道错误来自 url 中引用的主键，但我不知道到底是什么导致了错误
我的观点.py:

datail.html 模板中的我的表单标签：
<form method="POST" action="{% url 'completed_list_item' todo_list.list_pk item.item_pk %}">
这是 urls.py:
path('detail/<int:pk>/', views.detail, name='detail'),
path('completed-item/<int:list_pk>/<int:item_pk>/', views.completed_list_item, name='completed_list_item'),
