Question

大家好，我做了一个博客，但是当我删除帖子时，出现此错误，我使用的是Django最新版本：

TypeError at /post/(?P3\d+)/remove/
'str' object is not callable'

这是我的 Views.py

class PostDeleteView(LoginRequiredMixin,DeleteView):
    success_url = reverse_lazy('post_list')
    model = Post

这是我的应用程序 Urls.py

from django.urls import path
from blog import views

urlpatterns = [
    path('',views.PostListView.as_view(),name='post_list'),
    path('about/',views.AboutView.as_view(),name='about'),
    path('register/',views.user_register,name='user_register'),
    path('post/(?P<pk>\d+)',views.PostDetailView.as_view(),name='post_detail'),
    path('post/new/',views.CreatePostView.as_view(),name='post_new'),
    path('post/(?P<pk>\d+)/edit/',views.PostUpdateView.as_view(),name='post_edit'),
    path('post/<int:pk>/remove/',views.PostDeleteView.as_view(),name='post_remove'),
    path('drafts/',views.PostDraftListView.as_view(),name='post_draft_list'),
    path('post/(?P<pk>\d+)/comment/',views.add_comment_to_post,name='add_comment_to_post'),
    path('comment/(?P<pk>\d+)/approve/',views.comment_approve,name='comment_approve'),
    path('comment/(?P<pk>\d+)/remove/',views.comment_remove,name='comment_remove'),
    path('post/(?P<pk>\d+)/publish/',views.post_publish,name='post_publish'),
]

这是我的 post_confirm_delete.html

{% extends "blog/base.html" %}
{% block content %}
<form method="POST">
    {% csrf_token %}
    <p>Are You sure you want to delete {{ object }}?</p>
    <input type="submit" class="btn btn-danger" value="Confirm">
</form>
{% endblock %}

这是我的项目 Urls.py

您正在使用带有正则表达式的路径，而不是它的工作方式docs，只能将带有正则表达式的url字符串与re_path一起使用

应该是：

path('post/<int:pk>/remove/',views.PostDeleteView.as_view(),name='post_remove'),
