未找到带有参数 '('',)' 的 'delete_post' 的反向操作。尝试了 1 种模式：['article/(?P<pk>[0-9]+)/remove$']

Question

enter image description herei 正在创建一个简单的博客站点，我创建了 delete7edit 按钮，但是当我尝试重置应用程序并转到那里时，我得到了这个错误（标题）

这是我的代码view.py：

from django.views.generic import ListView
from . models import Article
from django.views.generic import ListView, DetailView, CreateView, UpdateView, 
DeleteView
from .forms import PostForm, EditForm
from django.urls import reverse_lazy



class ArticleListView(ListView):
    model = Article
    template_name = 'home.html'


class ArticleDetailView(DetailView):
    model = Article
    template_name = 'detail.html'


class AddPostView(CreateView):
    model = Article
    form_class = PostForm
    template_name = 'add_post.html'
    #fields = '__all__'
    #fields = ('title', 'body')


class UpdatePostView(UpdateView):
    model = Article
    form_class = EditForm
    template_name = 'update_post.html'
    #fields = ['title', 'title_tag', 'body']


class DeletePostView(DeleteView):
    model = Article
    template_name = 'delete_post.html'
    success_url = reverse_lazy('home')

urls.py:

from django.urls import path
from . import views

urlpatterns = [
    path('', views.ArticleListView.as_view(), name='home'),
    path('article/<int:pk>', views.ArticleDetailView.as_view(), name='detail'),
    path('add_post/', views.AddPostView.as_view(), name='add_post'),
    path('article/edit/<int:pk>', views.UpdatePostView.as_view(), name='update_post'),
    path('article/<int:pk>/remove', views.DeletePostView.as_view(), name='delete_post'),
]

模板 delete_post.html：

{% extends 'base.html' %}
{% block title %}Delete Blog Post{% endblock %}
{% block content %}


<h1>Delete Post...</h1>
<br/><br/>
<hr3>Delete: {{ post.title }}</hr3>

<br/>
<div class="mb-3">
    <form method="POST">{% csrf_token %}
        <strong>Are you sure?</strong><br/><br/>
         <button class="btn btn-secondary">Delete Post!</button>
</div>


{% endblock %}

模板 update_post.html：

{% extends 'base.html' %}
{% block title %}Edit Blog Post{% endblock %}
{% block content %}


<h1>Update Post...</h1>
<br/><br/>
<div class="mb-3">
    <form method="POST">{% csrf_token %}
        {{ form.as_p }}
        <button class="btn btn-secondary">Update</button>
</div>


{% endblock %}

请帮帮我，我是 django 的新手，我还不知道 ----------------------------- ------------------------------

您的删除网址 article/<int:pk>/remove 但我在图片中看到您输入了 article/1/。

path('article/<int:pk>/remove', views.DeletePostView.as_view(), name='delete_post')

你需要输入article/1/remove。
