DeleteView 不删除，只是刷新删除页面

Question

当我点击我的删除项目链接时，它会将我带到我的删除页面，并点击一个按钮来删除项目的模型数据，然后将我带到个人资料页面。但是，当我单击删除按钮时，页面只是刷新并且没有数据被删除？！ 我在这里做错了什么？任何帮助将不胜感激:-)

class DeleteProject(UpdateView):

    template_name = 'howdidu/delete_project.html'

    def get_object(self, queryset=None):
        obj = super(DeleteProject, self).get_object()
        if not obj.user == self.request.user:
            raise Http404
        return obj

    def get_success_url(self):
        project_username = self.request.user.username
        #project_slug = self.object.slug
        return reverse('user_profile', kwargs={'username':project_username})

delete_project.html 模板

{% extends 'howdidu/base.html' %}

{% load staticfiles %}

{% block title %}Delete project{% endblock %}

{% block body_block %}

        <h1>Delete project</h1>

        <form method="post">{% csrf_token %}
        <p>Are you sure you want to delete "{{ userproject.title }}"?</p>
        <input type="submit" value="Confirm" />
        </form>

{% endblock %}

网址

urlpatterns = patterns('',
        url(r'^$', views.index, name='index'),
        url(r'^register_profile/$', views.register_profile, name='register_profile'),
        url(r'^update_profile/$', views.update_profile, name='update_profile'),

带有删除链接的Project.html模板

{% extends 'howdidu/base.html' %}

{% load staticfiles %}

{% block title %}Project{% endblock %}

{% block body_block %}

        {% if project %}

        <h1>{{ project.title }}</h1>
        <img src="{{ project.project_picture.url }}" width = "300" height = "300"  />
        <h3>{{ project.project_overview }}</h3>
        {% if user.is_authenticated %}
        {% if project_user.username == user.username %}
        <p><a href="{% url 'update_project' project_user.username project.slug %}">Edit project</a></p>
        <p><a href="{% url 'delete_project' project_user.username project.slug %}">Delete project</a></p>
        {% endif %}
        {% endif %}


        {% else %}
            The specified project {{ project.title }} does not exist!
        {% endif %}

{% endblock %}

您必须使用 DeleteView 而不是 UpdateView。 See here.
