Question

上周我开始使用Python和Django进行编码，现在我开始对此感到绝望。我必须处理待办事项列表，并希望通过单击任务旁边的按钮来删除ToDo任务。现在我总是得到一个

NoReverseMatch at / delete / 1

错误：（

delete_confirm.html：

{% extends "base_page.html" %}

{% block title %}Confirm Todo delete{% endblock %}

{% block content %}
<form action="" method="post">{% csrf_token %}
    <p>Are you sure you want to delete "{{ object }}"?</p>
    <input type="submit" value="Confirm" />
</form>

{% endblock %}

我的Urls.py：

from django.conf.urls import patterns, url
from todolist import views

urlpatterns = patterns('',
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^add', views.AddView.as_view(), name='add'),
    url(r'^impressum', views.ImpressumView.as_view(), name='impressum'),
    url(r'^edit/(?P<pk>\d+)$', views.UpdateView.as_view(), name='todo_edit'),
    url(r'^delete/(?P<pk>\d+)', views.DeleteView.as_view(), name='todo_delete'), 
)

views.py:

from django.shortcuts import render
from django.core.urlresolvers import reverse_lazy
from django.http import HttpResponse
from django.views import generic
from django.views.generic import TemplateView, ListView, CreateView, UpdateView, DeleteView
from todolist.models import Todo

# Create your views here.
class IndexView(ListView):
    template_name = 'index.html'
    model = Todo

class ImpressumView(TemplateView):
    template_name = 'impressum.html'

class AddView(CreateView):
    template_name = 'add.html'
    model = Todo
    fields = ['title','deadline','progress']
    success_url = '/'

class UpdateView(UpdateView):
    template_name = 'edit.html'
    model = Todo
    fields = ['title','deadline','progress']
    success_url = '/'

class DeleteView(DeleteView):
    template_name = 'delete_confirm.html'
    model = Todo
    success_url = reverse_lazy('/')

index.html的有趣部分：

<!--Table content-->
            {% for todo in object_list %}
            <tr>
              <td class="text-left">{{todo.title}}</td>
              <td> {{todo.deadline}}</td>
              <td>
                <div class="progress">
                  <div class="progress-bar" role="progressbar" aria-valuenow="{{todo.progress}}" aria-valuemin="0" aria-valuemax="100" style="width: {{todo.progress}}%">
                    {{todo.progress}}%
                  </div>
                </div>
              </td>
              <td >
                <div class="btn-group">
                  <a href="edit/{{todo.id}}" role="button" class="btn btn-default">Edit</a>
                  <a href="delete/{{todo.id}}" role="button" class="btn btn-default">Delete</a>
                  <button class="btn btn-default" data-toggle="tooltip" title="Done?" data-placement="right"><span class="glyphicon glyphicon-check"></button>
                </div>
              </td>
          {% endfor %}

如果你的一些人可以帮助一个新手，那会很棒：）

Answer 1

问题在于删除视图中的这一行。

class DeleteView(DeleteView):
    ...
    success_url = reverse_lazy('/')

您可以提供网址：

success_url = '/'

或将reverse_lazy与您要撤消的网址名称一起使用：

success_url = reverse_lazy('index')

删除视图中的NoReverse Match
