Question

我是Django的新手，我使用基于类的视图向我的餐厅列表添加删除选项，但是当我点击删除按钮时，我得到一个空白屏幕并在控制台中收到以下错误 “不允许的方法（POST）：”

以下是我的代码

views.py

from __future__ import unicode_literals
from django.db.models import Q
from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import render, get_object_or_404
from django.views import View
from django.contrib.auth.mixins import LoginRequiredMixin
from django.views.generic import TemplateView, ListView, DetailView, 
CreateView,DeleteView
from django.urls import reverse_lazy

class RestaurantDeleteView(DeleteView):
model = RestaurantLocation
success_url = reverse_lazy('restaurants:list')

urls.py

from django.conf.urls import url, include

from .views import (

     RestaurantListView,
     RestaurantDetailView,
     RestaurantCreateView,
     RestaurantDeleteView,
   )

urlpatterns = [
    url(r'^create/$', RestaurantCreateView.as_view(), name= 'create'),
    url(r'^$',RestaurantListView.as_view(), name= 'list'),
    url(r'^(?P<slug>[\w-]+)/$',RestaurantDetailView.as_view(),        
          name="detail"),
    url(r'^(?P<slug>[\w-]+)/delete/$', RestaurantDeleteView.as_view(), 
     name="restaurant-delete"),
   ]

delete.html

<form method="post" action="" >{% csrf_token %}
<p>Are you sure you want to delete <strong> {{ obj }}</strong>?</p>
<input type="submit" value="DELETE" />
</form>

Answer 1

你的delete.html中的

方法目前是＆＃34; t＆＃34;，更改为＆＃34; post＆＃34;看看是否有效。

Answer 2

您的表单操作指向/的根网址。此路线由RestaurantListViews确定，并通过GET方法加入。在您的示例中，您尝试使用POST访问此内容，因此您收到错误。

要使用RestaurantDeleteView更改表单中的action属性，请指向现有的餐馆，例如：

<form method="post" action="{your_existing_restaurant_slug}/delete" >
    {% csrf_token %}
    ...
...

使用DeleteView不允许使用方法（POST）
