Django删除时不会重定向到确认页面
你好,
我在一个表上做了一个标准的CRUD，它在另一个表上是外键。我使用Django视图类。创建，读取和更新工作，但我有一个错误的删除。当我删除一个项目时，我被重定向到具有良好删除地址(' localhost/table_name/pk/delete ')的详细页面(Read页面)。
我遵循Django项目和几个教程中描述的标准方法。
下面是我的代码:
model.py:
class Badge(models.Model):
id_badge = models.AutoField(primary_key=True)
title = models.CharField(max_length=100)
category = models.CharField(max_length=60)
level = models.IntegerField()
image_badge = models.ImageField(upload_to='badge_image/', null=True, blank=True, default='ex-par-nat_logo.png')
class Meta:
managed = True
db_table = 'badge'
view.py:
from django.shortcuts import redirect, render
from UsersApp.tribut_sign_up_form import TributSignUpForm
from UsersApp.tutor_sign_up_form import TutorSignUpForm
from UsersApp.child_sign_up_form import ChildSignUpForm
from django.contrib.auth import authenticate, login
from django.contrib.auth import logout as account_logout
from UsersApp.models import Tribut, Tutor, Child, Account
from django.http import HttpResponse
from django.contrib.auth.decorators import login_required
from UsersApp.decorator import tribut_required
@method_decorator([login_required, author_required], name='dispatch')
class BadgeListView(ListView):
model = Badge
ordering = ('title', )
template_name = 'ArticlesApp/badge_list.html'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
return context
def get_queryset(self):
queryset = Badge.objects.all()
return queryset
@method_decorator([login_required, author_required], name='dispatch')
class BadgeCreateView(CreateView):
model = Badge
# form_class = ArticleCreationForm
fields = ('title', 'category', 'level', 'image_badge')
template_name = 'ArticlesApp/badge_create.html'
def get_context_data(self, **kwargs):
return super().get_context_data(**kwargs)
def form_valid(self, form):
form.save()
return redirect('badge_list')
@method_decorator([login_required], name='dispatch')
class BadgeReadView(DetailView):
model = Badge
template_name = 'ArticlesApp/badge_read.html'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
return context
@method_decorator([login_required, author_required], name='dispatch')
class BadgeUpdateView(UpdateView):
model = Badge
fields = ['title', 'category', 'level', 'image_badge']
template_name = 'ArticlesApp/badge_update.html'
def get_success_url(self):
view_name = 'badge_list'
return reverse_lazy(view_name)
@method_decorator([login_required, author_required], name='dispatch')
class BadgeDeleteView(DeleteView):
model = Badge
success_url = reverse_lazy('badge_list')
url.py:
from django.conf import settings
from django.conf.urls.static import static
from django.urls import path, include
from ArticlesApp import views as article_views
urlpatterns = [
path('badge/', article_views.BadgeListView.as_view(), name='badge_list'),
path('badge/add/', article_views.BadgeCreateView.as_view(), name='badge_create'),
path('badge/<int:pk>/<slug:slug>/', article_views.BadgeReadView.as_view(), name='badge_read'),
path('badge/<int:pk>/', article_views.BadgeUpdateView.as_view(), name='badge_update'),
path('badge/<int:pk>/delete/',
article_views.BadgeDeleteView.as_view(
template_name='ArticlesApp/badge_confirm_delete.html'),
name='badge_confirm_delete'),
]
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
badge_confirm_delete.html:
{% extends "base_user.html" %}
{% block content %}
<form method="post">{% csrf_token %}
<p>Are you sure you want to delete "{{ object }}"?</p>
<input type="submit" value="Confirm">
</form>
{% endblock %}
Django按照url模式定义的顺序遍历它们，并返回第一个与传入路径匹配的模式。
路径"badge/1/delete/"匹配"badge_read"Url，因为它是第一个匹配("delete">
移动"badge_confirm_delete"badge_read"前面的UrlUrl以便与第一个
匹配urlpatterns = [
path('badge/', article_views.BadgeListView.as_view(), name='badge_list'),
path('badge/add/', article_views.BadgeCreateView.as_view(), name='badge_create'),
path('badge/<int:pk>/delete/',
article_views.BadgeDeleteView.as_view(
template_name='ArticlesApp/badge_confirm_delete.html'),
name='badge_confirm_delete'),
path('badge/<int:pk>/<slug:slug>/', article_views.BadgeReadView.as_view(), name='badge_read'),
path('badge/<int:pk>/', article_views.BadgeUpdateView.as_view(), name='badge_update'),
]
这意味着"delete"不能用作段塞，如果这是一个问题，你可以重新安排你的路径部分，使动作出现在前面，如"badge/delete/int:pk/">
