Question

我为我的专辑＆＃39;创建了DeleteView。模型，但它现在按预期工作。这是我的脚本：

urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^albums/create/$', views.AlbumCreateView.as_view(), name='album_create'),
    url(r'^albums/(?P<slug>[-\w]+)/update/$', views.AlbumUpdateView.as_view(), name='album_update'),
    url(r'^albums/(?P<slug>[-\w]+)/delete/$', views.AlbumDeleteView.as_view(), name='album_delete'),
    url(r'^albums/(?P<slug>[-\w]+)/$', views.AlbumDetailView.as_view(), name='album_detail'),
    url(r'^albums/$', views.AlbumListView.as_view(), name='album_index'),
    url(r'^songs/create/$', views.SongCreateView.as_view(), name='song_create'),
    url(r'songs/$', views.SongListView.as_view(), name='song_index'),
    url(r'^(?P<song_id>[0-9]+)/favorite/$', views.make_song_favorite, name='song_favorite'),
    url(r'^$', views.AllAlbumListView.as_view(), name='index'),
]

views.py

from django.views.generic import ListView, DeleteView
from django.contrib.auth.mixins import LoginRequiredMixin

from .models import Album

class AlbumListView(LoginRequiredMixin, ListView):
    template_name = 'music/album_index.html'
    context_object_name = 'all_albums'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['album_active'] = True
        return context

    def get_queryset(self):
        queryset = Album.objects.filter(owner=self.request.user).order_by('-release_date')
        return queryset

class AlbumDeleteView(DeleteView):
    model = Album
    template_name = 'music/album_index.html'
    success_url = '/albums/'

album_index.html

{% extends "base.html" %}

{% block content %}
<div class="row">

              </div>
            </div>
          </div>
        </div>
      </div>
      {% endfor %}
    </div>
  </div>
  <div class="col-md-3">
  </div>
</div>
{% endblock %}

正如您在views.AlbumListView中看到的那样，我按照发布日期订购了相册。我的问题是，当我点击删除按钮时，DeleteView删除第一张专辑（即具有最新发行日期的专辑），而不是点击的专辑。我无法弄清问题在哪里。你能帮忙吗？

提前致谢！

Answer 1

id应该是唯一的，但每张专辑都有id="albumDeleteConfirm"的div。

使ID唯一（例如，通过包含slug或pk），并更新data-target。

在DeleteView中，我不会使用您用于列表视图的相同模板music/album_index.html。有一个示例删除模板in the docs。这个模板只是一个后备 - 如果你的模态有效，那么它将不会被看到。

Answer 2

试试这个我正在做同样的事情，我使用这个。 view.py

class AlbumDeleteView(DeleteView):
    model = Album
    success_url = reverse_lazy('music:index')

在url.py中

url(r'album/(?P<pk>[0-9]+)/delete/$', views.AlbumDeleteView.as_view(), name="album_delete")

Django通用视图DeleteView删除意外对象
