我在这里看不到任何名为favorite的url，这也是错误告诉您的：

app_name = 'music'

urlpatterns = [


    url(r'^$',views.IndexView.as_view(), name='index'),

    url(r'^(?P<pk>[0-9]+)/$',views.DetailView.as_view(), name='details'),

]

你可能复制粘贴了详细信息.html或者你忘了在应用程序“音乐”中指定“最爱”的网址

编辑：正如您澄清的，您无法在您的onw上解决问题：改变详细信息.html因此：

^{pr2}$

替换为

<form action="#" method="post">

你的网站至少应该加载。在

编辑2：

看完你在评论中链接的youtube视频后：所有答案都在视频和评论中！你没有更新详细信息.html. 仔细观察min1:50。顺便说一句，我的替换表单操作的解决方案也会起作用，但是输出将与您可能期望的稍有不同。。。我希望这能让你开始；）
