Exception Value: Reverse for 'detail' with arguments '()' and keyword arguments '{'pk': 2}' not found. 1 pattern(s) tried: ['music/(?P<album_id>[0-9]+)/$']

我的相册模型是：

class Album(models.Model):
    artist = models.CharField(max_length=250)
    album_title = models.CharField(max_length=500)
    genre = models.CharField(max_length=100)
    album_logo = models.CharField(max_length=1000)

    def get_absolute_url(self):
        return reverse('music:detail', kwargs={'pk': self.pk})

my views.py：

class IndexView(generic.ListView):
    template_name = 'music/index.html'
    context_object_name = 'all_albums'

    def get_queryset(self):
        return Album.objects.all()

class DetailView(generic.DetailView):
    model = Album
    template_name = 'music/detail.html'

class AlbumCreate(CreateView):
    model = Album
    fields = ['artist', 'album_title','genre', 'album_logo']

网址：

app_name = 'music'    
urlpatterns = [
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^(?P<album_id>[0-9]+)/$', views.DetailView.as_view(), name='detail'),
    url(r'album/add/$', views.AlbumCreate.as_view(), name='album-add'),
    ]

为什么此代码在get_absolute_url中的D：\ virtualEnv \ website \ music \ models.py中无法正常运行：

        return reverse('music:detail', kwargs={'pk': self.pk}) 

当我尝试使用表单添加相册时，它会出现上述错误。我该如何解决这个问题？

修改

当我用pk更改album_id时，会出现以下错误：

   9 :

您的get_absolute_url方法传递了一个名为kwarg的{​​{1}}，但您的网址格式需要一个名为pk的参数。
