引数 '（）'およびキーワード引数 '{' pk '：2}'を指定して '詳細'を反転します。 1つのパターン（s）は試してみました：[ '音楽/（？P <album_id> [0-9] +）/ $']

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

私のアルバムのモデルは次のとおりです。

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}) 

私の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'] 

のURL：

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'), 
    ] 

このコードがDで正常に動作しない理由：はget_absolute_urlで\ VIRTUALENV \サイト\音楽\のmodels.py：

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

私はそれがエラーの上に与えたフォームを使用して、アルバムを追加しようとしました。この問題を解決するにはどうすればよいですか？

編集：私はPKでalbum_id変更

、それは次のよう与えるエラー：

あなたget_absolute_url方法はkwargpk呼ば渡すが、あなたのURLパターンは、引数がalbum_idと呼ばれる期待しています。
