Python NoReverseMatch用于参数
我是Python Django的新手，我正在与网址模式作斗争，我创建的网站有三个超文本标记语言页面和它们各自的三个视图，我附上了我的代码和项目结构的图像请帮助我找到解决方案:项目结构：- enter image description here
所以我的想法是，当我单击index.html时，页面将重定向到图像id为‘detail.html /id’的音乐，现在我想重定向到图像上的其他html页面，在detail.html中单击带有'song_title‘属性的picturedetail.html
代码：-
- 模型.py：-
从django.db导入模型类相册(models.Model)：art_type=models.CharField(max_length=255) album_title=models.CharField(max_length=255) art_method=models.CharField(max_length=255) album_logo=models.FileField() def __str__(self)：return self.album_title；类图片(models.Model)：album=models.ForeignKey(相册，on_delete=models.CASCADE) file_type=models.FileField()
对于album.picture_set.all中的图片，{%扩展'music/base.html‘%} {% block TITY%}专辑详细信息{% ENDBLOCK%} {% block BODY%}{ %} {{picture.song_title}} {% endfor%}
{% endblock %}
- urls.py:-
从django.conf.urls导入url。导入视图
app_name=‘音乐’；urlpatterns =[ url(r'^$'，views.IndexView.as_view()，name=‘索引’)，#/ PictureDetail /id/ url(r'^(?P0-9+)$'，views.DetailView.as_view()，name='detail')，#for picturedetail view url(r'^(?P0-9+)/(?PA-Za-z+)'，views.PicturedetailView.as_view()，name='picturedetail')，]
4.view.py:-
from django.views import generic
from .models import Album
from .models import Picture
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 PicturedetailView(generic.DetailView):
model =Picture
template_name = 'music/picturedetail.html'我得到的错误是：-

url(r'^(?P<pk>[0-9]+)/(?P<song_title>[A-Za-z]+)', views.PicturedetailView.as_view(), name='picturedetail'),这里有两个参数，pk和song_title。尝试以下操作：
{% url 'music:picturedetail' pk=picture.pk song_title=picture.song_title %}https://stackoverflow.com/questions/51202613
