Question

我是Python Django的新手，我正在努力应对URL模式，我正在创建的网站包含三个HTML页面和它们各自的三个视图，我正在查看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

所以想法是，当我单击index.html时，页面将重定向到具有图像ID（例如“ music / id”）的detail.html，现在我想重定向至图像上的其他html页面，请在detail.html中单击到picturedetail.html。具有“ song_title”属性

代码：-

Models.py：-

from django.db import models



class Album(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;


class Picture(models.Model):
  album=models.ForeignKey(Album,on_delete=models.CASCADE)
  file_type=models.FileField()
  song_title=models.CharField(max_length=245)

detail.html：-

  {% extends 'music/base.html'  %}
  {% block title %}Album Details{% endblock %}
  {% block body %}
  <ul>
     {% for picture in album.picture_set.all %}
      <div class="col-sm-4 col-lg-2">
           <div class="thumbnail">
              <a href="{% url 'music:picturedetail' picture.song_title %}">
               <img src="{{ picture.file_type.url }}" class="img-responsive">
                        </a>
                        <div class="caption">
                          <h6>{{picture.song_title}}</h6>
                        </div>
                </div>

        </div>

     {% endfor %}
  </ul>

{％endblock％}

urls.py：-

从django.conf.urls

导入URL 来自。导入视图

app_name='music';
urlpatterns = [

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

    # /music/id/
    url(r'^(?P<pk>[0-9]+)$',views.DetailView.as_view(),name='detail'),
    #for PictureDetail view
    url(r'^(?P<pk>[0-9]+)/(?P<song_title>[A-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'

我遇到的错误是：-

Answer 1

url(r'^(?P<pk>[0-9]+)/(?P<song_title>[A-Za-z]+)', views.PicturedetailView.as_view(), name='picturedetail'),

这有两个参数pk和song_title。请尝试以下操作：

{% url 'music:picturedetail' pk=picture.pk song_title=picture.song_title %}

适用于参数的Python NoReverseMatch
