Question

我是Django Environment的新手（当前版本：1.11.4），我试图找到一个HTML页面来查看问题，但获得例外：

   NoReverseMatch at /music/
Reverse for 'detail' with arguments '('',)' not found. 1 pattern(s) tried: [u'music/(?P<pk>[0-9]+)/$']

我正在考虑的一些文件是：

的index.html

{% extends 'music/base.html' %}
{% block body %}
{% if all_albums %}
<ul>
{% for album in all_albums %}
<li>
    <a href="{% url 'music:detail' album.id  %}">{{album.album_title}}</a> </li>
{% endfor %}
</ul>
{% else %}
<h3>No Album Found </h3>
{% endif %}

{% endblock %}

urls.py

from django.conf.urls import url
from . import views

app_name = 'music'

urlpatterns = [

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

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

views.py

from django.views import generic
from .models import Album
from django.views.generic.edit import CreateView , UpdateView , DeleteView
from django.core.urlresolvers import reverse_lazy



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'

和我的 base.html 文件只有一个导航栏，其中包含一些功能。我只是尽一切努力让它发挥作用，但直到我无法做到这一点，你能帮助我吗？

修改

models.py

from __future__ import unicode_literals

from django.db import models
from django.core.urlresolvers import reverse

# Create your models here.

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


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

    def __str__(self):
        return self.album_title + ' : ' + self.artist

class Song(models.Model):
    album = models.ForeignKey(Album , on_delete = models.CASCADE)
    file_type = models.CharField(max_length = 10)
    song_title = models.CharField(max_length = 250)
    is_favourite = models.BooleanField(default = False)

    def __str__(self):
        return self.song_title

Django：找不到带有参数'（''，）'的'detail'。尝试了1种模式：[u'music /（？P <pk> [0-9] +）/ $']
