Django NoReverseMatch 在 /admin/r/7/2/ 错误网址

Question

我在查看博客的单个帖子时遇到问题。我正在尝试实现使用 slugline 和内容 ID 的 url。这是我的错误：

NoReverseMatch 在 /admin/r/7/2/ 使用参数 '()' 和关键字参数 '{'slugline': u'test-post-3', 'id': 2}' 的“文章”反向。尝试了 0 个模式：[]

views.py：

from django.shortcuts import render, get_object_or_404
from django.http import HttpResponse, HttpResponseRedirect
from django.template import RequestContext, loader
from django.core.urlresolvers import reverse
from django.views import generic
from django.utils import timezone

# Create your views here.

from articles.models import Content

class IndexView(generic.ListView):
    template_name = 'articles/index.html'
    context_object_name = 'latest_articles_list'

    def get_queryset(self):
        return Content.objects.filter(
            published_date__lte=timezone.now()
        ).order_by('-published_date')[:5]


def detail(request, slugline, poll_id):
    article = get_object_or_404(pk=poll_id)
    return render(request, 'articles/detail.html', {'article': article})

urls.py:

from django.conf.urls import patterns, url
from articles import views

urlpatterns = patterns('',
    url(r'^$', views.IndexView.as_view(), name = 'index'),
    #url(r'^(?P<slugline>[-\w\d]+), (?P<pk>\d+)/$', views.DetailView.as_view(), name='detail')
    url(r'^(?P<slugline>[-\w\d]+),(?P<id>\d+)/$', view=views.detail, name='article'),
)

models.py：

from django.db import models
from django.db.models import permalink
from django.utils import timezone
import datetime
# Create your models here.


class Content(models.Model):
    title = models.CharField(max_length=100, unique=True)
    slugline = models.SlugField(max_length=100, unique=True)
    body = models.TextField()
    published_date = models.DateTimeField('date published')

    def __unicode__(self):
        return self.title

    @permalink
    def get_absolute_url(self):
        return ('article', (), {
            'slugline': self.slugline,
            'id': self.id,
        })

    def was_published_recently(self):
        now = timezone.now()
        return now - datetime.timedelta(days=1) <= self.published_date <= now
    was_published_recently.admin_order_field = 'published_date'
    was_published_recently.boolean = True
    was_published_recently.short_description = 'Published recently?'

我认为 get_absolute_url 应该是：

@permalink
def get_absolute_url(self):
    from django.core.urlresolvers import reverse
    return reverse('article', args=[self.slugline,str(self.id)])
