Slug URL在Django中不起作用

Question

我正在嘗試在Django項目中設置Slug url。 我不斷收到404錯誤，找不到我所缺少的東西。 我之前已經做過幾次，但是由於某種原因我必須錯過一些東西。

models.py

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

# Create your models here.
class Pages(models.Model):
    title = models.CharField(max_length=250, default="Add Title Here")
    content = models.TextField(default="Add Content Here")
    slug = models.SlugField(unique=True)
    seo_title = models.CharField(max_length=250, default="Add Title Here")
    seo_description = models.CharField(max_length=160, default="Add Seo Description")
    active = models.BooleanField(default=False)
    timestamp = models.DateTimeField(auto_now_add=True, auto_now=False, null=True)
    updated = models.DateTimeField(auto_now_add=False, auto_now=True, null=True)

    def __unicode__(self):
        return self.title

    class Meta:
        unique_together = ('slug', 'title')

    def get_absolute_url(self):
        return reverse("single_page", kwargs={"slug": self.slug})

views.py

from django.shortcuts import render, get_object_or_404, Http404

# Create your views here.
from .models import Pages

def Single(request, slug):
    try:
        page = get_object_or_404(Pages, slug=slug)
        context = {'page': page}
        template = 'pages/page_detail.html'
        return render(request, template, context)
    except:
        raise Http404

urls.py

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

urlpatterns = [
    url(r'^(?P<slug>[\w-]+)/$', views.Single, name='single_page'),
]

謝謝大家幫助。 我在@vastlysuperiorma的一些幫助下找到了問題

Views.py

def single(request, slug):
try:
    page = get_object_or_404(Pages, slug=slug)
    context = {'page': page}
    template = 'pages/page_detail.html'
    return render(request, template, context)
except Pages.DoesNotExist:
    raise Http404
