S URL網址在Django中不起作用

我試圖在Django項目中設置Slug網址。我不斷收到404錯誤，無法找到我錯過的東西。我之前做過幾次，但由於某種原因，我必須缺少一些東西。S URL網址在Django中不起作用

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'), 
]

你只是在你看來無條件這就提出了一個404，我建議你至少'除例外爲e： '然後記錄異常詳情。目前，你的觀點或模型中的任何錯誤都會拋出404錯誤。也可以看看實際發生的情況。 – vastlysuperiorman

在視圖中收到'slug'的值是多少？ – alecxe

和視圖名稱必須小寫！ – doniyor

謝謝你們的幫助。我發現這個問題與@vastlysuperiorma一些幫助

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
