我真的很困惑为什么我收到Http404错误。为了更清楚这是我的代码：
我的应用名为书
视图.py
from django.shortcuts import render_to_response
from django.http import Http404
from django.template import RequestContext
from books.models import *
def index(request):
title = 'Book Gallery'
books = Book.objects.all().order_by('-id')
lang_list = Lang.objects.all().order_by('-lang')
template = 'books/index.djhtml'
context = {'books': books, 'title': title, 'lang_list': lang_list}
return render_to_response( template, context, context_instance=RequestContext(request) )
def by_book_slug(request, bookslug):
slug = bookslug
try:
book = Book.objects.get(slug=slug)
except:
raise Http404
title = book.name
template = 'books/singlebook.djhtml'
context = {'book': book, 'title': title}
return render_to_response( template, context, context_instance=RequestContext(request) )
def by_lang_slug(request, langslug):
filter = langslug
try:
language = Lang.objects.get(slug=filter)
except:
raise Http404
lang_list = Lang.objects.all().order_by('-lang')
books = Book.objects.filter(lang=language).order_by('-id')
title = language
template = 'books/by_language.djhtml'
context = {'books': books, 'title': title, 'filter': filter, 'lang_list': lang_list}
return render_to_response( template, context, context_instance=RequestContext(request) )
urls.py inside my book app folder
from django.conf.urls import patterns, include, url
from books import views
urlpatterns = patterns('',
url(r'(?P<langslug>.*)/$', views.by_lang_slug, name='by_lang'),
url(r'(?P<bookslug>.*)/$', views.by_book_slug, name='by_book'),
url(r'^$', views.index, name='book_gallery'),
)
与 langslug url conf 相关的链接有效，但 bookslug url conf 的链接不起作用。当我尝试调低和调高它们时，其中一个可以工作，而另一个不能。
我真的不知道这里发生了什么。任何帮助都会是很大的帮助。谢谢。

Http404当指定的 slug 与数据库中的任何查询都不匹配时，我已经包含了一个 raise方法。我感到困惑的是，当我尝试切换 langslug 和 bookslug urlconf 时，与这些 url 之一相关联的链接有效，而另一个无效。
