python - 如何在 Django 中正确设置 URLConf(正则表达式？)

Question

我最近完成了 Django Tutorial现在正在开发我自己的网络应用程序。我遇到的问题是为此应用程序设置 URLConf。我仍然不完全理解 RegEx 匹配以便将不同的页面相互链接(或者我只是忘记了一些简单的事情？？)

我尝试以某种方式设置 URLConf，以便当我单击每个页面上的按钮时，它会转到下一页(总共 5 个)。

它应该是这样的

第 0 页( http://127.0.0.1:8000/ )

第 1 页( http://127.0.0.1:8000/page1/ )

并继续这种模式(http://127.0.0.1:8000/page2/，http://127.0.0.1:8000/page3/，http://127.0.0.1:8000/page4/)

当我在第 0 页上单击 Next Page 时，它将转到第 1 页。当我在第 1 页上单击 Submit 时，URL slug page1 更改为 page2 但仍显示相同的 html 页面。

这是我的两个 urls.py 文件:

"""qfdjango URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.8/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Add an import:  from blog import urls as blog_urls
    2. Add a URL to urlpatterns:  url(r'^blog/', include(blog_urls))
"""
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

# builds URLS for all across the site
# decoupled from mainsite.urls
urlpatterns = patterns('',
    url(r'^',                include('mainsite.urls')),
    url(r'^someOtherPage/',  include('mainsite.urls')),
    url(r'^anotherPage/',    include('mainsite.urls')),
    url(r'^page1/',          include('mainsite.urls')),
    url(r'^page2/',          include('mainsite.urls')),
    url(r'^page3/',          include('mainsite.urls')),
    url(r'^page4/',          include('mainsite.urls')),
    url(r'^admin/',          include(admin.site.urls)),
)

Answer 1

您似乎以错误的方式定义了 url。

应该是这样的:

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^',                include('mainsite.urls')), # include your app urls once
    url(r'^admin/',          include(admin.site.urls)),
)  

然后在应用程序的 urls.py 文件中，url 应该这样定义:

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

urlpatterns = patterns('mainsite.views',
    url(r'^$', 'index'),
    url(r'^someOtherPage/$', 'someOtherPage'),
    url(r'^anotherPage/$', 'anotherPage'),
    url(r'page1/$', 'page_1'), # page 1 url
    url(r'page2/$', 'page_2'), # page 2 url
    url(r'page3/$', 'page_3'), # page 3 url
    url(r'page4/$', 'page_4'), # page 4 url
)
