如何在 Django 中正确设置 URLConf（RegEx？）答案

【问题标题】：How Do I Properly Set Up URLConf in Django (RegEx?)如何在 Django 中正确设置 URLConf（RegEx？）

【问题描述】：

我最近完成了Django Tutorial，现在正在开发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（或者我可能只是忘记了一些简单的事情？？）

我正在尝试设置 URLConf，这样当我在每个页面上单击一个按钮时，它将转到下一页（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/)

并以这种模式继续（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 页单击 Next Page 时，它转到第 1 页。当我在第 1 页单击 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：

【问题讨论】：

url(r'^page1/$', 'page_1')等

标签： python regex django urlconf

【解决方案1】：

您似乎以错误的方式定义了网址。

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 应该定义为：

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
)
