How Django URLs are configured

An example of the blog application in the above essay.

The default generated format for urls.py is as follows:

1 """whsweb URL Configuration2 3 The ' urlpatterns ' list routes URLs to views. for more information. See:4 https://docs.djangoproject.com/en/1.8/topics/http/urls/5 Examples:6 Function views7 1. Add an import:from my_app import views8 2. Add a URL to Urlpatterns:url (R ' ^$ ', views.home, name= ' home ')9 class-based viewsTen 1. Add an import:from other_app.views import Home One 2. Add a URL to Urlpatterns:url (R ' ^$ ', Home.as_view (), name= ' Home ') A 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)) the """ -  fromDjango.conf.urlsImportinclude, url -  fromDjango.contribImportAdmin -  +Urlpatterns = [ -URL (r'^admin/', include (Admin.site.urls)), +]

The first way: Apply. View. Methods

URL (r ' ^blog/index/$ ', ' blog.views.archive ')

This means that the access URL matches the R ' ^blog/index/$ ' regular expression, the Web page renders the archive method in the Views view of the blog application

Second Use method: Call Object

Head Import object:

From Blog.views Import Archive

URL (r ' ^blog/index/$ ', archive)

Third Way: Build patterns Assignment

Head Remember Import

From Django.conf.urls import include, url,patterns
Assigning a value to a Urlpatterns object using the Patterns method

Urlpatterns =patterns ('blog.views'  url (r'^blog/index/$  ','archive')               )

Fourth way: include other URLs

The URL (r ' ^blog/', include (' Blog.urls ')) directly contains the URLs configuration under the blog.

Url method:

defURL (regex, view, Kwargs=none, Name=none, prefix="'):    ifisinstance (view, (list, tuple)):#For include (...) processing.Urlconf_module, app_name, Namespace =ViewreturnRegexurlresolver (Regex, Urlconf_module, Kwargs, App_name=app_name, namespace=namespace)Else:        ifisinstance (View, six.string_types): Warnings.warn ('Support for string view arguments to URL () is deprecated and'                ''ll is removed in Django 2.0 (got%s). Pass the callable'                'instead.'%view, removedindjango20warning, Stacklevel=2            )            if  notView:RaiseImproperlyconfigured ('Empty URL Pattern view name not permitted (for pattern%r)'%regex)ifPrefix:view= prefix +'.'+ViewreturnRegexurlpattern (Regex, view, Kwargs, name)

You can see that the URL parameter can be configured in three ways: 1, List 2, tuple 3, string

The Include method returns a tuple
