Django urls配置方式

例子以上一篇随笔中的blog应用进行.

urls.py默认生成的格式如下：

 

"""whsweb 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 include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
]

第一种方式：应用.视图.方法

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

这个就表示访问url匹配r'^blog/index/$'正则表达式的情况下，网页呈现blog应用下views视图中的archive方法

第二用方式：调用对象

头部导入对象：

from blog.views import archive

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

第三种方式：构建patterns赋值

头部记得导入

from django.conf.urls import include, url,patterns
使用patterns方法赋值给urlpatterns对象

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

第四种方式：包含其他url

url(r'^blog/', include('blog.urls')),直接包含blog下的urls配置。

url方法：

def url(regex, view, kwargs=None, name=None, prefix=''):
    if isinstance(view, (list, tuple)):
        # For include(...) processing.
        urlconf_module, app_name, namespace = view
        return RegexURLResolver(regex, urlconf_module, kwargs, app_name=app_name, namespace=namespace)
    else:
        if isinstance(view, six.string_types):
            warnings.warn(
                'Support for string view arguments to url() is deprecated and '
                'will be removed in Django 2.0 (got %s). Pass the callable '
                'instead.' % view,
                RemovedInDjango20Warning, stacklevel=2
            )
            if not view:
                raise ImproperlyConfigured('Empty URL pattern view name not permitted (for pattern %r)' % regex)
            if prefix:
                view = prefix + '.' + view
        return RegexURLPattern(regex, view, kwargs, name)

可以看到url参数可以采用三种方式配置：1、list 2、tuple 3、string

include方法返回的是tuple
