<code> from django.conf.urls import patterns, url urlpatterns = patterns('', url(r'^articles/2003/$', 'news.views.special_case_2003'), url(r'^articles/(\d{4})/$', 'news.views.year_archive'), url(r'^articles/(\d{4})/(\d{2})/$', 'news.views.month_archive'), url(r'^articles/(\d{4})/(\d{2})/(\d+)/$', 'news.views.article_detail'), )</code>
其中,正则表达式中组匹配出来的结果可以作为positional parameters传递给view.
如果url是www.yourdomain/articles/2005/,则会匹配第二条规则,执行news.views.year_archive('2005').
注意点
域名部分会被过滤掉
articles的前面不需要添加/,因为前序url的末尾一定会有/
任何组匹配的变量,都会议字符串的形式传递给view, 虽然通过(\d{4})匹配出了2005,但2005任然会被当做字符串传递给year_archive
利用named group来传递参数
可以通过以下形式为特定的组指定一个名称.
urlpatterns = patterns('', url(r'^articles/2003/$', 'news.views.special_case_2003'), url(r'^articles/(?P<year>\d{4})/$', 'news.views.year_archive'), url(r'^articles/(?P<year>\d{4})/(?P<month>\d{2})/$', 'news.views.month_archive'), url(r'^articles/(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d{2})/$', 'news.views.article_detail'), )
这样的话,组的匹配结果会通过keyword parameters的形式传递给view.例如year_archive(year='2005')
利用named group可以为view指定一个默认参数来匹配多条规则。
# URLconf from django.conf.urls import patterns, url urlpatterns = patterns('', url(r'^blog/$', 'blog.views.page'), url(r'^blog/page(?P<num>\d+)/$', 'blog.views.page'), ) # View (in blog/views.py) def page(request, num="1"): # Output the appropriate page of blog entries, according to num.
指定view前缀(提取公因式)
patterns函数的第一个参数即是view的前缀
from django.conf.urls import patterns, url urlpatterns = patterns('news.views', url(r'^articles/(\d{4})/$', 'year_archive'), url(r'^articles/(\d{4})/(\d{2})/$', 'month_archive'), url(r'^articles/(\d{4})/(\d{2})/(\d+)/$', 'article_detail'), )
指定多个view前缀
urlpatterns = patterns('myapp.views', url(r'^$', 'app_index'), url(r'^(?P<year>\d{4})/(?P<month>[a-z]{3})/$','month_display'), ) urlpatterns += patterns('weblog.views', url(r'^tag/(?P<tag>\w+)/$', 'tag'), )
include其它匹配模块
from django.conf.urls import include, patterns, url urlpatterns = patterns('', # ... snip ... url(r'^comments/', include('django.contrib.comments.urls')), url(r'^community/', include('django_website.aggregator.urls')), url(r'^contact/', include('django_website.contact.urls')), # ... snip ... )
当然也可以直接include其它patterns
from django.conf.urls import include, patterns, url extra_patterns = patterns('', url(r'^reports/(?P<id>\d+)/$', 'credit.views.report'), url(r'^charge/$', 'credit.views.charge'), ) urlpatterns = patterns('', url(r'^$', 'apps.main.views.homepage'), url(r'^help/', include('apps.help.urls')), url(r'^credit/', include(extra_patterns)), )
为view函数传递额外参数
from django.conf.urls import patterns, url urlpatterns = patterns('blog.views', url(r'^blog/(?P<year>\d{4})/$', 'year_archive', {'foo': 'bar'}), )
直接使用view函数
from django.conf.urls import patterns, url from mysite.views import archive, about, contact urlpatterns = patterns('', url(r'^archive/$', archive), url(r'^about/$', about), url(r'^contact/$', contact), )
