如何在Django中使用url-创新互联
这篇文章将为大家详细讲解有关如何在Django中使用url，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。
最简单的形式
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'),
)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/$', 'news.views.special_case_2003'),
url(r'^articles/(?P\d{4})/$', 'news.views.year_archive'),
url(r'^articles/(?P\d{4})/(?P\d{2})/$', 'news.views.month_archive'),
url(r'^articles/(?P\d{4})/(?P\d{2})/(?P\d{2})/$', '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/$', 'blog.views.page'),
url(r'^blog/page(?P\d+)/$', '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\d{4})/(?P[a-z]{3})/$','month_display'),
)
urlpatterns += patterns('weblog.views',
url(r'^tag/(?P\w+)/$', '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\d+)/$', 'credit.views.report'),
url(r'^charge/$', 'credit.views.charge'),
)
urlpatterns = patterns('',
url(r'^$', 'apps.main.views.homepage'),
url(r'^help/', include('apps.help.urls')),
url(r'^credit/', include(extra_patterns)),
) 为view函数传递额外参数
from django.conf.urls import patterns, url
urlpatterns = patterns('blog.views',
url(r'^blog/(?P\d{4})/$', '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),
