Python中Django框架利用url来控制登录的方法

from django.conf.urls.defaults import patterns,url 
#or use login_required 
from django.contrib.admin.views.decorators import staff_member_required 
def login_url(regex, view, *p,**args): 
  """ 
  urlpatterns = patterns('', 
  login_url(r'^$',direct_to_template, {'template': '1.html'}), 
  ) 
  """ 
  return url(regex,staff_member_required(view),*p,**args) 
def login_patterns(*p): 
  """ 
  urlpatterns = login_patterns('', 
  (r'^$',direct_to_template,{'template':'1.html'}), 
  ) 
  """ 
  d=[] 
  d.append(p[0]) 
  for i in xrange(1,len(p)): 
  d.append(login_url(*p[i])) 
  return patterns(*d)
