疑问

我怎么想重定向到相同的URL从哪个请求发送，我尝试使用request.path，但它将我重定向到/ accounts/login/url，这是不希望的。

你需要做的是什么跟踪引荐是当你显示的登录表单，可能在存储的用户会话的值，然后将用户重定向回该网址后，他们已经成功登录。

东西：

def login_user(request): 
    if request.POST: 
     sform = LoginForm(request.POST) 
     rform = UserForm() 
     if sform.is_valid(): 
      username = request.POST.get('username') 
      password = request.POST.get('password') 
      user = authenticate(username = username,password = password) 
      if user is not None: 
       if user.is_active: 
        login(request,user) 
        return redirect(request.path) 
       else: 
        state = "Your account is not active." 
        #or first set the user to is active and then log in 
        return redirect(req.session['after_login_url'],user = user) 
       return render_to_response('home.html',{'state':state,'user':user},context_instance = RequestContext(request)) 
      else: 
       state = "Incorrect Username or Password" 
       #sform = LoginForm() 
       form = LoginForm() 
       return render_to_response('register.html',{'state':state,'sform':sform,'rform':rform,'form':form},context_instance = RequestContext(request)) 
     else: 
      state = "Invalid form" 
      dLoginForm = LoginForm() 
      rform = PartialSignupForm() 
      return render_to_response('register.html',{'sform':sform,'rform':rform,'form':form},context_instance = RequestContext(request)) 
    else: 
     dLoginForm = LoginForm() 
     rform = PartialSignupForm() 
     req.session['after_login_url'] = req.META.get('HTTP_REFERER') 
     return render_to_response('category.html',{'dLoginForm':dLoginForm,'rform':rform},context_instance = RequestContext(request)) 

当然，你也应该补充检查，以确保该HTTP_REFERER头存在，并确保after_login_url键存在（并可能有一个健全的价值，如果外部网站直接链接到您的登录页面或类似链接），并且如果有任何这些测试失败，请安全回退l（就像用户的个人资料页面或您的网站索引页面一样）。
