如何結合HttpResponseRedirect和render_to_response？

Question

當用戶登錄時，他被HttpResponseRedirect重定向到「/ welcome /」url。但是我也想返回下面註釋的語句，因爲我也想將字典傳遞給模板。幫助我一個方法來結合這兩個語句或任何其他解決方案。

Views.py

def home(request): 
     templatename="login.html" 
     if request.method=="POST": 
      u=request.POST.get("username")  
      p=request.POST.get("password") 
      user=authenticate(username=u, password=p) 
      if user is not None: 
       if user.is_active: 
        print "This User is valid, active and authenticated" 
        login(request,user) 
        state = "You're successfully logged in!" 
        return HttpResponseRedirect("/welcome/") 
        #return render_to_response(templatename,{'state':state, 'user':user}, context_instance=RequestContext(request)) 


       else: 
        print "This User is valid but the account has been disabled" 
        state="This User is valid but the account has been disabled" 

      else: 
       print "The Username and Password entered were incorrect" 
       state = "Your username and/or password were incorrect." 
       #return render_to_response(templatename,{'state':state, 'user':user}, context_instance=RequestContext(request)) 

     else: 
      user=None 
      state=None 

     return render_to_response(templatename, {'state':state, 'user':user}, context_instance=RequestContext(request))

您可以使用消息框架的.. from django.contrib import messages

views.py

messages.success(request, "You're successfully logged in!") 
return HttpResponseRedirect("/welcome/") 

另一種選擇就是使用會話了點。 ！但在會話中，你會發現隱藏消息後的方式...

#views.py 
request.session['state'] = "You're successfully logged in!" 
HttpResponseRedirect("/welcome/") 
#html 
{{ request.session.state }}
