如何结合 HttpResponseRedirect & render_to_response？

Question

当用户登录时，他被 HttpResponseRedirect 重定向到“/welcome/”url。但我也想 return 下面注释掉的语句，因为我也想将字典传递给模板。帮我想个办法把这两个语句或任何其他的解决方案结合起来。

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))

您可以为此使用消息框架.. from django.contrib import messages

views.py

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

另一种选择就是为此使用会话。！但在会话中你会找到显示后隐藏消息的方法...

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