服务器错误:用户在使用之前没有定义
原标题:Server error: user not defined before used

I m 提出这一看法(在Django),要求有用户名的jax查询数据库。 它将用户物体(除条件外)在界定之前使用的服务器错误归来,但上行的定义是:

因此,我认为这或许是一个范围问题,在<条码>上将<<>>用户 = 无<>/代码>放在“<>>/代码”的开头处,知道在审判中将作改动,但我收到<条码>。 无任何数值。

def signup(request):
    if request.method ==  GET :
        return render_to_response( signup.html , context_instance=RequestContext(request))
    elif request.is_ajax(): 
    #query db for user with username provided via ajax, return if it exists
        try:    
            user = User.objects.get(username=request.POST["username"]) 
        except User.DoesNotExist:
            return HttpResponse("false",context_instance=RequestContext(request))
        else:
            return HttpResponse("true", context_instance=RequestContext(request))

function usernameCheck(){
    $.ajax({
        type: POST ,
        url:"http://omnicloud.me/signup", 
      data:{username: $("#username").value}, 
      success:function(response){
        if(response=="true"){
           $( #passAlert ).innerHTML("Sorry, that username is already taken")
        }
        },
        headers:{"X-CSRFToken", getCookie( csrftoken )}
    });

    return !($( #passAlert ).value == "Sorry, that username is already taken")
}

<代码>用户除外:应当参照用户模型(User而不是用户物体(user)作为的用户除外。
