javascript - 确定新站点用户的最佳方法 - Django

Question

我想要一种方法来检查是否有人使用 django 填写了他们的个人资料信息(新用户)。如果他们还没有，我想展示一个在填写所有信息之前不会消失的模态。无论他们转到哪个页面，它都应该显示此模式，直到填写完毕。

我是否应该使用 javascript(ajax) 检查路由以进行检查并返回带有答案的 json 请求？如果 json 对象说它们是新的，我会动态地将模态附加到屏幕。

更新:我使用 django 的身份验证系统。这是一个登录示例。检查将是类似的，但我将使用我在另一个扩展 Django 的基本用户类的应用程序中制作的模型。我称之为 user_profile。我可能会检查是否设置了用户的名字。如果不是，我想执行检查。

    def auth_login(request):
    if request.POST:

        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(username=username, password=password)

        if user:
        # the password verified for the user
            if user.is_active:
                print("User is valid, active and authenticated")
                request.session['id'] = user.id
                request.session['email'] = user.email
                login(request, user)
                data = {}
                data['status'] = "login"
                return HttpResponse(json.dumps(data), content_type="application/json")
                #redirect
            else:
                print("The password is valid, but the account has been disabled!")
        else:
            # the authentication system was unable to verify the username and password
            print("The username and password were incorrect.")
            data = {}
            data['status'] = "The username and password are incorrect"
            return HttpResponse(json.dumps(data), content_type="application/json")

    return HttpResponse("hello")

一种选择是将模型方法放在您的user_profile 的模型上:

class UserProfile(models.Model):
    name = CharField...
    ...other fields...

    def get_is_new(self):
        if self.name is None:  # You could include other checks as well
            return True
        return False

然后你可以像这样检查你的 View :

def auth_login(request):
    if request.POST:

        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(username=username, password=password)

        if user:
        # the password verified for the user
            if user.is_active:
                print("User is valid, active and authenticated")
                if user.get_is_new() is True:
                    # Return the modal
                request.session['id'] = user.id
                .......rest of your code..........
