自定义计算返回“NoneType”对象不可调用django

我正在为我的系统做一些计算,我需要得到一个 superuser 像这样

location = LocationData.objects.filter(email=self.request.user.email).count() ,

然后我需要计算该用户的所有许可证,就像这样

count = MyUser.objects.filter(location_count=self.request.user.email).count() ,

我需要检查一下 location == count 以及 * 有价格的地点,

if count == location:
       context['social'] = location * FRISTPRICE

当我得到价格,我需要显示在模板上。

完整的视图是

class AdminDashboard(TemplateView):
    """
    """
    template_name = 'administration/admin.html'

    @cached_property
    def get_context_data(self, **kwargs):
        context = super(AdminDashboard, self).get_context_data(**kwargs)
        user = MyUser.objects.get(pk=self.request.user.pk)

    # check if user is superuser if not don't include him
        if user.is_superuser:
            # check how much locations does user have
            location = LocationData.objects.filter(email=self.request.user.email).count()

            # check how much user have licences payed for
            count = MyUser.objects.filter(location_count=self.request.user.email).count()

            # if count is == to location then the location is proper
            # so count * package = application sales
            if count == location:
                context['first_package'] = location * FIRSTPRICE

            if count == location:
                context['second_package'] = location * SECONDPRICE

            if count == location:
                context['third_package'] = location * THIRDPRICE

            return context

完全错误是 HERE ,我的第一个猜测是上下文不能返回,并且这个计算不好,所以可以有人帮助我理解为什么我会得到这个错误,谢谢。
