Question

我有一个供员工签到/签出的时钟应用程序，该应用程序可以正常工作，但是当您位于用户活动页面上时，请在签入或签出表格后将其寄回给您到user-activity.html页，但是表中没有数据加载，也没有从视图中加载数据。刷新页面后，数据仍然存在，但我不确定为什么会这样。我将附加2张图片，其中一张在按下“签入/签出”按钮之前，另一张在

之后

这是我的看法。感谢您提供的帮助

class ActivityView(LoginRequiredMixin, View):

    def get(self, request, *args, **kwargs):
        context = {}
        toggle = UserActivity.objects.current(request.user)
        user_data = UserActivity.objects.filter(user=request.user).order_by('-timestamp')
        current_users = UserActivity.objects.order_by('user', '-timestamp').distinct('user')

        context['toggle'] = toggle
        context['user_data'] = user_data
        context['current_users'] = current_users
        return render(request, "administration/timesheets/user-activity.html", context)

    def post(self, request, *args, **kwargs):
        context = {}
        toggle = UserActivity.objects.toggle(request.user)
        context['toggle'] = toggle
        return render(request, "administration/timesheets/user-activity.html", context)

在您的帖子功能中，我认为您输入有误：

toggle = UserActivity.objects.toggle(request.user)

我认为，您需要：

toggle = UserActivity.objects.current(request.user)

返回渲染发送到正确的位置，但没有数据，直到页面重新加载？
