如何在Bootstrap表中添加Bootstrap按钮

使用Ubuntu 16.04 LTS部署我的python应用程序。配置完所有内容后，该应用将手动运行。我想使用主管自动执行，已经安装了主管并对其进行了配置。但是如果我运行：

主管配置文件：

; supervisor config file

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)
chmod=0700                       ; sockef file mode (default 0700)

[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor            ; ('AUTO' child log dir, default $TEMP)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock …

我正在使用python django框架开发一个简单的应用程序,我使用基于类的视图,当我使用UpdateView并尝试运行我的模板时,我得到此错误;

'QuerySet' object has no attribute '_meta'

这是我的观看代码

class UpdateStaff(LoginRequiredMixin, UpdateView):
    template_name = 'app/update_staff.html'
    form_class = UpdateStaffForm
    model = Staff

    def get_object(self, queryset=None):
        obj = Staff.objects.filter(pk=self.kwargs['staff_id'])
        return obj

    def post(self, request, *args, **kwargs):
        form = self.form_class(request.POST or None, 
                               instance=self.get_object())
        if form.is_valid():
            obj = form.save(commit=False)
            obj.save()
            messages.success(self.request, "Staff has been updated")
            return self.get_success_url()
        else:
            messages.error(self.request, "Staff not updated")
            return HttpResponseRedirect(reverse('update_staff'))

    def get_success_url(self):
        return HttpResponseRedirect(reverse('manage_staffs'))

    def get_context_data(self, **kwargs):
        context = super(UpdateStaff,         
                        self).get_context_data()
        context['messages'] = messages.get_messages(self.request)
        context['form'] = self.form_class(self.request.POST or None, 
                                          instance=self.get_object()) …
