Question

我正在django 1.9中使用基于类的视图，并且试图找出如何在不使用表单的情况下更新对象（单击按钮后）。我不需要任何用户输入即可更新对象。你能帮我吗？

在models.py

中

class State(models.Model):
stateID = models.SmallIntegerField(primary_key=True)
isOpen = models.BooleanField(default=True, help_text='Designates whether the registration is open.', verbose_name='active')

def __unicode__(self):
    return bool(self.isOpen)

在views.py

class OpenTournament(View):
    model = State

    def get(self, request, *args, **kwargs):
        queryset = State.objects.all()

        if queryset.count() != 1:
            State(stateID=1, isOpen=True).save()
            return HttpResponseRedirect('/success_url/')

        else:
            #need to update the table from a button click
            return HttpResponseRedirect("/updated/")

是的。我找到了。通过主键访问状态

ws.query("C:/ProgramData/Microsoft/Windows/Start Menu/Windows Update.lnk", console.log);

/* From console:
null { expanded:
   { args: 'startmenu',
     workingDir: 'C:\\Windows\\system32',
     icon: 'C:\\Windows\\system32\\wucltux.dll' },
  target: '%windir%\\system32\\wuapp.exe',
  args: 'startmenu',
  workingDir: '%windir%\\system32',
  runStyle: 1,
  icon: '%windir%\\system32\\wucltux.dll',
  iconIndex: '0',
  hotkey: 0,
  desc: 'Delivers software updates and drivers, and provides automatic updating options.' }
*/
