python – 未调用CreateView中的Django form_valid()和form_invalid()

的CreateView将数据发布到数据库.不幸的是,我从不调用我想保存并执行自定义逻辑的方法form_valid().我读了另一个堆栈溢出响应,form_invalid()可能会发现问题,但我也无法调用该方法.似乎调用的唯一方法是get(),我将其覆盖并放入一个print语句.我做错了什么？

view.py中的类声明

class TeamCreate(CreateView): # Manipulate and use this Method instead of create_team
    model = Team
    # form_class = create_team_form
    fields = ['team_name', 'sport', 'sport_season']
    success_url = '/'

    def get(self, request, *args, **kwargs):
        self.user = request.user
        print 'happening1'
        return super(TeamCreate, self).get(request, *args, **kwargs)


    def form_valid(self, form):
        print 'happening2'
        # form.instance.save()
        # self.user.teams.add(form.instance)
        form.save()
        return super(form_valid, self).form_valid(form)

    def form_invalid(self, form):
        print "form is invalid"
        return http.HttpResponse("form is invalid.. this is just an HttpResponse object")
