我的运动是足球和它通常的领域,现在我正在使足球得分,以更新球队的获胜领域。如你所见,我之前已经为足球模型做了updateview,现在我正在对它进行修改,以添加我的新要求,增加win field,以前updateview工作正常,添加“win”field后,我的win field在增加fine,但update field不工作。谢谢。

火柴 Football 对象)未更新,因为您的视图未保存表单给出的匹配项的更新版本。通常, UpdateView 会帮你的 post 方法-通过重写该方法,保存更改是您的责任。

def post(self, request, pk):
    match = self.object = self.get_object() # Get the object that this view is working on and set 'self.object' as the ModelForm is going to look up that attribute
    form = self.get_form() # Get the actual ModelForm
    if not form.is_valid():
        # The user may have put in bad data, you wouldn't want to proceed then
        return super().form_invalid(form)
    form.save() # this updates the instance given to the ModelForm via 'self.object' with the data from the form
    team1 = match.team1
    team2 = match.team2
    score_team1 = match.score_team1
    score_team2 = match.score_team2
    if score_team1 > score_team2:
        football_score = FootballScore.objects.filter(team=team1)[0]
        football_score.win = football_score.win + 1
        football_score.save()
        return HttpResponse('Score Successfully Updated! Team1 won!')
    else:
        football_score = FootballScore.objects.filter(team=team2)[0]
        football_score.win = football_score.win + 1
        football_score.save()
        return HttpResponse('Score Successfully Updated! Team2 won!')
