Django 无法更新模型

Question

我有以下函数来覆盖模型匹配中的默认保存函数

def save(self, *args, **kwargs):
   if self.Match_Status == "F":
        Team.objects.filter(pk=self.Team_one.id).update(Played=F('Played')+1)
        Team.objects.filter(pk=self.Team_two.id).update(Played=F('Played')+1)
        if self.Winner !="":   
          Team.objects.filter(pk=self.Winner.id).update(Win=F('Win')+1, Points=F('Points')+3)
        else:
            return
   if self.Match_Status == "D":
        Team.objects.filter(pk=self.Team_one.id).update(Played=F('Played')+1, Draw = F('Draw')+1, Points=F('Points')+1)
      Team.objects.filter(pk=self.Team_two.id).update(Played=F('Played')+1, Draw = F('Draw')+1, Points=F('Points')+1)
   super(Match, self).save(*args, **kwargs)

我能够很好地保存匹配模型，但团队模型似乎根本没有更新，也没有抛出任何错误。我在这里错过了什么吗？

Answer 1

将其添加到您的 admin.py 中

def save_model(self, request ,obj ,form,change):
   if obj.Match_Status == "F":
    Team.objects.filter(pk=obj.Team_one.id).update(Played=F('Played')+1)
    Team.objects.filter(pk=obj.Team_two.id).update(Played=F('Played')+1)
    if obj.Winner !="":   
      Team.objects.filter(pk=obj.Winner.id).update(Win=F('Win')+1, Points=F('Points')+3)
    else:
        return
     if obj.Match_Status == "D":
    Team.objects.filter(pk=obj.Team_one.id).update(Played=F('Played')+1, Draw = F('Draw')+1, Points=F('Points')+1)
      Team.objects.filter(pk=obj.Team_two.id).update(Played=F('Played')+1, Draw = F('Draw')+1, Points=F('Points')+1)
     obj.save()

你的方法显然没有什么问题。因此，通常的调试技巧适用：您确定该方法确实被调用了吗？您确定 Match 对象的 Match_Status 为 F 或 D 吗？添加一些打印语句以确保确定。
