Question

我有以下型号：

class Guest(models.Model):
    first_name = models.CharField(max_length=128)
    last_name = models.CharField(max_length=128)
    category = models.ForeignKey(Category)
    player_achievement = models.ForeignKey(PlayerAchievement, related_name="guest_achievements")
    player = models.ForeignKey(Player)

我希望在表单中选择要在我的save_model方法中使用的播放器：

def save_model(self, request, obj, form, change):
        player = ??? how do i get this from the admin form?


        obj.player = player
        obj.save()

Answer 1

这取决于您如何申报表格。如果您继承了ModelForm，那么在大多数情况下，您应该使用ModelChoiceField选择与Player对象关联的Guest，这是通过调用form.cleaned_data.get('player') < / p>
