现在我想让每位法官在运动员身上得分：

models.py:

class Athlete(models.Model):
  name = models.CharField()

class Judge(models.Model):
  name = models.Charfield()

我的admin.py到目前为止：

class Score(models.Model):
  athlete = models.ForeignKey(Athlete)
  judge = models.ForeignKey(Judge)
  score = models.SmallIntegerField()

Scores应该可以在Django-Admin-Backend中编辑。这是我的问题。如何在我的数据库中获得每个'判断'的ScoreInlines？我不喜欢使用ChoiceFields，也不需要从Inlines添加更多评委。

换句话说：我如何获得独特的“Inlines”？有没有办法在查询集上限制它？

您可以使用unique_together选项确保每位裁判最多对运动员进行一次评分：

class Score(models.Model):
    athlete = models.ForeignKey(Athlete)
    judge = models.ForeignKey(Judge)
    score = models.SmallIntegerField()

    class Meta:
        unique_together = (
            ('athlete', 'judge'),
        )

然而，这无助于用户界面部分问题，即为Django管理员中的每个裁判创建内联。

根据DB中的元素限制内联（Django＆gt; 1.7）
