Django循环模型参考

这是解决此问题的另一种方法。我没有创建循环依赖关系，而是创建了一个额外的表来存储球员和球队之间的关系。所以最终看起来像这样：

class Team(Model):    name = CharField(max_length=50)    def get_captain(self):        return PlayerRole.objects.get(team=self).playerclass Player(Model):    first_name = CharField(max_length=50)    last_name = CharField(max_length=50, blank=True)    def get_team(self):        return PlayerRole.objects.get(player=self).teamPLAYER_ROLES = (    ("Regular", "Regular"),    ("Captain", "Captain")    )class PlayerRole(Model):    player = oneToOneField(Player, primary_key=True)    team = ForeignKey(Team, null=True)    role = CharField(max_length=20, choices=PLAYER_ROLES, default=PLAYER_ROLES[0][0])    class meta:        unique_together = ("player", "team")

在存储方面，它的效率可能比建议的解决方法略低，但是它避免了循环依赖，并保持了数据库结构的整洁。欢迎发表评论。
