Python Django-QuerySet到多维列表

我有以下型号：

class Fixture(models.Model):
    id = models.AutoField(primary_key=True)
    home_team = models.ForeignKey(Player, related_name="home")
    away_team = models.ForeignKey(Player, related_name="away")
    game_week = models.PositiveSmallIntegerField(max_length=2, default=0)

我要做的是创建一个多维列表，该列表按“game_week”属性对我的所有装置对象进行分组。例如：

   fixtures[0] = [<FixtureObject 1>, <FixtureObject 2>]
   fixtures[1] = [<FixtureObject 3>, <FixtureObject 4>]
   fixtures[2] = [<FixtureObject 5>]
   fixtures[3] = [<FixtureObject 6>]

fixture[0]=[，]
固定装置[1]=[，]
固定装置[2]=[]
固定装置[3]=[]

其中赛程列表索引为不同的比赛周。做这件事的最简单、最通俗的方法是什么？

最简单的方法是使用字典：

 fixtures = Fixture.objects.all()
 fixture_dict = {}
 for fixture in fixtures:
    fixture_dict.setdefault(fixture.game_week, []).append(fixture)
