我正在编写一个Django应用程序，用于跟踪视频游戏中玩家的排名统计数据。
当我定义多对多关系的“through”字段时，我希望使用中间对象的“ordering”Meta字段对结果查询进行排序。
我无法通过下面的测试。我的DB完全迁移了。我哪里误会了？
型号代码

from django.db import models

class Player(models.Model):
    uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, unique=True, editable=False)
    name = models.CharField(max_length=255)

class GameMode(models.Model):
    name = models.CharField(max_length=30)
    leaderboard = models.ManyToManyField(Player, through="ELO", related_name="game_modes")

class ELO(models.Model):
    player = models.ForeignKey(Player, related_name="elos", on_delete=models.PROTECT)
    game_mode = models.ForeignKey(GameMode, related_name="elos", on_delete=models.PROTECT)
    current = models.PositiveIntegerField(default=0)
    peak = models.PositiveIntegerField(default=0)

    class Meta:
        unique_together = ["player", "game_mode"]
        ordering = ("-current",)

测试代码

def test_leaderboard_works_okay_with_different_game_modes(db):
    # checks that creating player elos will have them sorted on the game_mode leaderboard
    game_mode1 = GameMode.objects.create()
    game_mode2 = GameMode.objects.create()
    player1 = Player.objects.create()
    player2 = Player.objects.create()

    ELO.objects.create(game_mode=game_mode1, player=player1, current=1500)
    ELO.objects.create(game_mode=game_mode2, player=player1, current=1000)

    ELO.objects.create(game_mode=game_mode1, player=player2, current=1000)
    ELO.objects.create(game_mode=game_mode2, player=player2, current=1500)

    assert game_mode1.leaderboard.first() == player1
    assert game_mode2.leaderboard.first() == player2
