python - 注释无法正常显示/工作

Question

我问了这个question关于找到受伤最严重的前 5 名球员的注释，但现在我在显示正确信息时遇到问题，我认为这应该是它自己的问题。

这是我当前的观点:

def home(request):
    context={}
    most_recent = PlayerInjury.objects.all().order_by('-timestamp')[:5]
    news = News.objects.all()
    most_injured = PlayerInjury.objects.annotate(injury_count=Count('id')).order_by('-injury_count')[:5]
    print most_injured
    context['most_injured'] = most_injured
    context['most_recent'] = most_recent
    context['news'] =  news
    return render_to_response('dash/home.html', RequestContext(request, context))

模型.py

class PlayerInjury(models.Model):
    player =  models.ForeignKey(Player)
    injury_type = models.ForeignKey(Injury)
    injury_date = models.DateField(verbose_name='Injured On', null=True, blank=True)
    description = models.CharField(verbose_name='Description', max_length=180, null=True, blank=True)
    status = models.ForeignKey(Status)
    projected_return = models.DateField(verbose_name='Projected Return Date', null=True, blank=True)
    hide = models.BooleanField(default=False)
    returned = models.BooleanField(default=False)
    timestamp = models.DateTimeField(auto_now_add=True)

class Player(models.Model):
    first_name = models.CharField(verbose_name='First Name', max_length=30, null=True, blank=True)
    last_name = models.CharField(verbose_name='Last Name', max_length=30, null=True, blank=True)
    team = models.ForeignKey(Team, related_name='Team played for')
    pob = models.CharField(verbose_name='Place of Birth', max_length=100, null=True, blank=True)
    dob = models.DateField()
    age =  models.IntegerField(null=True, blank=True)
    height = models.CharField(verbose_name='Height', max_length=10, null=True, blank=True)
    weight = models.CharField(verbose_name='Weight', max_length=10, null=True, blank=True)
    drafted_by = models.ForeignKey(Team, related_name='drafted by')

但是，当我打印出 most_injured 时，我得到:
- 玩家A
- 玩家B
- 玩家A

实际上，我认为它应该显示为:
- 玩家A
- 玩家B

由于事实上玩家 A 比玩家 B 受到的伤害更多

有什么建议吗？

我认为这应该是这样的。
- 球员 A(2 次受伤)
- 球员 B(1 次受伤)
- 等等

尝试这样做:

most_injured = Player.objects.annotate(injury_count=Count('playerinjury')).order_by('-injury_count')[:5]
