formfield_for_foreignkey 和内联管理

我只想展示特定比赛中与球队相关的球员。通常，当我这样做时，它会向我显示数据库中的所有球员。这是我的 models.py

class InningsCard(models.Model):
    fixture = models.ForeignKey(Fixture)
    team = models.ForeignKey(Team)
    runs = models.IntegerField(max_length=6, default=0)
    wickets = models.IntegerField(max_length=6, default=0)
    overs = models.FloatField(max_length=6, default=0.0)

    def __unicode__(self):
        return str(self.team)

class BattingDetail(models.Model):
    STATUS_CHOICES = (
        ('no', 'not out'),
        ('bowled', 'bowled'),
        ('caught', 'caught'),
        ('lbw', 'lbw'),
    )
    innings = models.ForeignKey(InningsCard)
    player = models.ForeignKey(Player)
    runs = models.IntegerField(max_length=5, default=0)
    status = models.CharField(max_length=15, choices=STATUS_CHOICES, default='no')

    def __unicode__(self):
        return str(self.player)

现在这是我的 admin.py 包含 formfield_for_foreignkey，但它不起作用。

class BattingInline(admin.TabularInline):
    model = BattingDetail
    extra = 0

    def formfield_for_foreignkey(self, db_field, request=None, **kwargs):

        if db_field.name == 'player':
            kwargs = Player.objects.filter(team = request.team)
        else:
            pass

        return super(BattingInline, self).formfield_for_foreignkey(db_field, request, **kwargs)


class InningCardAdmin(admin.ModelAdmin):
    inlines = [BattingInline]

我哪里可能出错了？

//mouse

1. 你要替换整个kwargs与查询集。kwargs必须是字典，并且您要查找的特定键是“queryset”：

   kwargs['queryset'] = Player.objects.filter(team=request.team)
   

2. 我几乎肯定请求实际上不会有属性team。除非您自己将其添加到此处未显示的某些代码中，否则您需要找到另一种方法来获取当前的“团队”。您可以从中解析出团队IDrequest.path例如，并将其用于查找。

作为旁注，else如果您只是打算，则无需使用该条款pass there.
