django - django admin admin.TabularInline有多个ForeignKey

Question

我正在尝试在admin部分中实现带有子表单的表单。

form = Fighter()
subform = FighterFightHistory() //All of his fights

我的问题如下:

<class 'fighters.admin.Fights'>: (admin.E202) 'fighters.FighterFightHistory' has more than one ForeignKey to 'fighters.Fighter'.

因此，如何使表单显示每个外键( fighter， opponent)的下拉列表。

2个外键是(请参见下文):

战斗机的链接(fighter)

指向对手的链接(opponent)

fighters / models.py

class FighterFightHistory(TimeStampedModel):
    event = models.ForeignKey('events.Event', null=True)
    fight = models.ForeignKey('fights.Fight', null=True)
    fighter = models.ForeignKey(Fighter, related_name='%(app_label)s_%(class)s_fighter', null=True)
    howitended = models.ForeignKey('fights.HowItEnded', null=True)
    opponent = models.ForeignKey(Fighter, related_name='%(app_label)s_%(class)s_opponent', null=True)

    ended_in_round = models.IntegerField(blank=True, null=True)
    youtube_code = models.CharField(max_length=50, null=True, blank=True)
    win = models.NullBooleanField(blank=True, null=True)

fighters / admin.py

class Fights(admin.TabularInline):
    model = FighterFightHistory
    extra = 30


class FighterAdmin(admin.ModelAdmin):

    list_display = ('name', 'history_completed', 'modified', 'active')
    search_fields = ['name']
    inlines = [Fights, ]

Answer 1

这解决了我的问题(使用 fk_name ):

class Fights(admin.TabularInline):
    model = FighterFightHistory
    extra = 30
    fk_name = 'fighter'
