Dynamic choices on inlines

[Mariano DAngelo]

Hi, I'm new in django and I'm searching how to the following...

I've the following models

class Fighter(Person):

    pass

class Fight_Event(models.Model):

    pass

# INLINE MODEL

class Fight(models.Model):

    event = models.ForeignKey(Fight_Event)

    fighter1 = models.ForeignKey(Fighter,related_name='fighter1')

    fighter2 = models.ForeignKey(Fighter,related_name='fighter2')     

    winner = # choices fighter1 or fighter2

class Fight_Event_Fight_Inline(admin.TabularInline):

    model = Fight

    fk_name = 'event'

class Fight_Event_ADMIN (ForeignKeyAutocompleteAdmin):

    inlines = [Fight_Event_Fight_Inline,]

    

admin.site.register(Fight_Event,Fight_Event_ADMIN)

I need to add the 2 figther selected on the admin the a third widget to select the winner.... 

I need to load with javascript, or there another way?

Thanks
