Django admin site auto populate combo box based on input

Question!

hi i have to following model class Match(models.Model):

    Team_one = models.ForeignKey('Team', related_name='Team_one') 
    Team_two = models.ForeignKey('Team', related_name='Team_two') 
    Stadium = models.CharField(max_length=255, blank=True)
    Start_time = models.DateTimeField(auto_now_add=False, auto_now=False, blank=True, null=True)
    Rafree = models.CharField(max_length=255, blank=True)
    Judge = models.CharField(max_length=255, blank=True)
    Winner = models.ForeignKey('Team', related_name='winner', blank=True)    
    updated = models.DateTimeField('update date', auto_now=True )
    created = models.DateTimeField('creation date', auto_now_add=True )
    def save(self, force_insert=False, force_update=False):
      pass

   @models.permalink
   def get_absolute_url(self):
       return ('view_or_url_name')
class MatchAdmin(admin.ModelAdmin):
   list_display = ('Team_one','Team_two', 'Winner')
   search_fields = ['Team_one','Team_tow']

 admin.site.register(Match, MatchAdmin)

i was wondering is their a way to populated the winner combo box once the team one and team two is selected in admin site ?

Theres no real easy way to do that with the django admin. It's possible, but it would require you to replace the admin form, and subclass the widget with some javascript that copys the Team into the box. Way more effort than it's worth.

If I were you, I'd just have winner_team and loser_team fields
