class Matchscore(TimeStampedModel):
gameevent = models.ForeignKey(GameEvent, null=True, related_name='game_event',on_delete=models.DO_NOTHING)
match_round = models.IntegerField(null=True,blank=True)
team_a = models.ForeignKey(Team,null=True,related_name='team_one',on_delete=models.DO_NOTHING)
team_a_score = models.PositiveIntegerField(null=True,blank=True)
team_b = models.ForeignKey(Team,null=True,related_name='team_two',on_delete=models.DO_NOTHING)
team_b_score = models.PositiveIntegerField(null=True,blank=True)
team_won = models.ForeignKey(Team,null=True,related_name='team', on_delete=models.DO_NOTHING)
