    users = fields.ForeignKeyField('models.Users', related_name='events',on_delete=fields.CASCADE)
    prize = fields.DecimalField(max_digits=10, decimal_places=2, null=True)
    prize2 = fields.DecimalField(max_digits=10, decimal_places=2, null=True)
    prize3 = fields.DecimalField(max_digits=10, decimal_places=2, null=True)

    class Meta:
