Hey guys, I was hoping someone could check over my implementation.

I have defined this model (and only included the relevant parts)

class EstateProperty(models.Model): 

  expected_price = fields.Float(required=True)

  _sql_constraints = [        ('check_expected_price', 'CHECK(expected_price > 0)',         'The expected price should be positive')    ]

Is this wrong? When I try to save negative numbers onto my form, my system is allowing it.
