Hi,

I'm create a module to try and learn OpenERP. I want a res.partner to have points and for each sale he does he needs to get an extra point.

When you create a res.partner you can give him an initial points value, but it can't be negative. class res_partner(osv.Model): _inherit = 'res.partner'

   _columns = {
        'points': fields.integer(string = 'Collected points'),
    }

    _defaults = {
                 'points': 0,
    }

   def _check_points(self, cr, uid, ids, context=None):
    obj = self.browse(cr, uid, ids[0], context=context)
    if obj.points < 0:
        return False
    return True

_constraints = [
    (_check_points, 'Points must be 0 or above', ['points']),
]

How do I write my test?

def test_negative_points(self):
        cr, uid = self.cr, self.uid
        loyalty_id = self.partner_model.create(cr, uid, dict(
                ...,
                points=-10,
                ))

Because this always gives me an error.
