At first I thought this would be easy, since it's not a big deal. I'll go straight to the problem.
def verify_service(self, cr, uid, ids, context=None):
record = self.browse(cr, uid, ids)[0]
rec_value = record.nr_service
cr.execute("SELECT nr_service FROM services WHERE nr_service = %s", (rec_value,))
values = cr.fetchall()
if not values: # It means the database has NO value
return True # continues to save the Form
else:
return False # If there's any value with the value of the field "rec_value" it returns error!
_columns = {
'nr_service':fields.integer('Nr. Service', size = 30, required = True),
_constraints = [
(verify_service, 'Error: Already that ID in the database!', ['nr_service']),
Isn't this so simple? But no matter what value I put inside the 'nr_service' field, it displays always the constraint message. What am I doing wrong?
