Hello,

OK I really must post a disclaimer before asking because this is a really basic question but as I am learning python and OpenERP I can't seem to figure it out and its taking me forever.

I am trying to understand some custom code I requested from a developer. Basically what I need is to add some values to a variable called vals, but I look and I look and I can't find where is vals initially created or where it is getting its contents from.

Here is the code of the class I am working with:

class guest_amenities_vals(osv.osv):
    _name = "sim.guest_amenities_vals"
    _description = "GuestAmenitiesVals"
    _columns = {

        'name': fields.char('Name',required=True),
        'cols': fields.many2one('sim.resumen_wizard','Order Reference', required=True, ondelete='cascade', select=True),
        'price': fields.float('Price'),
        'period': fields.float('Period')
    }
    _defaults = {
        'price' : 0,
    }

    def create(self, cr, uid, vals, context=None):
        print vals
        print "------------"
        if 'cols' in vals and 'name' in vals:
            existing_recs = self.search(cr, uid, ['&',('cols','=',vals['cols']),('name','=',vals['name'])], context=context)
        if not existing_recs:
            return super(guest_amenities_vals, self).create(cr, uid, vals, context=context)
        else:
            ids = existing_recs[0]
            if ids:
                super(guest_amenities_vals, self).write(cr, uid,[ids], vals, context=context)
                print vals
                return ids

guest_amenities_vals()

From what I could debug the code gets executed when the user clicks on a 'Print' button from a wizard.

Vals has something like this {'price': 3000, 'name': 'b', 'cols': 116L}

What I am trying to do is also add the Period to vals so I can insert it into de DB

So the question is how would you look for were vals is initialized so I can pass the value of period to this class and insert it into the DB like the rest of the fields?

Please again excuse me if this is super basic. I spent a lot of time digging into the code and can't find it so any clue on where to look or what to look for will be deeply appreciated.
