How to execute function immediately after adding new record?

Question

I have a model and I want to automatically fill one field of this model.
E.g. I have some test model and I want to automaticly genrate EAN13 for this after adding new product:
class product_test(osv.osv):
_name = "product.test"
_description = "Product test"
_table = "product_test"
_columns = {
'name': fields.char('name', size=64, required=True, translate=True, select=True),
'ean13': fields.char('EAN13', size=64, readonly=True),
}
_order = "name"

Hi,

must be overwrite method create

def create(self, cr, user, vals, context=None):
new_id = super(product_test, self).create(cr, user, vals, context)
//your treatment
return new_id

or use  _defaults {}

_columns = { 'ean13' : fields.char('ean13', size=64, ), }
_defaults = {  'ean13': _get_ean13, }
def _get_ref(self, cr, uid,context, *args):
ean13 = // your treatment
return ean13

Thanks.
