Field.function / method not automatically updating field

i have a function which currently works when a user pick and item from  a dropdown menu it changes the value of  another field.

however the other field only changes when i click save how can i make this that as soon as i change the value of  the dropdown field the , other fields value changes without having to click save.

.py file

class account_analytic_account(osv.osv):

_name = "account.analytic.account"

_inherit = "account.analytic.account"

def get_rental(self,cr,uid,ids,context,table1,obj2):


obj1 = self.pool.get('mm.control')

for record in self.browse(cr, uid , ids):

table1 = obj1.search(cr,uid,[('company','=',record.invcompany_id.id)])



print table1

print record.invcompany_id

print obj2.rental_split

return x

_columns = {

'invcompany_id': fields.many2one('res.company', 'Invoicing Company ' , domain="[('company_type', '=', 'Property Company')]" ,required=True, select=1),

'rental_split': fields.function(get_rental , method=True ,string= 'Rent', store=False, type="integer", help="Rent split of total rent amount *25"),




<field name="rental_split"/>

<field name="invcompany_id"/>


Any ideas to make the field automatically update without saving

In OpenERP v7, the function and related fields  are computed and stored only after the SAVE event.

For your question, you need to have an onchange that does the same computation as your function field.

In acounting module, we have a similar case for "writeoff_amount" field.  Here, you can check that with the help of onchange they set the value for this field.
