Hello,

I am currently creating a module that will display calculations in invoices. The problem is that I do not know how to retrieve values. I read a lot of documentation but I still do not understand how can i do it .

res_config.py

from openerp import models, fields, api

class unite_beneficiaire(models.Model):
    _name='unite.beneficiaire.config.settings'
    _inherit='res.config.settings'

    default_smic=fields.Float(string='Taux horaire du SMIC', default='9.61',default_model='unite.beneficiaire.config.settings')
    default_coeff=fields.Float(string='Coefficient',default='0.85',default_model='unite.beneficiaire.config.settings')
    default_traitementbrutannuel=fields.Float(string='Traitement brut annuel minimum', default='17169.12',default_model='unite.beneficiaire.config.settings')

account_invoice.py

from openerp import models, api, _, fields

class account_invoice(models.Model): 
 _inherit='account.invoice' 

 def _secteur_public(self, cr, uid, ids, context=None):
     _ub = self.pool.get('unite.beneficiaire.config.settings').browse(cr,uid,ids)
     # i want to get the 'default_traitementbrutannuel' and 'ammout_total' value and return :
     # return (ammout_total/default_traitementbrutannuel)
             


 ub=fields.Float(string='Unité bénéficiaire',compute='_secteur_public',readonly=True)

I want to get the 'default_traitementbrutannuel' value of 'unite.beneficiaire.config.settings' class and 'ammout_total' value of the current class and return :

(ammout_total/default_traitementbrutannuel)

thank you
