For exemple, I try to extend account.analytic.line depending on /analytic_multicurrency/account_analytic_line.py . This for the following fields : _columns = { 'aa_currency_id': fields.function(_get_account_currency, method=True, type='many2one', relation='res.currency', string='Account currency', store={ 'account.analytic.account': (_get_account_line, ['currency_id','company_id'], 50), 'account.analytic.line': (lambda self,cr,uid,ids,c={}: ids, ['amount','unit_amount','product_uom_id'],10), }, help="The related analytic account currency."), 'aa_amount_currency': fields.function(_amount_currency, method=True, digits=(16, int(config['price_accuracy'])), string='Amount currency', store={ 'account.analytic.account': (_get_account_line, ['currency_id','company_id'], 50), 'account.analytic.line': (lambda self,cr,uid,ids,c={}: ids, ['amount','unit_amount','product_uom_id'],10), }, help="The amount expressed in the related analytic account currency."), 'company_id': fields.related('general_account_id', 'company_id', type='many2one', relation='res.company', string='Company', store=True, readonly=True), } Now, here are the problems : 1) To extend the triggers on multi, by adding one new object to check, I have to rewrite the whole store dict 2) I will have to redefine _get_account_line or any trigger method as it seems out of scope for store triggering. 3) I can't use 'super' in rewritten method. -> no override is possible No inheritance is possible because the 'self' which is given by the trigger is an instance of the triggering object calling a method of the triggered object. I also tried to define the function that way : from analytic_multicurrency import account_analytic_line _get_account_line = account_analytic_line.account_analytic_line._get_account_line Still the error on store load is TypeError: unbound method _get_account_line() must be called with account_analytic_line instance as first argument (got account.analytic.account instance instead) The only way I found is to rewrite the whole getter method in my new class. That's a bit dirty.
