hello everyone !
I would like to call the method of another model in the compute attribute of a field. is it possible, if so how to do it ?
here is a example of my code:
##########################################
class account(models.Model):
_name = 'pers_io_money.account'
credit = fields.Float( compute="pers_io_money.event._credit_account" )
++++++++++++++++++++++++++++++++++++
class event(models.Model):
_name = 'pers_io_money.event'
amount = fields.Float( )
account_id = fields.Many2one( 'pers_io_money.account', String="account")
@api.depends('account_id')
def _credit_account(self):
if (self.account_id is not False) :
self.account_id.credit = self.amount
###########################################
when I execute the code above, I get the following error:
Traceback (most recent call last):
File "/home/kaly-7/odoo -dev/odoo-12.0/odoo/api.py", line 1039, in get
value = self._data[key][field][record._ids[0]]
