Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
I declared a computed field:
'member_still_pay': fields.float(compute='_get_total', type='float', string='Still to pay')
@api.multi
def _get_total(self):
temp = 0.0
for rec in self:
temp = sum(line.payment_amount for line in rec.member_payments)
rec.member_still_pay = rec.member_cotisation - temp
The problem is I don't have the good value in member_still_pay. The field payment_amount is a one2many. Somebody know what is false?
