Here is The problems

class Purchase(models.Model):

_name = 'purchase'

name = fields.Char(string="name")

orderNumber = fields.Char(string="Order Number")

subpurchase_ids = fields.One2many('subpurchase', 'purchase_id', string="Purchase Lines")

customer_id = fields.Many2one('customer', string='partner', required=True)

state = fields.Selection([

('new', 'New'),

('draft', 'Draft'),

('validate', 'Validated'),

('cancel', 'Cancelled')],

string='Status', required=False, readonly=True, copy=False, default='new')

@api.onchange('tax', 'unTax')

@api.multi

def _compute_amount_total(self):

self.amount_total = self.unTax + self.tax

@api.depends('subpurchase_ids', 'subpurchase_ids.amount') #tambah kalo butuh relasi tambahan

@api.multi

def _total_price(self):

for purchase in self :

total_price = 0

for subpurchase in purchase.subpurchase_ids:

total_price += subpurchase.amount

purchase.unTax = total_price

class SubPurchase(models.Model):

_name = 'subpurchase'

Thanks to you all for answer this question

I think you need to use a for loop in `_compute_amount_total` and `_compute_amount` methods.

Just give it a try and if this does not solve the issue, please post the traceback.

Hi,

The Single ton error can be sorted out by iterating the self over a for loop or by using self.ensure_one() . In your code, at a first glance everything seems to be fine, you have iterated the self and the one2many lines. So will suggest you to cross check the code by putting the print statements in the code and see.

Suppose if any of the variables is getting the value as sale.order(38, 39), just a sample, then make sure that the value is then iterated over the loop such a way that we will get sale.order(38) and sale.order(39).

If you have the added the fields amount and amount_total in the Tree views, make sure that the corresponding compute function is also iterated over the for loop.

@api.onchange('tax', 'unTax')       
@api.multi
def _compute_amount_total(self):
    for rec in self:
        rec.amount_total = rec.unTax + rec.tax

Thanks
