I am running Odoo v13 Community Edition and I would like to add a few fields to the order line tree in Purchase Order but I need a field that is present in Purchase Order (currency_rate) so I want to use that field to calculate the costs and prices of products in the converted currency of the company.
This is the code for the module I made:
class PurchOrderLine(models.Model):
_inherit='purchase.order.line'
x_price_unit = fields.Float(readonly=True, compute="calc_unit_p", string='Unit Price in EGP')
x_sub_tot = fields.Float(readonly=True, compute="calc_sub_t", string='Subtotal in EGP')
x_total = fields.Float(readonly=True, compute="calc_total", string='Total in EGP')
@api.depends('price_unit', 'purchase.order.currency_rate')
def calc_unit_p(self):
for p in self:
p.x_price_unit = price_unit * purchase.order.currency_rate
@api.depends('price_subtotal', 'purchase.order.currency_rate')
def calc_sub_t(self):
for p in self:
p.x_sub_tot = price_subtotal * purchase.order.currency_rate
@api.depends('amount_total', 'purchase.order.currency_rate')
def calc_sub_t(self):
for p in self:
p.x_sub_tot = amount_total * purchase.order.currency_rate
This is the error I get while trying to install the module:
Error:
