У меня возникла такая ситуация, когда мне нужно получить начальную цену из класса B, потому что вычисления наследуются в «sale.order», который я не могу поместить в модель A. Как это сделать, поскольку каждый раз, когда я перемещаю вычисления для класса model_A возникнет ошибка, так как он не сможет найти наследование, но если я добавлю на него наследование, снова возникнет ошибка.
class model_A(models.Model):
_name='module.model_a'
sale_id = fields.Many2one(string='sale', comodel_name='sale.order')
initial_price_value =???
class model_B(models.Model):
_inherit = 'sale.order'
model_id = fields.One2many(string='model_b', comodel_name='module.model_a', inverse_name='sale_id')
initial_price = fields.Monetary(string="Price Initial", store=True, readonly=True, compute='_product_amount',
tracking=4)
amount_untaxed = fields.Monetary(string="Untaxed Amount", store=True, readonly=True, compute='_product_amount',
tracking=5)
amount_tax = fields.Monetary(string="Taxes", store=True, readonly=True, compute='_product_amount')
@api.depends('order_line.price_total')
def _product_amount(self):
for order in self:
amount_untaxed = amount_tax = 0.0
for line in order.order_line:
amount_untaxed += line.price_subtotal
amount_tax += line.price_tax
order.update({
'amount_untaxed': amount_untaxed,
'amount_tax': amount_tax,
'amount_total': amount_untaxed + amount_tax,
'initial_price': amount_untaxed + amount_tax,
})
Я пытался это:
initial_price_value = fields.Monetary(related='sale_id.initial_price')
и получил эту ошибку
И еще не работает. Initial_price_value не получил значения total_price. На картинке ниже показана общая стоимость sale.order.line.
Но начальная цена в моем древовидном представлении все еще равна нулю. он должен отражать сумму 141k
