Hi, William

It is because you are trying to create related field using model name, but a related field required at relational field (Many2one) not model.

So in order to achieve this requirement you can use below ways.

• Make it computed same as "amount_total" field like below

• • total_price = fields.Monetary(string='Price Initial', store=True, readonly=True, compute='_amount_all', tracking=4)

  • Inherit the "_amount_all" method,

  • •     @api.depends('order_line.price_total')
          def _amount_all(self):
              """
              Compute the total amounts of the SO.
              """
              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,
                      'total_price': amount_untaxed + amount_tax,
                  })

• Else instead of overriding existing computed method you can define your method like below,

• • total_price = fields.Monetary(string='Price Initial', store=True, readonly=True, compute='_total_price_method', tracking=4)

  • define the "_total_price_method" method,

  • •     @api.depends('order_line.price_total')
          def _total_price_method(self):
              for order in self:
                  order.update({
                      'total_price': order.amount_total,
                  })

Feel free to ask in case you have any doubt related to the above point.

I am still new to odoo development more like 2 weeks ago. Do you mean Inherit the "_amount_all" method is by creating a new function similar to this? For example:

class sale_commission(models.Model):
    _inherit = 'sale.order'

    total_price = fields.Monetary(string='Price Initial', store=True, readonly=True, compute='_prod_price', tracking=4) @api.depends('order_line.price_total')

    def _prod_price(self):
        """
        Compute the total amounts of the SO.
        """
        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,
                'total_price': amount_untaxed + amount_tax,
            })

Thank you so much.
