如何在odoo-13中让一个模型的字段值自动出现在另一个模型的字段中？

Question

我需要sub_total_price字段的值将自动在total_price字段。假设sub_total_price = 300，则total_price = 300自动

 *** order.py ***
 class Order_Line(models.Model):
        _name = 'orderline.data'
        _description = "Oder details"
        weight = fields.Float(string="Weight", required=True)
        product_image = fields.Image(string="Image")
        product_quantity = fields.Integer(string="Quantity", required=True)
        making_cost = fields.Integer(string="Making cost", )
        gold_rate = fields.Float(string="Gold Rate", required=True, )
        sub_total_price = fields.Float( compute='gold_cost_count', store=True)
        create_orderline = fields.Many2one('order.order', string="Oder Line")
    
    
    class PaymentLine(models.Model):
        _name = 'paymentline.data'
        # _inherit = 'orderline.data'
        _description = "Payment Details"
    
        price_id = fields.Many2one('orderline.data', )
        total_price = fields.Integer(related='price_id.sub_total_price',string="Total Price")
        advance_payment = fields.Integer(string="Advance payment")
        total_due = fields.Float(string="Total Due")
        create_paymentline = fields.Many2one('order.order', string="Payment Line") 

Answer 1

将total_price行更改为

total_price = fields.Float(string="Total Price", related="price_id.sub_total_price", store=True)

store=True将该值保存到数据库，否则将实时获取该值。
