如何在计算字段中使用track_visibility = always和store = true？

Question

在这里，我需要在crm机会方面的实际销售。

我已完成所有计算部分，但不存储该值 track_visibility='always'和store=True。

from odoo import api,fields,models,_

class CrmLead(models.Model):

    _inherit = "crm.lead"


    actual_sales = fields.Float(string="Actual Sales", store=True, compute="compute_actual_sales", track_visibility='always')

    @api.depends('order_ids')
    def compute_actual_sales(self):
        for record in self:
            total_actual_sales_amount_in_opp = 0
            for order in record.order_ids:
                if order.state == 'sale':
                    sales_amount_in_opp = order.amount_total
                    print">>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<sales_amount_in_opp>>>>>>>>>>>>>>><", sales_amount_in_opp  
                    total_actual_sales_amount_in_opp = order.amount_total + total_actual_sales_amount_in_opp
            print">>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<total_sales_amount_in_opp>>>>>>>>>>>>>>><", total_actual_sales_amount_in_opp  
        record.actual_sales = total_actual_sales_amount_in_opp
