Odoo 如何为项目销售订单创建字段

我有用于快速访问与项目相关的实体的字段。例如：

class project(models.Model):
    _name = "project.project"
    _description = "Project"
    _inherit = 'project.project'

    production_order_ids = fields.One2many('mrp.production', 'project_id', 'Production orders')
    purchase_order_ids   = fields.One2many('purchase.order', 'project_id', 'Purchase orders')
    ....

我正在尝试在项目中创建一个销售订单ID。我的第一次尝试没有成功：

sale_order_ids   = fields.One2many('sale.order', 'project_id', string='Sale orders')

因为字段sale.order.project\u id的类型为account.analysis.account

project.project对象继承自account.analysis.account。如果它们共享相同的Id，则此查询应该可以正常工作，但它们没有。因此，导航将是：

"project.project".analytic_account_id" -> sale.order".project_id

---

结果将是相应的销售订单。

使用计算字段：

sale_order_ids = fields.One2many('sale.order', compute='_get_sale_orders', string='Sale orders')

@api.model
def _get_sale_orders(self):
    for record in self:
        record.sale_order_ids = self.env['sale.order'].search([('project_id', '=', record.analytic_account_id.id)]).ids
