# -*- coding: utf-8 -*-

from openerp import models, fields


class fleet_vehicle_direction(models.Model):

    _name = 'fleet.vehicle.direction'
    name = fields.Char(related='vehicle_id.name', string='vehicle name', store=True)
    vehicle_id = fields.Many2one('fleet.vehicle', 'select vehicle name', required=True, help='select vehicle name')
    Quotations_id = fields.One2many('sale.order', 'name', 'Quotation', required=True,help='select  Quotation name')

Answer 1

您在创建 Quotations_id 模型字段时遇到问题，反向名称非常错误。您不能将 name 指定为反向字段，因为它已经在销售订单中并且反向字段应该是 Many2one 所以要编辑您的字段定义必须像那样

Quotations_id = fields.One2many('sale.order', 'fleet_id', 'Quotation', required=True,help='select  Quotation name')

并且您必须在 sale.order 模型中添加 fleet_id 字段作为 Many2one 关系，如下所示

class SaleOrder(models.Model):
     _inherit= 'sale.order
     fleet_id = fields.Many2one('fleet.vehicle.direction')
