ODOO - 通过查询在表中查找值并在字段中输入结果

Question

我创建了一个模块来简单地为客户添加新的电话号码，并自动（ONCHANGE Functrion）从另一个模型中识别电话号码的电话中心，并通过从数据库中搜索输入正确的电话中心名称。

这是我的 .PY 代码：

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

    from openerp import models, fields, api, http


    class Contacts(models.Model):
        _name = 'isp.contacts'

        name = fields.Many2one('res.partner', string="Owner")
        telnumber = fields.Char(string="Tel Number", onchange='onchange_telnumber')
        telcenter = fields.Char(string="Tel Center", required=True)

        @api.onchange('telnumber')
        def onchange_telnumber(self):
            if self.telnumber:
                for record in self:
                    record.telcenter = (self.env.cr.execute(
                        'SELECT name FROM isp_precode WHERE name LIKE %record%'))


    class Telcenter(models.Model):
        _name = 'isp.telcenter'

        name = fields.Char('Center Name', required=True)
        ostan = fields.Char('Provience', required=True)
        city = fields.Char('City', required=True)
        manager = fields.Char('Manager', required=True)
        tel1 = fields.Char('Tel Number 1', required=True)
        tel2 = fields.Char('Tel Number 2', required=True)
        mdf_manager = fields.Char('MDF Manager', required=True)
        mdf_tel = fields.Char('MDF Tel', required=True)
        net_manager = fields.Char('Net Manager', required=True)
        net_tel = fields.Char('NET TEL NUMBER', required=True)


    class Precode(models.Model):
        _name = 'isp.precode'

        name = fields.Char()
        telcenter = fields.Many2one('isp.telcenter',
                                    ondelete='cascade', string="Tel Center", required=True)


    class Ports(models.Model):
        _name = 'isp.ports'

        name = fields.Char(required=True)
        port = fields.Char(required=True)
        floor = fields.Char(required=True)
        raw = fields.Char(required=True)
        dslam = fields.Char(required=True)
        slot = fields.Char(required=True)
        dslamport = fields.Char(required=True)
        dslamip = fields.Char(required=True)
        mothercompany = fields.Many2one('product.category',
                                        ondelete='cascade', string="Mother Company", required=True)
        telcentername = fields.Many2one('isp.telcenter',
                                        ondelete='cascade', string="Tel Center", required=True)

Answer 1

首先，进入 select %record% 被视为文字，同时它应该被参数化。

其次，根本不要将游标用于原始查询，而是使用 ORM：

    @api.onchange('telnumber')
    def onchange_telnumber(self):
        self.telcenter = self.env['isp.telcenter'].search([('name','like',self.telnumber)]).name
