python - 我想将 res.partner 地址中的实际城市字段更改为 Many2one 字段，而不添加新字段

Question

我的代码如下:

# -*- encoding: utf-8 -*-

from openerp import models,fields, api

class ResPartner(models.Model):
    _name = 'res.partner'
    _inherit = 'res.partner'

    city_id = fields.Many2one('res.city','Ville',stored = True 
                               ,ondelete='restrict')

class ResCity(models.Model):
    _name = "res.city"
    _description = "Ville"

    name = fields.Char(u"Nom",required = True)
    state_id = fields.Many2one("res.country.state", 'Zone',ondelete='restrict')

所以在我在 xml 中添加 View 后，但我的请求是我需要更改实际字段而不添加新字段旧的:city = fields.char 新的应该看起来像:city = fields.many2one

Answer 1

只需覆盖旧 API 中定义的 city 字段即可:

from openerp import models,fields, api
from openerp.osv import fields as ofields

class ResPartner(models.Model):
    _inherit = 'res.partner'

    _columns = {
        'city': ofields.many2one('res.city', 'Ville', ondelete='restrict'),
    }

请记住，很多 View 将不再起作用，例如合作伙伴看板 View 。
