我想改变城市的实际情况资源合作伙伴地址到多个字段而不添加新字段

Question

我的代码看起来像：

# -*- 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')

因此，在我用xml添加视图之后，我的请求是需要更改实际字段而不添加新字段 旧：城市=字段.char新的应该是这样的：city=fields.ManyOne公司你知道吗

Answer 1

只需重写旧API中定义的city字段：

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，许多视图将不再有效，例如合作伙伴看板视图。你知道吗
