foreign-keys - open erp中如何实现外键

Question

我是打开 erp 的新手，我有两个表 master 和 details，我想在 detail 表中使用 master 的 id 作为外键。我怎样才能做到这一点？有谁请帮忙！！

我的代码是

from osv import osv,fields
class wlan_master(osv.osv):
    _name = 'wlan_master'
    _columns = {
        'AP_name'       :fields.char(),
        'description'   :fields.char(),
        'ip_address'    :fields.char(),
    }
class wlan_details(osv.osv):
    _name = 'wlan_details'
    _columns = {
        'wireless_workmode'     :fields.char(),
        'enable_wireless'       :fields.char(),
        'ssid'                  :fields.char(),
        'channel'               :fields.char(),
        'wireless_mode'         :fields.char(),
        'channel_bandwidth'     :fields.char(),
        'rate'                  :fields.char(),
        'broadcast_ssid'        :fields.char(),
        'client_isolation'      :fields.char(),
        'wmm_announcement'      :fields.char(),
        'fragement_threshold'   :fields.char(),
        'rts'                   :fields.char(),
        'dtim_gap'              :fields.char(),
        'beacon_gap'            :fields.char(),
        'preamble_type'         :fields.char(),
        'encryption_mode'       :fields.char(),
        'filter_mode'           :fields.char(),
    }

使用 one2many 和 many2one 链接表。我在您的表中添加了 detail_ids 和 master_id。请检查一下。

from osv import osv,fields
class wlan_master(osv.osv):
    _name = 'wlan_master'
    _columns = {
        'AP_name'       :fields.char(),
        'description'   :fields.char(),
        'ip_address'    :fields.char(),
        'detail_ids': fields.one2many('wlan_details','master_id','Details')
    }


class wlan_details(osv.osv):
    _name = 'wlan_details'
    _columns = {
        'master_id': fields.many2one('wlan_master','Master'),
        'wireless_workmode'     :fields.char(),
        'enable_wireless'       :fields.char(),
        'ssid'                  :fields.char(),
        'channel'               :fields.char(),
        'wireless_mode'         :fields.char(),
        'channel_bandwidth'     :fields.char(),
        'rate'                  :fields.char(),
        'broadcast_ssid'        :fields.char(),
        'client_isolation'      :fields.char(),
        'wmm_announcement'      :fields.char(),
        'fragement_threshold'   :fields.char(),
        'rts'                   :fields.char(),
        'dtim_gap'              :fields.char(),
        'beacon_gap'            :fields.char(),
        'preamble_type'         :fields.char(),
        'encryption_mode'       :fields.char(),
        'filter_mode'           :fields.char(),
    }
