openerp学习笔记 domain 增加扩展支持，例如支持 <field name="domain">[('type','=','get_user_ht_type()')]</field>

示例代码1，ir_action_window.read ：

# -*- coding: utf-8 -*-
from openerp.osv import fields,osv

class res_users(osv.osv):
   
_name = 'res.users'
    _inherit = 'res.users'

    _columns =
{
               
'ht_type' :
fields.selection([
               
('makings',u'材料'),
               
('theme',u'主题'),
               
('decorate',u'装修')
               
],u'类型'),
               
}

#获取用户具有审核权限的合同类型   
   
def _get_ht_type(self, cr, uid,
context=None):
        return
self.browse(cr, uid, uid,
context=context).ht_type
       

res_users()

# 为 domain 增加扩展支持，使用 get_user_ht_type() 获取用户具有审核权限的合同类型
class
ir_action_window(osv.osv):
    _inherit =
'ir.actions.act_window'

    def read(self, cr, uid, ids, fields=None, context=None,
load='_classic_read'):
        if context
is None:
           
context = {}
        obj_user =
self.pool.get('res.users')
        select
= ids
        if isinstance(ids, (int,
long)):
           
select = [ids]
        res =
super(ir_action_window, self).read(cr, uid, select, fields=fields,
context=context, load=load)
        for r
in res:
           
mystring =
'get_user_ht_type()'
           
if mystring in (r.get('domain', '[]') or
''):
               
r['domain'] = r['domain'].replace(mystring, str(obj_user._get_ht_type(cr,
uid)))
        if isinstance(ids, (int,
long)):
            if
res:
               
return
res[0]
           
else:
               
return False
        return res

ir_action_window()

视图中调用：

<field name="domain">[('type','=','get_user_ht_type()')]</field>
