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>
