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.[b]read ：[/b]

# -*- 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>

其它示例代码：

<record id="action_company_partners_form" model="ir.actions.act_window">
<field name="name">Company Partners</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">res.partner</field>
<field name="view_type">form</field>
<field name="domain">[('category_id', 'in', get_company_categories())]</field>
</record>

View Code

​[b]示例代码2，self.[b]search ：[/b]
[/b]

This is an example.
Look to USER_PARTNER_IDS and USER_PAYMENT_MODE_IDS.

Part of example.xml:
<record id="action_income_payment_line_tree" model="ir.actions.act_window">
<field name="name">Входящие платежи</field>
<field name="res_model">payment.line</field>
<field name="view_type">form</field>
<field name="view_mode">tree,form</field>
<field name="limit">300</field>
<field name="context">{"search_default_today":1}</field>
<field name="domain">[('partner_id','in','USER_PARTNER_IDS')]</field>
<field name="search_view_id" ref="view_payment_line_search"/>
</record>

<record id="action_outgoing_payment_line_tree" model="ir.actions.act_window">
<field name="name">Исходящие платежи</field>
<field name="res_model">payment.line</field>
<field name="view_type">form</field>
<field name="view_mode">tree,form</field>
<field name="limit">300</field>
<field name="context">{"search_default_today":1}</field>
<field name="domain">[('payment_mode','in','USER_PAYMENT_MODE_IDS')]</field>
<field name="search_view_id" ref="view_payment_line_search"/>
</record>

Part of example.py:
def search(self, cr, uid, args, offset=0, limit=None, order=None, context=None, count=False, xtra=None):
user = self.pool.get('res.users').browse(cr, uid, uid, context=context)
new_args = []
for arg in args:
if type(arg) is not tuple:
new_args += arg
continue
if arg[2] == 'USER_PARTNER_IDS':
new_args += [(arg[0], arg[1], [p.id for p in user.partner_ids])]
elif arg[2] == 'USER_PAYMENT_MODE_IDS':
new_args += [(arg[0], arg[1], [m.id for m in user.payment_mode_ids])]
else:
new_args += [arg]
return super(payment_line, self).search(cr, uid, new_args, offset, limit, order, context, count)
