信息库

The information repository is a semantics tree in which the datas that are not the ressources are stocked. We find in this structure:

1. 预设的值

2. 有条件的值；

   • 州（省）取决于邮编，

   • 付款方法取决于伙伴，

1. 事件客户端的反应动作；

   • 滑鼠在请款单菜单上单击，

   • 打印一份请款单，

   • 对一个伙伴的动作， …

信息库(IR)有 3 个物件方法；

• 在语义树里增加值

• 在语义树里删除值

• 在一个选定表单里取得所有值

设定数值

The ir_set tag allows you to insert new values in the “Information Repository”. This tag must contain several field tags with name and eval attributes.

这些属性是依据存取信息库的方法定义的；我们必须在提供标签时设置以下属性：keys, args, name, value, isobject, replace, meta, 和其他一些可选的属性。

范例:

<ir_set>
    <field name="keys" eval="[('action','client_print_multi'),('res_model','account.invoice')]"/>
    <field name="args" eval="[]"/>
    <field name="name">Print Invoices</field>
    <field name="value" eval="'ir.actions.report.xml,'+str(l0)"/>
    <field name="isobject" eval="True"/>
    <field name="replace" eval="False"/>
</ir_set>

信息库物件方法

def ir_set(cr, uid, key, key2, name, models, value, replace=True, isobject=False, meta=None)

def ir_get(cr, uid, key, key2, models, meta=False, context={}, res_id_req=False)

def ir_del(cr, uid, id):

...
    res = ir.ir_set(cr, uid, key, key2, name, models, value, replace, isobject, meta)
...
...
    if not report.menu_id:
        ir.ir_set(cr, uid, 'action', 'client_print_multi', name, [(model, False)], action, False, True)
    else:
        ir.ir_set(cr, uid, 'action', 'tree_but_open', 'Menuitem', [('ir.ui.menu', int(m_id))], action, False, True)
...
...
    res = ir.ir_get(cr, uid, [('default', self._name), ('field', False)], [('user_id',str(uid))])
...
    account_payable = ir.ir_get(cr, uid, [('meta','res.partner'), ('name','account.payable')], opt)[0][2]
