無法繼承OpenERP中的HR.Employee

Question

請告訴我我的錯誤在哪裏。我需要添加一個名爲kanganyname（經理姓名）的新字段。但它給了我一個錯誤。我跟着開發指南，做此修改：

這裏是我的view.xml用

<record model="ir.ui.view" id="namelist_dailyupdate"> 
    <field name="name">checkroll.daily.update.form</field> 
    <field name="model">checkroll.daily.update</field> 
    <field name="inherit_id" ref="hr.view_employee_form" /> 
    <field name="type">form</field> 
    <field name="arch" type="xml"> 
     <form string="daily_update"> 
      <field name="kanganyname" /> 
     </form> 
    </field> 
</record> 

<record model="ir.actions.act_window" id="action_inherit_ex"> 
    <field name="name">checkroll.daily.update.form</field> 
    <field name="model">checkroll.daily.update</field> 
    <field name="view_type">form</field> 
    <field name="view_mode">form</field> 
</record> 

這裏是我的模型類。

class dailyupdate(osv.osv): 
    _name = "checkroll.daily.update" 
    _inherit = "hr.employee" 
    _description = "This table is for daily update" 
    _columns = { 
     'kanganyname': fields.char('Kangany Name', size=256, required=True) 
    } 

dailyupdate() 

這是我的錯誤：

XML代碼是完全錯誤的繼承。

<record model="ir.ui.view" id="namelist_dailyupdate"> 
    <field name="name">checkroll.daily.update.form</field> 
    <field name="model">checkroll.daily.update</field> 
    <field name="inherit_id" ref="hr.view_employee_form" /> 
    <field name="type">form</field> 
    <field name="arch" type="xml"> 
     <form string="daily_update"> 
      <field name="kanganyname" /> 
     </form> 
    </field> 
</record> 

在此代碼中要添加新的領域你不指定，你可以這樣定義

<record model="ir.ui.view" id="namelist_dailyupdate"> 
    <field name="name">checkroll.daily.update.form</field> 
    <field name="model">checkroll.daily.update</field> 
    <field name="inherit_id" ref="hr.view_employee_form" /> 
    <field name="type">form</field> 
    <field name="arch" type="xml"> 
     <form string="daily_update"> 
      <xpath expr="//field[@name='name']" position="after"> 
       <field name="kanganyname" /> 
      </xpath> 
     </form> 
    </field> 
</record> 

或

checkroll.daily.update.form 代碼checkroll.daily.update 表格

需要定義你要添加這個領域無論是使用XPath或字段標籤

希望這有助於
