自定义Odoo模块添加子类后安装错误

Question

我试图在制造模块的产品屏幕上添加一个选项卡。标签应该是这样的:Product Part Detail标签

我创建了一个自定义模块，当我试图安装它时，我一直得到一个错误:"ParseError:"ValidateError字段arch违反约束失败:无效的视图定义错误的细节:字段x_mfrpn不存在"

下面是我的代码，我意识到这是OpenERP的新版本的语法，但在我试图添加"类sub_part_detail"之前，该模块工作正常。

from openerp.osv import osv, fields
class product_part_detail(osv.osv):
_name = 'product.part.detail'
_inherit = 'product.template'
_columns = {
'x_mfrpn': fields.char('P/N'),
    'product_part_detail': fields.one2many('sub.part.detail','sub_part_detail')
}
class sub_part_detail(osv.osv):
_name = 'sub.part.detail'
_inherit = 'product.part.detail'
_columns = {
    'x_bomcategory': fields.char('Category'),
'x_primarypn': fields.boolean('Primary PN'),
'x_obsolete': fields.boolean('Obsolete'),
'x_mfrname': fields.char('MFR'),
'x_pndescription': fields.char('Description'),
'x_pnupgrade': fields.char('Upgrade'),
'x_pnnotes': fields.text('Notes'),
    'sub_part_detail': fields.many2one('product.part.detail')
}

这是我的xml

<?xml version="1.0"?>
<openerp>
<data>
    <record model="ir.ui.view" id="product_part_detail">
        <field name="name">product.template.product.form</field>
        <field name="model">product.template</field>
        <field name="inherit_id" ref="product.product_template_only_form_view"/>
        <field name="arch" type="xml">          
            <xpath expr="//page[@string='Accounting']" position="after">
                <page string="Part Detail">
                    <field name="x_mfrpn" />                        
                </page>       
            </xpath>
        </field>
    </record>   
    <record model="ir.ui.view" id="sub_part_detail">
        <field name="arch" type="xml">          
            <field name="x_mfrpn" position="after">
                    <field name="x_bomcategory" />
                    <field name="x_primarypn" />
                    <field name="x_obsolete" />
                    <field name="x_mfrname" />
                    <field name="x_pndescription" />
                    <field name="x_pnupgrade" />
                    <field name="x_pnnotes" />                        
            </field>
        </field>
    </record>   
</data>

        <record model="ir.ui.view" id="sub_part_detail">
            <field name="name">sub.part.detail..form</field>
            <field name="model">sub.part.detail</field>
            <field name="arch" type="xml">                              
                <field name="x_bomcategory" />
                <field name="x_primarypn" />
                <field name="x_obsolete" />
                <field name="x_mfrname" />
                <field name="x_pndescription" />
                <field name="x_pnupgrade" />
                <field name="x_pnnotes" />                                        
            </field>
        </record>   

也不需要写_inherit = 'product '。模板",_inherit = 'product.part.detail' in py file
