Question

我已经尝试过Odoo 9并希望更换＆＃34; Total＆＃34; field = amount_total，其中包含一个新字段，该字段是使用XPath表达式添加字段内容（sum_of_total）的结果，但它失败并且未返回任何结果。
这是我的XML代码：

<openerp>
    <data>
        <record id="purchase_order_form_training1" model="ir.ui.view">
            <field name="name">purchase.order.form1</field>
            <field name="model">purchase.order</field>
            <field name="inherit_id" ref="purchase.purchase_order_form"/>
            <field name="arch" type="xml">
                <field name="amount_tax" position="after">
                    <field name="down_payment" widget="monetary" options="{'currency_field':'currency_id'}"/>
                </field>
                <xpath expr="form1/sheet/page/group/field[@name='amount_total']" position="replace">
                    <field name="sum_of_total"/>
                </xpath>
            </field>
        </record>
    </data>
</openerp>

odoo日志没有向我显示任何语法错误。任何人都可以帮我确定根本原因吗？

请参阅下文，了解sum_of_total如何初始化

from openerp import models, fields, api, _

class purchase_order(models.Model):
    _inherit = "purchase.order"

    @api.one
    @api.depends('down_payment', 'amount_total')
    def get_total_after_dp(self):
        dp = self.down_payment
        tot = selt.amount_total
        tota = tot + dp
        self.sum_of_total = tota

    sum_of_total = fields.Float('Total Amount',
                                    compute='get_total_after_dp')

    down_payment = fields.Float('Down Payment')

Answer 1

采购订单表单视图中没有form1。试试这个：

<xpath expr="form/sheet/notebook/page/group/field[@name='amount_total']" position="replace">
     <field name="sum_of_total"/>
</xpath>

Answer 2

<xpath expr="//field[@name='amount_total']" position="after">
      <field name='sum_of_total'/>
</xpath>

字段使用xpath替换odoo
