Odoo继承修改tree视图的属性

如下所示，直接继承到指定的tree试图id，xpath定位到tree标签，直接修改tree试图的属性即可

    <record id="apm_tree_view_01" model="ir.ui.view">
        <field name="name">扩展视图Tree01</field>
        <field name="model">approve.xxx</field>
        <field name="inherit_id" ref="approve_notify.approve_main_tree_view"/>
        <field name="arch" type="xml">
            <xpath expr="//tree" position="attributes">
                <attribute name="default_order">urgent_sequence, approve_date desc, id desc</attribute>
        </field>
    </record>
    ```
