如何在odoo 14中通过继承自定义产品模板视图？

from odoo import models, fields

class CustomProductTemplate(models.Model):
    _inherit = 'product.template'

custom_field = fields.Char(string='Custom Field')

<odoo>
    <data>
        <record id="view_product_template_form_inherit" model="ir.ui.view">
            <field name="name">custom.product.template.form</field>
            <field name="model">product.template</field>
            <field name="inherit_id" ref="product.product_template_form_view"/>
            <field name="arch" type="xml">
                <!-- Add or modify fields in the form view -->
                <field name="custom_field" position="after">
                    <field name="list_price"/>
                </field>
            </field>
        </record>
    </data>
</odoo>

'data': [
    'views/custom_product_template_view.xml',
],
