Python 如何从web_studio继承模型

我在

web\u studio

->

x\u shippingcountries

中创建了一个模型，我想继承这个模型，但这不起作用。不会调用任何方法

设置：Odoo13

我在

\uuuu manifest\uuuuu.py

depends': [
    'base',
    'idx_elasticsearch',
    'web_studio'
],

我在奥多13的模特

# -*- coding: utf-8 -*-

from odoo import models, api

class ShippingCountries(models.Model):
    _inherit = 'x_shippingcountries'

    @api.model
    def create(self, vals):
        # hook creation
        _logger.debug("Settings Countries: Queue.hook.create")
        res = super(ShippingCountries, self).create(vals)
        return res

    def write(self, vals):
        # hook writing
        _logger.debug("Settings Countries: Queue.hook.write")
        res = super(ShippingCountries, self).write(vals)
        return res

    def unlink(self):
        # hook deletion
        _logger.debug("Settings Countries: Queue.hook.unlink")
        return super(ShippingCountries, self).unlink()
