python - odoo 尝试从其他模块继承模型时抛出错误

Question

我正在尝试从 website_sale 模块继承 products.products，以更改那里的一些属性。但是有一个错误，当我尝试继承它时。来自我的模块的 models.py 的代码：

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

from odoo import models, fields, api


class imgtogif_r(models.Model):
    _inherit = 'product.product'
    _name = 'product.product'
#     _description = 'imgtogif_r.imgtogif_r'

#     name = fields.Char()
#     value = fields.Integer()
#     value2 = fields.Float(compute="_value_pc", store=True)
#     description = fields.Text()
#
#     @api.depends('value')
#     def _value_pc(self):
#         for record in self:
#             record.value2 = float(record.value) / 100

模块是使用 odoo 的脚手架方法制作的。服务器崩溃（波纹管是错误日志，在浏览器中是错误 500）仅在我尝试在我的 models.py 中添加 _inherit 时发生
