无法在 Odoo 13 中安装自己的自定义模块

Question

在过去的两天里，我一直在尝试在 Odoo 13 中安装自定义模块。我一遍又一遍地遇到同样的错误，告诉我正在创建的模型中不存在列（ class 中的变量确实存在），我在下面显示错误。

模块的python代码如下：

from odoo import models, fields, api

class OfferStage(models.Model):
    _name = 'offer.stage'
    _description = 'Offer stage'

    name = fields.Char()
    revisable = fields.Boolean()
    sequence = fields.Integer()
    modificable = fields.Boolean()
    notify_jefe = fields.Boolean()
    fold = fields.Boolean()
    convertible = fields.Boolean()
    notify_personal = fields.Boolean()
    notify_jefe_area = fields.Boolean()

我得到的错误是：

经过一些尝试和错误后，我尝试安装一个使用 odoo-bin 脚手架创建的默认模块，令我惊讶的是我都没有安装它。

我在安装默认模块时遇到的错误是与其他 table 的 odoo 包冲突，因为我在测试环境中，我尝试删除这些包，并且在尝试重新安装时，相同出现错误但使用不同的包。我无法弄清楚为什么会发生这种情况，因为先验地，我的包裹仅取决于 'base'.

使用脚手架创建的默认模块代码：

# -*- coding: utf-8 -*-
from odoo import models, fields, api

class borrar(models.Model):
    _name = 'borrar.borrar'
    _description = 'borrar.borrar'

    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

我得到的错误：

但是，table borrar_borrar 确实创建了：

这只会发生在我创建的模块上，我已经从 github 和官方 Odoo 商店下载了几个模块，并且所有模块都安装完美。

注意：为了便于维护，我将模块放在 git 存储库中，并将它们软链接到 odoo 目录中的 custom-addons 文件夹。我也试过直接放在目录下，还是一样的错误。

Answer 1

我找到了解决办法。我写在这里以防将来有人遇到同样的问题。

问题是我有一个外部数据包装器 (FDW) 可以从另一个数据库读取数据，并且出于某种原因，它对我正在处理的数据库造成了某种干扰。当我删除 FDW 时，一切都按预期工作。
