无法在 Odoo 13

编程问答 2022-05-24

问题描述

在过去的两天里，我一直在尝试在 odoo 13 中安装一个自定义模块。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（变量在该类确实存在），我在下面显示了错误。

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：

经过反复试验，我尝试安装一个使用 odoo-bin 脚手架创建的默认模块，但当我无法安装它时，我很惊讶。

我在安装默认模块时遇到的错误是与其他 odoo 包表发生冲突，因为我处于测试环境中，我尝试删除这些包，并且在尝试重新安装时出现了相同的错误，但使用了不同的包.我不知道为什么会发生这种情况，因为先验地，我的包只依赖于“基础”。

用脚手架创建的默认模块的代码：

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

Error:
odoo Server Error
Traceback (most recent call last):
  File "/opt/odoo/odoo/odoo/http.py",line 467,in load_modules
    env[model]._check_removed_columns(log=True)
  File "/opt/odoo/odoo/odoo/models.py",line 2447,in _check_removed_columns
    tools.drop_not_null(cr,self._table,row['attname'])
  File "/opt/odoo/odoo/odoo/tools/sql.py",params)
psycopg2.errors.UndefinedColumn: column "rows" of relation "product_packaging" does not exist

但是，表 borrar_borrar 确实被创建了：

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得很好。

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。我也试过将它们直接放在目录中，错误都是一样的。

解决方法

我找到了解决方案。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) 从另一个数据库读取数据，并且由于某种原因，它对我正在处理的数据库造成了某种干扰。当我移除 FDW 时，一切都按预期工作。
