Question

我收到了一个错误：

ProgrammingError: relation "_unknown" does not exist
LINE 1: SELECT "_unknown".id FROM "_unknown" ORDER BY "_unknown"."id...

我无法选择request_id Many2one字段。有关详细信息，请参阅我的代码：

class PurchaseOrder(models.Model):
    _inherit = 'purchase.order'

    request_id = fields.Many2one('purchase.request', string='Purchase request', track_visibility='onchange')

OpenERP的的.py

{
    'name': 'My Purchase',
    'description': '...',
    'author': 'me',
    'depends': ['purchase'],
    'application': True,
}

xml part：

               <group>
                    <field name="request_id"/>
                    <field name="origin" attrs="{'invisible': [('origin','=',False)]}"/>
                    <field name="company_id" groups="base.group_multi_company" options="{'no_create': True}"/>
                </group>

在我的网页上，我检查了技术 - >数据库结构 - ＆gt;字段 - ＆gt;字段名称：request_id。我发现Object Relation is _unknown。在我的代码中，我看到了一个关系： request_id = fields.Many2one（'purchase.request'，string =＆＃39;购买请求＆＃39;，track_visibility =＆＃39; onchange＆＃39;）

所以我不知道出了什么问题。

也许我的 openerp .py文件需要一些依赖。

我在 openerp .py文件中添加了产品相关性，现在我又出现了另一个错误：

Answer 1

没有内置应用程序可以安装＆purchase ;request＆＃39;，我认为你是从自定义模块继承模型。

如果是，则在 openerp .py：depends

中添加模块名称

字面上我在https://www.odoo.com/apps/modules/9.0/purchase_request/

中找到了一个模块

如果您使用此项，请在__openerp_.py文件中添加模块名称

{
    'name': 'My Purchase',
    'description': '...',
    'author': 'me',
    'depends': ['purchase','purchase_request'],
    'application': True,
}

Odoo Many2one错误：关系＆＃34; _unknown＆＃34;不存在
