模塊沒有attrbiute many2one - Odoo v9社區

Question

我正在向Odoov9社區版的自定義模塊中的模型添加一個字段。

像這樣：

import logging 
from openerp import api, fields, models, _ 
from openerp.exceptions import UserError, ValidationError 
from openerp.tools.safe_eval import safe_eval as eval 

class refund(models.Model): 

"""Inherits account.invoice.refund and adds journal_id field""" 
    _name = "account.invoice.refund" 
    _inherit = "account.invoice.refund" 

    _columns = { 
     'journal_id': fields.many2one('account.journal', 'Refund Journal', help='You can select here the journal to use for the credit note that will be created. If you leave that field empty, it will use the same journal as the current invoice.'), 
} 

但是，當服務器負載，它將引發我這個錯誤：

AttributeError: 'module' object has no attribute 'many2one' 

任何人都可以在此揭示？

我對此很困惑，以前從未有過這個錯誤。

如果您繼承自已定義的模塊，則無需定義_name變量，只需定義_inherit變量即可。

當您爲新的api導入fields，但將其定義爲舊的api方式時，您收到錯誤「Module has not attrbiute many2one」。如果您在新的API中編寫代碼，最大的遞歸錯誤也應該得到解決。

如果您正在爲Odoo 9編寫此模塊，最好將它寫入新的api中。下面是你的代碼寫入新的API：

import logging 
from openerp import api, fields, models, _ 
from openerp.exceptions import UserError, ValidationError 
from openerp.tools.safe_eval import safe_eval as eval 

class refund(models.Model): 
_inherit = "account.invoice.refund" 

journal_id = fields.Many2one('account.journal', string='Refund Journal', help='You can select here the journal to use for the credit note that will be created. If you leave that field empty, it will use the same journal as the current invoice.') 

上面這段代碼應該沒有任何問題的工作。
