Question

我在Odoov9社区版中为自定义模块添加了一个字段。

像这样：

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.'),
}

但是当服务器加载时，它会抛出这个错误：

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

有人能说清楚这个吗？

我对此非常困惑，之前从未遇到过此错误。

如果您继承了已定义的模块，则无需定义_name变量，只需定义_inherit变量也可以。

您收到的错误是“模块没有attrbiute many2one”，因为您为新api导入了fields，但是将其定义为旧api方式。如果在新api中编写代码，也应解决最大递归错误。

如果您正在为Odoo 9编写此模块，那么在新的API中编写它是个好主意。以下是使用新api编写的代码：

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.')

上面的代码应该没有任何问题。
