Question

我有这段代码，如果该人在一个人中，则会获取销售团队的ID，否则它将返回None。

class AccountInvoice(models.Model):
    _inherit = 'account.invoice'

    xx_section_id = fields.Many2one('crm.case.section', string='Invoice template', required=True,
                                default=lambda self: self._get_sales_team())

    @api.model
    def _get_sales_team(self):
        ids = self.env['crm.case.section'].search([('member_ids', 'in', self._uid)])
        if len(ids) != 1:
            # Has no sales team or more than one
            return None
        return ids[0]

出于某种原因，这适用于我的本地环境，但不适用于服务器。我尝试安装模块时发生错误。服务器给我以下错误：

AttributeError: 'NoneType' object has no attribute 'id'

在记录中它说明：

2016-12-06 19:39:06,662 2005 ERROR None openerp.http: Exception during JSON request handling.

    raise NotFound()

我做错了什么？

Answer 1

对于案例len（ids）== 0，脚本会尝试返回ids [0]＆＃39;。

根据＆＃39; ID＆＃39;的结果值，您的条件应为：

if ids:

或

if len(ids) > 0:

Lambda导致AttributeError
