“升级模块”上自定义模块的Odoo 8 KeyError

Question

我有一个相关的字段设置，并在开发人员模式下通过GUI将字段添加到FormView时工作正常。但是，当我将字段添加到自定义模块并尝试执行升级时，它会在x_work_order_num上的KeyError中断。我错过了什么？

其他一些说明：

• odoo-server在更改为.py后重新启动
• 字段存在于设置>数据库结构>模型和字段中
• 通过Edit FormView（开发人员模式）向FormView添加x_rel_order和x_ext_num，但通过本地模块升级会引发上述错误。
• 在“onchange”方法实现之前发生错误。

Answer 1

不完全是某些人可能正在寻找的东西但在我的情况下，我所需要的是通过替换定义来解决的

x_ext_num = fields.Char(related='x_rel_order.x_work_order_num', string ="External Number")

同

x_ext_num = fields.Char(string='External Number', compute='_compute_x_ext_num')

我不需要相关选项，并将XML中的on_change绑定到方法：

@api.multi
def onchange_x_rel_order(self, order_id, context=None):
    ext_num = ''

    if(order_id):
        p = self.env['sale.order'].browse(order_id)
        ext_num = p.x_work_order_num

    res = {
            'value': {
                'x_ext_num': ext_num
          }
    }

    return res


def _compute_x_ext_num(self):
    for record in self:
          p = self.env['sale.order'].browse(record.x_rel_order.id)
          record.x_ext_num = p.x_work_order_num
