这是我的错误信息

这是我的模块源代码：

class namelistupdate(osv.osv):

    def _invoiced_rate(self, cr, uid, ids, name, args, context):
        amount_untaxed = 1
        if amount_untaxed == 0:
            res = 100.0
        else:
            res = 50.0
        print (res)
        return res

    _name = "checkroll.namelist.update"
    _description = "This table is for keeping Name list updates"
    _columns = {        
        'date': fields.date("Date"),
        'value': fields.function(_invoiced_rate, method=True, type='float', string='Test', store=True),
    }

namelistupdate()

我已经在后端表格中检查过了，它们被正确地创建并且字段也被正确地操作了。请检查一下这个问题，并告诉我问题所在。

这里展示了我的view.xml文件

    <record model="ir.ui.view" id="namelist_update_form">

                <field name="value" />
            </form>
        </field>
    </record>

    <record model="ir.ui.view" id="namelist_update_list">

错误已经很清楚了，你必须在执行 result.get(id) 之前将一个浮点值分配给 result。另外，你能展示一下产生错误的代码吗？ - avasal
@avasal：我认为这就是问题所在；因为它在OpenERP包内部，所以这可能是该平台的一个错误。 OP代码中没有任何迹象表明原因。 - Martijn Pieters

我注意到 _invoiced_rate 返回了一个浮点值。也许预期它应该返回一个映射？ - Martijn Pieters
感谢您尽早回复。我在这里定义了一个变量res，与其他部分无关。编写这段代码是因为我想了解如何检查函数字段的工作原理。谢谢！ - Priyan Changd

def _invoiced_rate(self, cr, uid, ids, name, args, context):
    amount_untaxed = 1
    record_id=ids[0]
    res={record_id: 0.0}
    if amount_untaxed == 0:
        res[record_id] = 100.0
    else:
        res[record_id] = 50.0
    print (res)
    return res

我需要以字典对象的形式返回结果，键应为该记录的id。只需替换我的函数。
