Question

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()

我也检查了后台的表，它们创建得很正确，字段也处理得很好。请检查一下，告诉我问题出在哪里

这里是我的 view.xml 文件

    <record model="ir.ui.view" id="namelist_update_form">
        <field name="name">Name List Update</field>
        <field name="model">checkroll.namelist.update</field>
        <field name="type">form</field>
        <field name="arch" type="xml">
            <form string="namelist_update">
                <field name="date" />
                <field name="value" />
            </form>
        </field>
    </record>

    <record model="ir.ui.view" id="namelist_update_list">
        <field name="name">Name List Update</field>
        <field name="model">checkroll.namelist.update</field>
        <field name="type">tree</field>
        <field name="arch" type="xml">
            <tree string="namelist_update">
                <field name="value" />
            </tree>
        </field>
    </record>

    <record model="ir.actions.act_window" id="action_namelist_update">
        <field name="name">Name List Update</field>
        <field name="res_model">checkroll.namelist.update</field>
        <field name="view_type">form</field>
        <field name="view_mode">tree,form</field>
    </record>

Answer 1

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

我需要把结果以字典对象的形式返回，并且字典的键应该是那条记录的ID。只需替换我的函数。

要感谢Mr. Parth Gajjar，他在http://help.openerp.com论坛上提供了帮助。

Answer 2

请你检查一下你的函数代码。它看起来跟openerp的函数代码不太一样。

你可以看看这个问题的链接：如何在openERP 7中添加一个函数？
