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()

我也检查了后端表。它们正确创建并且文件也正确操作。请检查这个并告诉我问题是什么

这里显示我的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>

请检查您的函数代码。它不像 openerp 函数代码。
