OpenERP 6.1：如何在account.move.line中创建新的树视图

Question

我在OpenERP 6.1中的account.move.line对象中创建了一个新的树视图时出现问题。

在新模块（account_summary）中，我有以下文件：

account_summary.py

from osv import fields,osv  
class account_summary(osv.osv):
    _inherit = "account.move.line"
    _name = "account.move.line"
    def _get_balance_inv(self, cr, uid, ids, field_name, arg, context=None):
        if context is None:
            context = {}
        lines_obj = self.browse(cr,uid,ids,context=context)
        result={}
        for line in lines_obj:
            result[line.id]= line.balance*(-1)
        return result
    _columns = {
        'balance_inv':fields.function(_get_balance_inv, string="balance inverso"),
    }
account_summary()

account_summary.xml

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <record id="view_account_summary_tree" model="ir.ui.view">
            <field name="name">account.summary.tree</field>
            <field name="model">account.move.line</field>
            <field name="type">tree</field>
            <field name="arch" type="xml">
                <tree string="Vista de resumen de cuentas">
                    <field name="balance_inv"/>
                </tree>
            </field>
        </record>

        <record id="action_view_account_summary_tree" model="ir.actions.act_window">
            <field name="name">Abrir resumen de cuentas</field>
            <field name="res_model">account.move.line</field>
            <field name="view_type">form</field>
            <field name="view_mode">tree</field>
            <field name="view_id" ref="view_account_summary_tree"/>
        </record>

        <menuitem id="menu_account_summary1" name="Resumen de cuentas" sequence="4" parent="account.menu_finance_reporting"/>
        <menuitem action="action_view_account_summary_tree" icon="terp-graph" id="menu_account_summary2" parent="menu_account_summary1" sequence="1"/>
    </data>
</openerp>

我正确安装模块但是当我点击创建的新菜单时，它会触发account.move.line对象的默认树视图，而不是仅使用新字段创建的新树视图。

任何帮助评论？

谢谢

我回答我自己的问题：

问题解决了在下一个字段中添加操作：

<field name="context">{'view_mode': True}</field>
