从父选项卡获取详细信息的OpenRP onchange事件

Question

对不起，这是个初学者的问题。在

我在OpenERP中有以下表格：

付款表（父表）

---------------------------------
| ID | OR_DATE     | TRANS_TYPE |
---------------------------------
| 1  | 2010-10-15  | 1          |
---------------------------------
| 2  | 2010-10-30  | 2          |
---------------------------------
| 3  | 2010-10-15  | 1          |
---------------------------------

付款明细表（子表）

^{pr2}$

付款类型表（参考表）

-----------------------------------------
| ID  | DESCRIPTION      | ACCOUNT_CODE | 
-----------------------------------------
| 1   | Cash             | ACCCODE001   |
-----------------------------------------
| 2   | Check            | ACCCODE002   |
-----------------------------------------
| 3   | Credit Card      | ACCCODE003   |
-----------------------------------------

我在OpenERP中有两个课程，结构如下：

Python代码：

payment(osv.osv):
    """
    OpenERP Model : payment
    """

    _name = 'payment'
    _description = __doc__

    _columns = {
        'or_date': fields.date('OR Date'),
        'trans_type':fields.many2one('payment.type', "Transaction Type"),
        'oth_pymt_det_ids':fields.one2many('payment.detail', 'oth_pymt_id', 'Details'),
    }
class payment()

class payment_detail(osv.osv):
    """
    OpenERP Model : payment_detail
    """

    _name = 'payment.detail'
    _description = __doc__

    #onchange_description function goes here

    _columns = {
        'oth_pymt_id':fields.many2one('payment', 'Payment'),
        'description':fields.char('Description', size=100 ),
        'account_title_id':fields.char('Account Title', size=20),
        'amount': fields.float('Amount', digits=(16, 2)),
    }

payment_detail()

XML代码：

<record model="ir.ui.view" id="payment_form">
    <field name="name">Payments</field>
    <field name="model">payment</field>
    <field name="type">form</field>
    <field name="arch" type="xml">
        <form string="Payments">
            <group col="4" colspan="4">
                <field name="trans_type" />
                <field name="or_date" />                                              
                <field name="oth_pymt_det_ids" mode="tree" nolabel="1" colspan="4">
                    <tree string="Payment Details" editable="top">
                        <field name="description" on_change="onchange_description()"/>
                        <field name="account_title_id"/>
                        <field name="amount"/>
                    </tree>
                </field>
            </group> 
        </form>
    </field>
</record>

如何在自动从“payment”表中获取和打印详细信息的onchange_description类中添加一个onchange_description事件？在

提前谢谢！在

您可以使用父级参数。您可以在sale module（python file）中找到一个示例

在你的情况下，试着用

<field name="description" on_change="onchange_description(description, parent.or_date)"/>
