openerp学习笔记 视图中字段只变化(on_change)联动其他字段值、选择和过滤
1.修改产品数量时，自动计算产品销售金额、销售成本和销售利润
<field name="num" on_change="on_change_product(product, num, price)"/>
2.选择历史工单时，按销售单中当前选择的客户自动过滤，打开选择历史工单窗口时，过滤条件默认为销售单中当前选择的客户
<field name="work_order" domain="[('customer','=',customer)]" context="{'search_default_customer':customer}"/>
代码示例：
<!-- views dispatch_sale_form -->
<record model="ir.ui.view"
id="dispatch_sale_form">

name="name">dispatch.sale.form</field>
