换货 的实现

[wjfonhand]

客户要求退货后直接生成退回单，在OpenERP7.0上做了简单的开发：

<record id="ssf_view_stock_return_picking_form" model="ir.ui.view">
            <field name="name">ssf.ssf_view_stock_return_picking_form</field>
            <field name="model">stock.return.picking</field>
            <field name="inherit_id" ref="stock.view_stock_return_picking_form"/>
            <field name="arch" type="xml">
                <button string="Cancel" position="after">
                    <button name="create_change" string="换货" type="object" class="oe_highlight"/>
                </button>
            </field>
        </record>

class stock_return_picking(osv.osv_memory):
    _inherit = 'stock.return.picking'

    def create_change(self, cr, uid, ids, context=None):
        res = self.create_returns(cr, uid, ids, context=context)
        # it is build like this:
        # 'domain': "[('id', 'in', ["+str(new_picking)+"])]",
        new_id = int(eval(res['domain'])[0][2][0])
        ctx = context.copy()
        ctx.update({'active_id':new_id})
        change = self.create_returns(cr, uid, ids, context=ctx)
        return res
