如何从odoo中的当前表单视图中获取记录到向导中？

Question

我在采购订单表单视图中添加了一个名为退货的按钮，该按钮显示了一个向导视图，我可以将产品退回到它，一切正常，但我需要知道如何获得自我采购订单的产品线，

class returnfromorder(models.TransientModel):
_name = 'returnfromorder'


picking_id = fields.Many2one('stock.picking')
product_return_moves = fields.One2many('stock.return.picking.line', 'wizard_id', 'Moves')
move_dest_exists = fields.Boolean('Chained Move Exists', readonly=True)
original_location_id = fields.Many2one('stock.location')
parent_location_id = fields.Many2one('stock.location')
location_id = fields.Many2one(
    'stock.location', 'Return Location',
    domain="['|', ('id', '=', original_location_id), ('return_location', '=', True)]")

@api.multi
def buto(self):
    products=self.env['purchase.order'].order_line
    for product in products.search([]):
        pro = product.product_id
        print(pro)

我在表单视图的按钮中使用了 methode buto，因此我可以在将值添加到行中之前测试和打印值

这里是 XML

    <!-- Inherit Form View to Modify it -->
    <record id="wizard_return_form" model="ir.ui.view">
        <field name="name">wizard.return.form</field>
        <field name="model">returnfromorder</field>
        <field name="arch" type="xml">
            <form string="return">
                <sheet>
                    <group>
                        <field name="picking_id"/>
                        <field name="product_return_moves"/>
                        <field name="move_dest_exists"/>
                        <field name="original_location_id"/>
                        <field name="parent_location_id"/>
                        <field name="location_id"/>
                        <button name="buto" class="oe_highlight" type="object" string="ObjectButton"/>
                    </group>
                </sheet>
                <footer>
                    <button string="Skip" class="btn-secondary" special="cancel"/>
                </footer>
            </form>
        </field>
    </record>

    <act_window id="return_wizard"
                name="Add return"
                res_model="returnfromorder"
                view_mode="form"
                target="new"
                view_id="wizard_return_form"
    />

任何帮助将不胜感激

您可以从上下文中获取向导中的当前记录 ID。

例如：

self._context.get('active_ids', [])

之后，您可以浏览这些记录，例如

for purchase in self.env['purchase.order'].browse(self._context.get('active_ids', []))
    XXXXXX
    execute your logic
