期望的单例: stock.move - Odoo v9社区

Question

我使用以下方法从fleet_vehicle_log_services创建一个stock.picking：

@api.multi
def create_picking(self):
    self.ensure_one()
    vals = {
        'move_lines': self.move_lines.id,
        'origin': self.name
    }
    picking = self.env['stock.picking'].create(vals)
    return picking

在fields上声明如下：

move_lines = fields.One2many('stock.move', 'picking_id', string="Stock Moves", copy=True)

我的观点是：

    <group string="Datos del picking">
       <button name="create_picking" string="Crear Picking" type="object" class="oe_highlight"/>
                        <tree>
                            <field name="move_lines" string="Lineas"/>
                            <field name="state" invisible="1"/>
                        </tree>
                </group>

当我单击create the picking时，它会抛出以下内容：

有什么想法吗？

Answer 1

One2many字段需要特殊命令才能插入。在您的案例中：

 vals = {
        'move_lines': [(6, 0, self.move_lines.ids)],
        'origin': self.name
    }
