odoo，使用 _prepare_invoice 在发票中添加 many2many

Question

我想在我的发票中添加 many2many 字段，但是当我使用 _prepare_invoice 方法时，我得到一个空字段并且 x_fleet_vehicle_invoice_rel table 中没有记录！所以希望有人能帮助我...

class SaleOrderInherited(models.Model): 
    _inherit = 'sale.order' 

    order_field = fields.Many2many('fleet.vehicle', 'x_fleet_vehicle_sale_order_rel', 'order_id', 'vehicle_id', string='Order Field ') 

    @api.multi 
    def _prepare_invoice(self): 
        res = super(SaleOrder, self)._prepare_invoice() 
        res['invoice_field'] = self.order_field 
        return res 


class AccountInvoiceInherited(models.Model): 
    _inherit = 'account.invoice' 

    invoice_field = fields.Many2many('fleet.vehicle', 'x_fleet_vehicle_invoice_rel', 'invoice_id', 'vehicle_id', string='Invoice Field')

Answer 1

尝试res['invoice_field'] = [(6, 0, self.order_field.ids)]
