用nodejs中的关联和排序对findAll进行续集答案

【问题标题】：sequelize findAll with association and ordering in nodejs用nodejs中的关联和排序对findAll进行续集

【问题描述】：

我正在尝试通过以下方式在 booking_date 之前获取所有用户及其主要供应商、预订和服务订单。

Users.findAll({
            where: { id: userId }, attributes: AttributesUser,
            include: [{
                model: MasterVendor, attributes: AttributesMasterVendor, required: true,
                include: [{
                    model: Bookings, where: { booking_state: jobStatus, booking_date: _date }, attributes: AttributesBooking,
                    include: [{ model: Services, attributes: attributesService, order: ['Bookings.booking_date'] }],
                }],
            }],
        });

但不幸的是，order by 子句根本没有生成。但是当我尝试按名称获取数据顺序时，它工作得很好

Users.findAll({
            where: { id: userId }, attributes: AttributesUser,
            include: [{
                model: MasterVendor, attributes: AttributesMasterVendor, required: true,
                include: [{
                    model: Bookings, where: { booking_state: jobStatus, booking_date: _date }, attributes: AttributesBooking,
                    include: { model: Services, attributes: attributesService }
                }]
            }],
            order: ['name'],
        });

请建议我，我做错了什么。谢谢。

【解决方案1】：

试试这个

在顺序数组中包含模型名称。

Users.findAll({
            where: { id: userId }, attributes: AttributesUser,
            include: [{
                model: MasterVendor, attributes: AttributesMasterVendor, required: true,
                include: [{
                    model: Bookings, where: { booking_state: jobStatus, booking_date: _date }, attributes: AttributesBooking,
                    include: { model: Services, attributes: attributesService }
                }]
            }],
            order: [[Bookings, 'booking_date', 'DESC']],
        });

【解决方案2】：

最后，我解决了这个问题。我必须在顺序数组中的子表（预订）之前添加父表（MasterVendor）

order: [[MasterVendor,Bookings, 'booking_date', 'ASC']],

最后，

Users.findAll({
            where: { id: userId }, attributes: AttributesUser,
            include: [{
                model: MasterVendor, attributes: AttributesMasterVendor, required: true, include: [{
                    model: Bookings, where: { booking_state: jobStatus, booking_date: _date }, attributes: AttributesBooking,
                    include: [{ model: Services, attributes: attributesService }],
                }],
            }],
            order: [[MasterVendor, Bookings, 'booking_date', 'ASC']],
        });
