Cart.beforeRemote('*.__destroyById__products', function(ctx, cart, next) {
}）;
如何在上面的远程钩子中添加where子句，例如后面的
ctx.args.filter.where = {"id_product_attribute": id_product_attribute};
id_product_attribute是相关型号产品中的一个字段。
此处，id_product_attribute是产品关系中的一个字段，映射到CartProduct模型。 上面的远程钩子在Cart模型中使用，我需要以某种方式将where子句应用于CartModel上下文中的CartProduct上下文。我还附上了cart.json和cart-product。 json供参考。
