Loopbackjs 环回:如何访问afterRemote中的关系
我为车辆段模型设置了以下afterRemote方法:Loopbackjs 环回:如何访问afterRemote中的关系,loopbackjs,Loopbackjs,我为车辆段模型设置了以下afterRemote方法: Depot.afterRemote('find', function(context, depots, next) { context.result.forEach(depot => { console.log(depot.drivers); depot.address = depot.street_name + ' ' + depot.door_number;
Depot.afterRemote('find', function(context, depots, next) {
context.result.forEach(depot => {
console.log(depot.drivers);
depot.address = depot.street_name + ' ' + depot.door_number;
depot.driver_count = depot.drivers.length;
});
next()
})
在json响应中,depot.drivers包含正确的数据
然而,当我尝试使用上述方法访问depot.drivers时,我得到了一些奇怪的输出:
{ [Function: f]
_receiver: { postal_code: '1216BS',
door_number: '3',
street_name: 'Straat naam',
city: 'Hilversum',

我最终希望添加depot.drivers\u count属性,以便在前端表中显示连接到特定depot的驾驶员数量
有人知道怎么做吗?看起来数据没有转换成JSON 我想试试这个:
context.result.forEach(depot => {
depot = depot.toJSON();
console.log(depot.drivers);
depot.address = depot.street_name + ' ' + depot.door_number;
depot.driver_count = depot.drivers.length;
});
在环回中,可以使用回调函数访问每个模型关系,因为i/o是异步的。这样做:
depot.驱动程序((错误,驱动程序)=>{
//处理错误
//对司机做点什么
})
