Loopback同构客户端访问相关模型

Question

我想使用Loopback同构客户端为给定公司获取配置文件。

公司模型利用MySQL连接器和配置文件存在于ElasticSearch实例中。

环回客户端我的前端应用程序内正常使用，下面的代码成功运行：

let lbclient = window.require('lbclient') 
 

 
lbclient.models.RemoteProfile.find().done(profiles => { 
 
    // do something with the profiles array 
 
})

我的目标是作为一个嵌套的资源获取模式：

/api/companies/{id}/profiles/

问题是：为什么下面的代码在客户端上不起作用？

// This is the code I execute on the client 
 
lbclient.models.RemoteCompany.findById(8, (err, company) => { 
 
    company.profiles // undefined 
 
}) 
 

 
// This code works very well on the server 
 
Company.findById(8, (err, company) => { 
 
    company.profiles((err, profiles) => { 
 
    // profiles belong the the company having id=8 
 
    } 
 
})

您需要在查询配置文件是这样的：

lbclient.models.RemoteCompany.findById(8, {include: 'profiles'}, (err, company) => { 

})
