环回在查询中包含远程方法 [英] loopback include remote method in query

问题描述

我正在寻找一种在查询时包含远程方法结果的方法.

I am looking for a way to include the result of a remote method when I make a query.

例如:我正在查询客户模型.要包含相关模型，可以使用包含过滤器{ filter: { include: ['orders'] } }.

For example: I am querying Customer models. To include a related model you would use the include filter { filter: { include: ['orders'] } }.

返回结果之前，我需要对一些相关模型进行一些处理.

I need to do some processing on some related models before returning results.

我正在寻找的东西类似于猫鼬的虚拟财产.有可能吗?返回结果后，我是否必须为每个客户创建一个单独的请求?

What I am looking for is something akin to virtual properties from Mongoose. Is this possible or do I have to create a separate request for each customer after results returned?

推荐答案

您可以扩展模型类并使用getter函数添加属性，以便它将从其他持久属性中获取值.

You can extend the model class and add properties with getter function so that it will get values from other persisted properties.

例如:

module.exports = function(Person) {
  Object.defineProperty(Person.prototype, 
    "fullName", 
    {
      get : function() { return this.firstName + ' ' + this.lastName; }
    });
}
