loopback格式导致afterRemote挂钩

Question

我有两个型号Book.json和Department.json。当我获取书籍细节时，我们也通过关系获取相应的部门。 输出是：

[{
"title": "Python",
"department": {
    "name": "Software"
}
},
{
"title": "World",
"department": {
    "name": "Politics"
}
}]

我们如何将上述代码格式化为

[{
"title": "Python",
"department": "Software"
},
{
"title": "World",
"department": "Politics"
}]

当我尝试格式化 ctx.result 时，它会给我一个错误，例如只支持getter。

  

“message”：“无法设置只有getter的#ModelConstructor属性书”，

Answer 1

您可以使用Array#map循环浏览项目并修改迭代中的每个项目：

＆＃13;

＆＃13;

const data = [{"title":"Python","department":{"name":"Software"}},{"title":"World","department":{"name":"Politics"}}];

const result = data.map(item => {
  item.department = item.department.name;
  return item;
});

console.log(result);

＆＃13;

＆＃13;
