Sails Js模型在数组子文档中设置atrributes

Question

我正在尝试在sails模型子文档中添加属性日期。但是给出错误。

{type:'array',model:'Recommendations'}

Recommendations.js

var Recommendations = {
attributes: {
    role : {type:'string'},
    user : {type:'string'},
    userName : {type:'string'},
    user_image : {type:'string'},
    user_status : {type:'string'},
    title : {type:'string'},
    description : {type:'string'},
    createdAt : {type:'date'},
 }
};
module.exports = Recommendations;

任何人都可以帮助我...
