首先，这是我的迁移脚本：

const bluebird = require("bluebird");
const mongoose = require("mongoose");
mongoose.Promise = bluebird;
mongoose.connect("mongodb://localhost:27017/app", { useMongoClient: true    });

const schema = {    
    uid: {  
        type: String,   
    },  

    parentID: { 
        type: String,   
    },  

    name: { 
        type: String,   
    },  

    displayName: {  
        type: String,   
    },  

    createdAt: {    
        type: Date, 
    },  

    modifiedAt: {   
        type: Date, 
    }   
};  

const FolderSchema = new mongoose.Schema(schema);   
const FolderModel = mongoose.model("folders", FolderSchema);    


// initial folders  
const folders = [   
    { uid: "", parentID: "", name: "folder1", displayName: "Folder 1" }, …
