在嵌套模式中从csv导入mongodb

Question

我有csv文件

日期，dynmSpecMeta.regNo，dynmSpecMeta.vehRegNumber，路径，distCovered，fuelConsumption 2017-10-02，AZRPN5786K，MH 32 AQ 3189，路线10,10.8,1.15 2017-10-02，AYHPN5745L，MH 31 AQ 3474，Route 7,18.5,2.59 2017-10-02，AZRPN5783D，MH 33 AQ 1684，Route 14,11,1.48 2017-10-02，AZRPN5951P，MH 30 AQ 5833，路线8,5,0.68

这么多行...

我想将其导入已有的架构 -

var vahNityaSchema = new Schema({

updated: { type: Date, default: Date.now},

dynmSpecMeta: {
    date: Date,
    vehRegNumber: { type: String, required: false, unique: true},   // ref to vahAchar
    path: { type: String, required: false, unique: true},           // ref to vahPath
    regNo: { type: String, required: false, unique: true},          // ref to vahSarthi

    distCovered: Number, 
    fuelConsumption: Number,
}

}）

我无法使用简单的mongoimport将其导入嵌套架构.... 请帮忙......
