猫鼬：更新字段，推入数组中的对象[重复]

Question

我想在mongo数据库的数组中添加一个元素：

db.keypairs.update( {pubkey: "1234567890"}, { $push: {listTxId: {txHash: "yyy", spent: false} } } )

结果很完美：

listTxId" : [ { "txHash" : "xxx", "spent" : true },{ "txHash" : "yyy", "spent" : false } ]

var res = wait.forMethod(Keypair,'update', {pubkey: "1234567890"}, { $push: { "listTxId": {"txHash":"zzz", "spent":false} } } );

var Keypair = require('./app/models/Keypair');

var wait = require('wait.for');

{ "txHash" : "zzz", "spent" : false, "_id" : ObjectId("56561571fea5d9a10a5771fd") }

更新：猫鼬模式：

var keypairSchema = mongoose.Schema({
    userId      : { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
    pubkey      : String,
    privkeyWIF  : String, // temp
    balance     : Number,
    listTxId    : [{
        txHash : String,
        spent  : Boolean
     }],
    walletId    : { type: mongoose.Schema.Types.ObjectId, ref: 'Wallet' },
    description : { type: String, maxlength: 40 },
    comments    : String,
    isMasterKey : { type: Boolean, default: false },
    date        : Date
});

Mongoose将把ID放在子文档数组中。listtxid是子文档数组。您可以将_id:false添加到架构中以防止出现这种情况：

var keypairSchema = mongoose.Schema({
    userId      : { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
    pubkey      : String,
    privkeyWIF  : String, // temp
    balance     : Number,
    listTxId    : [{
        _id: false,
        txHash : String,
        spent  : Boolean
     }],
    walletId    : { type: mongoose.Schema.Types.ObjectId, ref: 'Wallet' },
    description : { type: String, maxlength: 40 },
    comments    : String,
    isMasterKey : { type: Boolean, default: false },
    date        : Date
});
