哪位大侠来帮我看看这个问题 - CNode技术社区

mongodb数据为: { "id" : ObjectId("55d42b62676bda1c1c6a09ae"), "name" : "生活", "description" : "生活需要大爆炸", "type" : 1, "subtype" : [ ], "v" : 0 }

其数据结构为:

var typeScheMa = new ScheMa({
 name: String,
 description: String,
 type:Number,
 subtype:[{
 name: String,
 description: String,
 type:Number
 }]
});

现在我想新增subtype里面的记录,用mongose应该怎么写呢?

Modelxxx.update({/* query condition*/}, {$push:{subtype: {/* new element */}, {/* options, like upsert */}, function(error, result) {});
