我有一个带有一些默认行为的 mongo 文档

var thingSchema = new mongoose.Schema(
    things:
        first: {
            type: Boolean,
            default: false
        },
        second: {
            type: Boolean,
            default: false
        }
); 

var myThings = mongoose.model('Things', thingsSchema);

如果我先更新

myThings.update({things: {first: true}});

和输出Things

Things.find(function(err, things){
     console.log(things) // {things: {first: true}, {second: false}}
});

然后我更新第二个值

myThings.update({things: {second: true}});

当我再次输出时,我得到{things: {first: false}, {second: true}}了,而不是所需的{things: {first: true}, {second: true}}.

无需每次都传递firstsecondupdate,如何防止模型恢复到默认行为?
