javascript - 如何在 Mongoose 中排除 "upsert-ed"字段？

Question

var UserData = function(){
    var self = this;
    this.schema = Schema({
        userID: String,
        firstName: String,
        lastName: String,
        ...
        //many other fields.
        ...
        isActive: {type: "Boolean", default: true}
    },  { collection: 'UserData' });

    this.model = db.model('UserData', self.schema);

    this.upsert = function(object){
        //some logic
        self.model.update({userID: object.userID}, object, {upsert: true}, function(err){...});
    };
}

此代码工作正常，除了 isActive 将在更新插入期间被覆盖。

我想实现这样的逻辑:

1. 对于新记录，默认 isActive 为 true。
2. 更新插入时，保持isActive不变。

如何实现这一目标？提前致谢!

将文档转换为对象并删除您不想写入的属性。然后更新插入对象。

this.upsert = function (doc) {
    var object = doc.toObject();
    delete object.isActive;

    self.model.update({userID: object.userID}, object, {upsert: true}, function(err){...});
};
