node.js - Mongoose 默认带 findOneAndUpdate

Question

我有以下架构:

var UserSchema = new Schema({
  username: { type: String, required: true, unique: true },
  displayName: { type: String, required: true },
  registered: { type: Boolean, required: true, default: false }
});

然后我尝试使用 findOneAndUpdate 插入和对象:

  var user = {
    displayName: "Test User"
  }

  User.findOneAndUpdate({username: "test"}, user, {new: true, upsert: true}, function(err, newUser) {
    callback(err, newUser);
  });

用户被正确创建(第一次尝试，因为它不存在)。但是注册字段不会设置为 false。当我执行 findOneAndUpdate 时会发生这种情况吗？

mongo查询结果:

> db.users.find().pretty()
{
    "_id" : ObjectId("56255f415641ace1204de658"),
    "username" : "Test",
    "displayName" : "Test User"
}

Answer 1

在 Mongoose 文档中找到了这个:

findAndModify helpers support limited defaults and validation. You can enable these by setting the setDefaultsOnInsert and runValidators options, respectively.

以防其他人遇到这种情况。

 var user = {
    displayName: "Test User"
  }

  User.findOneAndUpdate({username: "test"}, user, {setDefaultsOnInsert: true, new: true, upsert: true}, function(err, newUser) {
    callback(err, newUser);
  });
