javascript-MongoDB对象类型未保存

(javascript - MongoDB object type is not saved)

发布于 2020-11-28 07:28:06

我的用户架构如下。

var userSchema=mongoose.Schema({
    //name:{type:String},
    username: {type:String, required:true, unique:true},
    password: {type:String, required:true},
    habit: {type:Object, required:true}
});

但是，当我将新用户（新手）保存到mongoDB时，仅习惯字段未保存。

var newbie=new User({
    username:username,
    password:password,
    habit:{}
});
console.log(newbie);

console.log（newbie）的结果是“ {_id：~~~ ????，用户名：'babo'，密码：'1234'}”，其中不包含习惯字段...我该如何添加习惯？

默认情况下，mongo不保存空对象。因此，如果要保存一个空对象，则必须将第二个参数{ minimize: false }传递给Schema。

使用此代码。这应该可以解决你的问题。

var userSchema=mongoose.Schema({
    //name:{type:String},
    username: {type:String, required:true, unique:true},
    password: {type:String, required:true},
    habit: {type:Object, required:true}
}, { minimize: false });
