如何正确使用Mongoose模型？

I try to save the some information in to Mongo with Mongoose, but nothing happens… My code is :

我尝试用Mongoose将一些信息保存到Mongo中，但没有任何反应......我的代码是：

function User() {
    console.log(_db.version);

    var user_schema = new _db.Schema({ 
        'email': { 'type': String, 'required': true, 'lowercase': true, 'index': { 'unique': true } },
        'password': { 'type': String, 'required': true },
        'name': {'type': String, 'required': true},
        'age': {'type': Date},
    }, {'collection': 'users'});

    var user_model = _db.model('user', user_schema);

    this.createNew = function(name, age) {
        console.log('createNew');

        var new_user = new user_model({'name': name, 'age': age});

        new_user.save(function(err){
            console.log(err);
            console.log('Save function');
        });
    }
}

var user = new User();
user.createNew('Tom', 21);

In the result i just get 3.8.1 createNew.

在结果中我得到3.8.1 createNew。

I suggest you change your approach a bit, try this out:

我建议你改变一下你的方法，试试看：

var UserSchema = new Schema({
    email: {
        type: String,
        required: true,
        lowercase': true,
        index: {unique: true},
    },
    password: {type: String, required: true},
    name: {type: String, required: true},
    age: {type: Date},
})

UserSchema.statics.createNew = function(email, password, name, age, next) {
    var user = new this({  
        email: email,
        password: password,
        name: name,
        age: age
    })
    user.save(next)
}

mongoose.model('User', UserSchema)

Now you can create a new User by:

现在您可以通过以下方式创建新用户：

var User = mongoose.model('User')
User.createNew('tom@gmail.com', 'password', 'Tom', 21, function(err, user) {
    ...
})

Added email and password as arguments because the Schema says that they are required.

添加了电子邮件和密码作为参数，因为Schema说它们是必需的。

#2

I don't see you assigning values to email and password fields of the schema.

我没有看到您为模式的电子邮件和密码字段分配值。

required: {Boolean} - If true, creates a validation rule requiring this path be set before saving occurs.

required：{Boolean} - 如果为true，则创建一个验证规则，要求在保存之前设置此路径。
