What are different ways to insert a document(record) into MongoDB using Mongoose?

My current attempt:

var mongoose = require('mongoose');

var Schema = mongoose.Schema;



var notificationsSchema = mongoose.Schema({

    datetime : {

        type: Date,

        default: Date.now

    },

    ownerId:{

        type:String

    },

    customerId : {

        type:String

    },

    title : {

        type:String

    },

    message : {

        type:String

    }

});



var notifications = module.exports = mongoose.model('notifications', notificationsSchema);



module.exports.saveNotification = function(notificationObj, callback){

    //notifications.insert(notificationObj); won't work

    //notifications.save(notificationObj); won't work

    notifications.create(notificationObj); //work but created duplicated document

}

Any idea why insert and save doesn't work in my case? I tried create, it inserted 2 document instead of 1. That's strange.

The .save() is an instance method of the model, while the .create() is called directly from the Model as a method call, being static in nature, and takes the object as a first parameter.

var mongoose = require('mongoose');



var notificationSchema = mongoose.Schema({

    datetime : {

        type: Date,

        default: Date.now

    },

    ownerId:{

        type:String

    },

    customerId : {

        type:String

    },

    title : {

        type:String

    },

    message : {

        type:String

    }

});



var Notification = mongoose.model('Notification', notificationsSchema);





function saveNotification1(data) {

    var notification = new Notification(data);

    notification.save(function (err) {

        if (err) return handleError(err);

        // saved!

    })

}



function saveNotification2(data) {

    Notification.create(data, function (err, small) {

    if (err) return handleError(err);

    // saved!

    })

}

Export whatever functions you would want outside.

More at the Mongoose Docs, or consider reading the reference of the Model prototype in Mongoose.
