How do i find if the model is new or has no property in it : backbone

Question

This is my backbone model and collection:

var myModel = Backbone.Model.extend({ });

var myCollection = Backbone.Collection.extend({
    model :  myModel,
});

when i do new of model

debitRow = new myModel();

this will have no property or value in it.

now how do i find that the model is empty or not

Answer 1

I have made it to work like the following,

if(_.isEmpty(debitRow.attributes)){
                        // do your stuff
                    }
