how to access a models data from a view in backbone.js

Question

I have a model named person:

 var person = Backbone.Model.extend({
      initialize: function(){
        console.log('cool');
      },
      defaults:{
          names:['a','k','d','s','h','t']
      }
    })

Now I have a view:

var person_view = Backbone.View.extend({
   model : person,
   output: function(){
      console.log(this.model.get('names'))
   }
});

Created an object of the view:

var obj = new person_view()

Try to access names:

obj.output()

But I got this error:

TypeError: Object function (){ parent.apply(this, arguments); } has no method 'get'

Can you show me how to do things properly?I've only just started getting to know backbone.js so please bear with me.

You have to initialize your Model before you could access it :

var person_view = Backbone.View.extend({
    initialize: function() {
        this.model = new person();
    },
    output: function(){
        console.log(this.model.get('names'))
    }
});

Instead of passing the model when you extend the view, you'll want to pass it when you construct a new view:

var person_view = Backbone.View.extend({
  output: function(){
    console.log(this.model.get('names'))
  }
});

var obj = new person_view({
  model : new person()
});

Your "person_view" can not access any model (which is expected by that view) ,as no model is created yet, when you are declaring "person_view" and calling its function. First make a model then pass it to view when declaring that "person_view".

var model_person_for_view= new person();
var obj = new person_view(model:model_person_for_view);
obj.output();
