test for a property in ember object

Question

Let's say:

Foo.user = Ember.Object.extend({
    username:null,
    name:null,
    loadData:function(data){
        _.each(data, function(value, key){
            console.log(this.hasOwnProperty(String(key)), key, String(key));
            console.log((String(key) in this));
            console.log(key in this.__proto__);
            console.log(_.has(this, key));
            ...
        });
    },
})

Where data is an Object ex. JSON

Is there any Ember way of testing or just a JS OO way??

Yes it is underscore... ;)

Ok, context error, my apologies...poor me.

Foo.user = Ember.Object.extend({
  username:null,
  name:null,
  loadData:function(data){
      _.each(data, function(value, key){
          console.log(this.hasOwnProperty(String(key)), key, String(key));
          console.log((String(key) in this));
          console.log(key in this.__proto__);
          console.log(_.has(this, key));
          ...
      }, this);
   },
})
