Ember: this.modelFor is not a function (in component)

Question about the Ember method modelFor

My attempts to use this in a component have failed:

//info component

model(params){
return this.store.createRecord('info'); 
},

user: this.modelFor('user'),

this code breaks the entire app with the following error:

ember.debug.js:4875 Uncaught TypeError: this.modelFor is not a function

I find myself often wanting to use methods in components, or wanting to access multiple models in my component logic -- does anyone know a good resource to educate myself on these best practices?

Thanks!
