Handlebars template won't render ember data object - ruby-on-rails

Question

I've built an ember front-end app that consumes an API made with rails in another application. The ember app is successfully requesting and receiving data from the rails api and one of my handlebars template (the index page that displays a list of all of the Graduates from my Graduates model) is working fine. The page meant to display individual graduates however is not able to render data about those individual graduates. Although when I open the ember tool in the developer console in my browser (Chrome), that data is present.
I'm new to ember and I've been trying to solve this for 2 days but am totally stumped, any help would be greatly appreciated!

app/templates/graduate.hbs:
<h1>{{firstName}} {{lastName}}</h1>

Answer 1

Should be
// app/templates/graduate.hbs
<h1>{{model.firstName}} {{model.lastName}}</h1>
Your template
<h1>{{firstName}} {{lastName}}</h1>
shows firstName and lastName properties from current controller (class Ember.Controller), but they are not set.
