This is such a simple “helper” but I love using it.  Specially when I am working with nested objects or don’t like the naming conventions of server-side model.  You can use computed.alias to alias another property.
Example 1:
Your model has a property called FirstName but you want to use firstName in your views and controller, you could add an alias:

You can get and set firstName the same way as model.FirstName.  It’s a nice shortcut.
Example 2:
If you have a nested model that has a profile object which has a gravatar object which has a Url property then accessing that property is PITA with this.get(‘model.profile.gravatar.url’) or in the view with {{model.profile.gravatar.url}}.  Instead add an alias to your controller:

And now you can simply, do this.get(‘gravatarUrl’) or {{gravatarUrl}}

That’s it for today!

Let me know what you think of today’s tip.  Thanks.
