Using accessors and mutators in Laravel json responses - php

Question

So I'm making an API that produces a json response instead of doing View::make('foo', compact('bar')).
With blade templating
My controller simply returns the Eloquent model for Users:
public function index()
{
return User::all();
}
protected function getFooAttribute()
{
return 'bar';
}
And my view will be able to use it, along with the foo attribute (which isn't a field in the user's table).
#foreach($users as $user)
<p>{{$user->name}} {{$user->foo}}</p>
#endforeach
With Angular JS + json response
However, now that I'm not using blade but rather grabbing the json and displaying it with Angular JS I'm not able to do this:
<p ng-repeat="user in users">{{user.name}} {{user.foo}}</p>
Is there a way to cleanly pack the json response such that I have:
[{"name": "John", "foo": "bar"}, ...]
Warning: I've never built an API before and I've only started programming/web dev last December. This is my attempt:
public function index()
{
$response = User::all();
foreach($response as $r)
{
$r->foo = $r->foo;
}
return $response;
}

Yeah there is, example:
return Response::json([User:all()], 200);
Usually you want more than that though..
return Response::json([
'error' => false,
'data' => User:all()
], 200);
200 is the HTTP Status Code.
To include the attributes you need to specify these attributes to automatically append onto the response in your model.
protected $appends = array('foo');
public function getFooAttribute()
{
return 'bar';
}
