PHP Fractal transformer return embedded data - php

Question

I'm trying to use Fractal for transforming API data output. This works for single items and collections, but I can't seem to get it working with embedded data. Unfortunately, I can't find lots of "how to's" on Fractal. I followed the info on the Fractal site, but it won't work. I'm using Laravel 4 as my framework.
This is what I have on my Transformer class:
protected $availableEmbeds = array(
'requirements'
);
public function transform(){ etc... }
public function embedRequirements(Regions $regions)
{
return $this->collection($regions->requirements, new RequirementsTransformer);
}
Than, inside my controller I have
$regions = Regions::with($this->eagerLoad)->get();
This gives me the result I want.
But when I pass this data to the transformer it doesn't provide the desired result:
return $this->respondWithCollection($regions, new RegionTransformer());
RespondWithCollection method
protected function respondWithCollection($collection, $callback)
{
$resource = new Collection($collection, $callback);
$fractalManager = new Manager();
$rootScope = $fractalManager->createData($resource);
//$rootScope = $this->fractal->createData($resource);
return $this->respondWithArray($rootScope->toArray());
}
This is the output:
{
"data": [
{
"id": 36218,
"name": "Netherlands",
"active": true,
"created": "2014-02-28 11:17:02"
}
],
"embeds": [
"requirements"
]
}
Where I was expecting "requirements" to be part of a relations key inside the "data" key.
Does anyone knows what I'm doing wrong?

Answer 1

I ran into this problem just yet. The solutions was
Transformer class:
public function embedRequirements(Regions $regions)
{
$requirements = $regions->requirements()->get();
return $this->collection($requirements, new RequirementsTransformer);
}
The get() made all the difference
$regions->requirements()->get();
