Subresource endpoint

[jpkleemans]

Lets say I have the following endpoint: /authors/{author_id}/books/{book_id}. How can I create the output for this endpoint with Fractal, and keeping the correct links?

I was thinking about something like:

$item = new Item($book, $bookTransformer, 'authors.books');

But this outputs /authors.books/{book_id} as self-link. Which makes sense when you see https://github.com/thephpleague/fractal/blob/master/src/Serializer/JsonApiSerializer.php#L77

I don't think this is the idea. You are returning a link to the actual resource so just books.

This way you get the correct link of /books/{book_ID}

I think this fine to do. I've seen many APIs that do this. It's situational of course but you should be able to do this.

I ended up created a propietaryJsonApiSerializer, that does two things:

1. It allows me to set the resource key in the transformer, simply because having to add in the resource key for every single item/collection call seems really shitty.

2. I added a check for the data array. If it includes _resourceAddress, then I use that instead of the auto generated $resourceKey/$id links.
