Can't use my own model with content negotiation

[weierophinney]

Hi!

I got an API with content negotiation. For binaries resources, the caller don't know the mime type.
Typically, if it's a element in an HTML page, I can't specify headers.

When the resource GET method is called, the server knows its type, and I can return an ImageModel or PdfModel or whatever I need instead of HalEntity or HalCollection, but the RestController encapsulate my model into a new entity and a ContentNegotiationViewModel... :-/

Rest controller should bypass contentNegotiation if I want to use my own model.

I use a patch to bypass, setting headers in the resource

$this->getEvent()->getRequest()->getHeaders()->addHeaderLine('content-type', 'application/pdf');

I think it's not the best way...
