Return whole model translated

[RaJiska]

I'd like to know if there is a way to return a whole translated model (API scenario). Currently returning a model will result in the translatable JSON array to be returned.

This is a follow up on this issue (#196) and I'd rather like to know if there is some sort of native way of doing what was accepted as answer in the issue. Doing the toArray function requires to edit the content of function every time the model is modified, therefore adding unnecessary work.

Is there some way to return a translated model in an elegant way ?
