Question

I have a collection of model objects that I am trying to return JSON for. E.G

@regions.to_json(:only => [:id, :name ])

that works fine.

If I try to use :

@regions.to_json(:only => [:friendly_id, :name ]) 

then nothing is returned for the friendly_id. The model does have:

has_friendly_id :name, :use_slug => true

So I am wondering what I am missing – or if I am not allowed to use
friendly_id’s in to_json?

Answer 1

Try using

@regions.to_json(:only => [:id, :cached_slug])
