How do I get the substring of a JSON output?

Question

I want to render a simple JSON from an array.

array = ["valueid",true]
render :json=>array

which returns:

{"json":["valueid",true]}

but I don't want the JSON. The only part I want is:

["valueid",true]

Is there a simple way?

Answer 1

Yep:

get :index do
  [:id, 4].to_json
end

Better:

get :index, :provides => :json do
   my_array.to_json
end
