Question

From what I have read, I can respond to a json request by using the following code:

respond_to do |format|
  format.json { render json: t.response }
end

My problem is that t.response is already in json format – and I think that my app is breaking because render json: is re-converting it to json. How do I avoid this, and simply return t.response.

Note that if I simply have t.response as my last line in the controller, the corresponding view is rendered – which is obviously not json.

Thanks!

EDIT: I am trying to get this working so I can send sms via tropo. If you have used tropo before, do you have any suggestions how to respond back to tropo correctly?

Answer 1

I’ll show you how Rails deals with converting to json format. It’s basically on line:

json = json.to_json(options) unless json.kind_of?(String)

So, strings aren’t converted, other objects are converted to String via their to_json method. If your t.response returns a string then no conversion is performed.
