rails render :json method

Question

I have a query regarding rails render method.

If I have something like->

hashObj = {"a"=> 1, "b"=>2}
render json: hashObj

then I know that render method will internally call JSON.dump(hashObj) to get the json to render.

However I want to use my own custom library (e.g. Oj) to create json, can I do something like this:

hashObj = {"a"=> 1, "b"=>2}
render json: Oj.dump(hashObj, mode: :compat)

How will render method behave here ? Will it check that we are already passing it a json string and hence it does not need to call JSON.dump now ?

I did, but its a bit confusing, hence wanted to clarify it further here on StackOverflow. — snow_leopard

You're right, Rails won't attempt to convert what ever you pass to the json option if it's some kind of a string, as you can see here.
