Question

I am following this really great tutorial. Now I would like to get the comments for a specific posting as JSON output.

Doing this for the posting is easy because it is just to call the .json. But how does it work with the comments?

Answer 1

So this is mostly sans-code, but the ideas should at least set you in the right direction.

To provide comments with their own route, first set up a route for comments in your routes.rb file, then create a show method in the comments controller (similar to the way you set it up for a posting). In the comments controller show method, just render the comment the same way you do for the posting.

It is a bit easier to just include comments along with the posting when requesting the json output. In the posts controller show method, use render :json => @posting.to_json(:include => :comment) (substitute @posting for the name of the Post object you find in the show method).
