Define a single format (or specific formats)

What if I want to access only JSON? I dont want XML to be available or whatever!

Make sure to have format :json. We might also need to weed out XML and TXT, I am not sure you can remove those by default - add to this issue anything unexpected that you're seeing after that.

Just wanted to pop in here and second this, specifically because it appears XML serialization is borked when responding with an entity, it just shows .to_s of the entity class and doesn't serialize it.

I need only json-support and don't know how to disable xml and txt formatting...

as a workaround i'll validate the request in a before_filter like:

      def validate_request!
        request.env["api.format"] = :json # force api to use json!
        respond_with_404! unless ["json", nil].include? params.format # only respond to json
      end

I've committed 733f7df which resets default content types when you call content_type. This makes it so as soon as you start defining your own content-types, the default ones are removed.

JSON-only API (everything else returns 406)

format :json
content_type :json, "application/json"

Both JSON and XML, default JSON.

format :json
content_type :json, "application/json"
content_type :xml, "application/xml"
