Removing node from RABL

Question

I'm new to rails and I'm trying to create an API for my application. I'm also using rabl for generating my JSON responses. In my rabl template I want to send a timestamp and a collection of items.

The code looks like this:

object false
node(:timestamp){CourseType.maximum("updated_at")}
child(@course_types){attributes :id, :name, :deleted}

And I want to get an object that would look like this:

{"course_types":
    [{"id":2,"name":"Driving","deleted":false},
     {"id":4,"name":"Cooking","deleted":false}],
 "timestamp":"2016-04-25 16:22:57 UTC"}

However I'm getting this instead:

{"course_types":
    [{"course_type":
        {"id":2,"name":"Driving","deleted":false}},
     {"course_type":
        {"id":4,"name":"Cooking","deleted":false}}],
 "timestamp":"2016-04-25 16:22:57 UTC"}

Any ideas on how to solve this?

Thanks

Rabl allows you to control these children root nodes across all views via an initializer

https://www.digitalocean.com/community/tutorials/scaling-ruby-on-rails-setting-up-a-dedicated-mysql-server-part-2

and then setting the correct combination of the configurations

# config/initializers/rabl_init.rb
require 'rabl'
Rabl.configure do |config|
  config.include_json_root = true
  config.include_child_root = false  
end
