Some way to add global params? about rabl

[nesquena]

Here is what I think you want:

{
   users : [...], 
   per_page: 23,
   current_page: 1,
   pages_count: 10
}

Here is how I would achieve that in RABL using a 'null' root object:

object false
child @users do
  attributes :name # , ...
end
code(:current_page) { |m| @users.current_page }
code(:pages_count) { |m| @users.pages_count }
code(:per_page) { |m| @users.per_page }

Does that answer your question?

Thank you, exactly what I want!

Awesome glad to hear it. The 'null' object comes in handy for cases like this where you kind of need to build your own root node along with rendering a collection. I ran into a couple cases like this too so I added this syntax. Let me know if you have any other questions.

You would be first who will see my questions :)
Thanks one more time for this gem.

No problem, created it to scratch my own itch for a decent way to craft public APIs which are rarely as simple in my case as a to_json call with a 'methods' hash and an 'only'. Glad it can be useful for others too :)
