Add support of views or at least "rabl" about grape

[onethirtyfive]

I did some work on this

[amrnt]

I tried you branch, but I don't know why it didnt work. always returns { }

Did you initialize rabl per its instructions? All my patch does is get tilt in the stack. You'll still need to do RABL.initialize! (or whatever RABL requires, I don't recall) after your bundled gems are loaded, but before you 'run' your api. Give it a shot in config.ru?

Also, because the current implementation is pretty naive, you'll need to render by local variables, as detailed in the example. :)

Rabl need to be Rabl.register!.

resource :me do
  get do
    template 'user.rabl'
    { :user => current_user }
  end
end

In the same folder user.rabl

object user

attributes :_id, :display_name

Again when I go to /me All I get { }

Hi amrnt,

I committed some changes for some simple mistakes I made. I also made an example repository illustrating how this works after my changes.

progress going awesome! Thanks @onethirtyfive.

But there's an issue, (I have 7 items. And I want to How to output some random, not directly related items https://github.com/nesquena/rabl/wiki/Tips-and-tricks)

object false

child(@object) do
  attributes :_id, :caption, :created_at
end

node(:pagination, :unless => @object.blank?) do
  {
    :next => @object.next_page,
    :previous => @object.previous_page,
    :total_pages => @object.total_pages,
    :current_page =>  @object.current_page,
  }
end

returns

[
  { }
  { }
  { }
  { }
  { }
  { }
  { }
]

Though, it works fine with sinatra/rails

The next release of Grape has cleaner support for other formatters. I made a pull request into grape/rabl using the new syntax here: ruby-grape/grape-rabl#6.

This is what the user has to do:

formatter :json, Grape::Formatter::Rabl

Hope to see a lot more formatters our there!
