Creating presenters with Resubject

Resubject is a (yet another) presenter gem based on Ruby's SimpleDelegator class. You don't need to explicitly expose any methods in your presenter, and only define those that require customization:

Example:

class Post < Struct.new(:title, :comments)
end

class PostPresenter < Resubject::Presenter
 # create comments method with 
 # instances of CommentPresenter
 presents :comments

 def title
 title.uppercase
 end
end

Then you can use:

PostPresenter.new(post).title
# => OMG!

PostPresenter.new(post).comments
# => [<CommentPresenter>, ...]

Rails

If you are using Rails, it automatically include some helpers for you:

class BoxesController < ActionController::Base
 def index
 @boxes = present Boxes.all
 end
end

And in your views:

<%= present(@box).contents %>
