Presentable

Making presenters easy and fun!

Setup for Rails

Update config/environment.rb

config.load_paths += %W( #{RAILS_ROOT}/app/presenters )

Create a presenter class

class PostPresenter < Presenter
  def title
    "#{original_title} - <span class='date'>#{created_at.strftime('%B %d')}</span>" # reference old values by prefixing them with original_
  end
end

Call present on your instance

@post = Post.find(params[:id]).presenter

Use presenter methods in your view

<h2><%= @post.title %></h2>
<p>@post.body</p>
