Activeadmin Poro Decorator

Alternative for draper, if you need decorators at ActiveAdmin (and Rails). Active Admin uses the Draper gem for decorators, but sometimes you don't need that. For reasons you could read this article:

See discussion of PORO with Active Admin authors here.


Add this line to your application's Gemfile:

gem 'activeadmin-poro-decorator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activeadmin-poro-decorator

Then run rake-task to copy config file:

$ rake config:copy

Finally, rename activeadmin-poro-decorator.yml.sample to activeadmin-poro-decorator.yml:

$ mv config/activeadmin-poro-decorator.yml.example config/activeadmin-poro-decorator.yml


# app/admin/post.rb
ActiveAdmin.register Post do
  decorate_with PostDecorator

  permit_params :title

  index do
    column :id
    column :title
    column :hello       #delegated
    column :link_title  #delegated

# app/presenters/post_decorator.rb
class PostDecorator < DelegateClass(Post)
  include ActiveadminPoroDecorator

  def hello
    "Hello, #{title}"

  def link_title
    helpers.link_to(id, url_helpers.admin_post_path(self))
