# Decorators
Active Admin supports the use of decorators for resources. Resources will be
be decorated for the index and show blocks. The [draper](http://github.com/jcasimir/draper)
gem is recommended but not required (more on requirements below).
## Configuration
ActiveAdmin.register Post do
decorate_with PostDecorator
end
## Example Usage
This example uses [draper](http://github.com/jcasimir/draper).
# Gemfile
gem 'draper'
Assuming a post and a post decorator
class Post < ActiveRecord::Base; end
class PostDecorator < ApplicationDecorator
decorates :post
def image
h.image_tag model.image_url
end
end
Then the following is possible
ActiveAdmin.register Post do
decorate_with PostDecorator
index do
column(:title)
column(:image)
end
show do
attributes_table do
row(:title)
row(:image)
end
end
end
