Decoro

Decorators for Rails. Use only certain code for views? Decorators are the spot to put it!

Add this line to your application's Gemfile:

gem 'decoro'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install decoro

Say you have a need to transform products to an options array (for use in a select):

class ProductsDecorator < ApplicationDecorator
  def options_for_select
    model.map { |p| [p.display_name, p.id] }
  end
end

Then in your view:

- decorate(@products) do |products|
  = f.association :product, collection: products.options_for_select

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
