Simple form

Add the gem to your GemFile
gem 'simple_form'

run bundle for downloading the Gem
bundle install


Deploy the gem:

rails g simple_form:install

This creates some files under your project

      create  config/initializers/simple_form.rb       exist  config/locales      create  config/locales/simple_form.en.yml      create  lib/templates/erb/scaffold/_form.html.erb

Following the previous sample of books, these are the only lines you need for your _from.html.erb under app/views/books

<%= simple_form_for(@book) do |f| %>

    <%= f.input :name %><br />

    <%= f.association :status %><br />

    <%= f.button :submit %><br />

<% end %>

Notices that we use simple_form_for instead form_for and just one line for each component. simple, hun?
