Setting Amazon S3 for Paperclip and Heroku

The latest Paperclip release 5.1.0 has changed a little bit the way to set it up with Amazon S3 service (Amazon Simple Storage Service). Moreover, after googling a lot here and there, we could see many solutions and settings, some of them being outdated, some - often different and did not work well. So I decided to summarize in one replace all the steps needed to set up your Rails application deployed on Heroku and be able to use it with Paperclip 5 and Amazon S3 service.

In case you don't know, Heroku does not allow your Rails application to write and offers read only access. What means that you can't use Paperclip and save your files to Heroku's file system.

So you will have to find a way to upload/store/read your files. As stated in Paperclip documentation, Paperclip ships with 3 storage adapters:

# Enables PostgreSQL interval datatype support (as ActiveSupport::Duration) in Ruby on Rails 4.1.
# Based on https://gist.github.com/clarkdave/6529610

require 'active_support/duration'

# add a native DB type of :interval
ActiveRecord::ConnectionAdapters::PostgreSQLAdapter::NATIVE_DATABASE_TYPES[:interval] = { name: 'interval' }

# add the interval type to the simplified_type list. because this method is a case statement
# we can't inject anything into it, so we create an alias around it so calls to it will call

class User < ActiveRecord::Base
  # gradual engagement is needed, to allow admin creation of users
  # users should create authorization data only when they need to
  # access some system feature that requires authentication
  # So ... our gradual engagement scheme for authlogic:
  # 1. admin creates user, setting only name and phone number (required)
  #    admin may set email address (optional)
  # 2. user is sent email invitation with link to activate their account
  #    admin can re-send email at user's request
  # 3. user sets login and password/password_confirmation using activation form
