Storing Images in Postgres DB Store RefineryCMS with Dragonfly

My application is a refineryCMS which is been hosted on the heroku server . I need to store the images on the postgres DB store. I got one gem dragonfly-activerecord , but not able to keep it on database . I tried:

Configure Dragonfly itself (in config/initializers/dragonfly.rb, typically):

require 'dragonfly-activerecord/store'

Dragonfly.app.configure do
 # ... your existing configuration here
 datastore Dragonfly::ActiveRecord::Store.new

We need to integrate this gem into refineryCMS.. If we can store images in database for cms that will be great help for host like heroku.

Here is a solution along with the dragonfly-activerecord fork . Just go to config/initializers/refinery/images.rb Here is a code to do it. First follow dragonfly-activerecord fork steps

In Gemfile:

gem 'dragonfly-activerecord' , git: "git://github.com/arpit-clarion/dragonfly-activerecord.git" and

bundle

rails generate migration add_dragonfly_storage

In the migration file add this code

require 'dragonfly-activerecord/migration'

class AddDragonflyStorage < ActiveRecord::Migration
  include Dragonfly::ActiveRecord::Migration
end

Run rake db:migrate and add this code:

config/initializers/refinery/images.rb
# encoding: utf-8
require 'dragonfly-activerecord/store'
Refinery::Images.configure do |config|
  #...... Your configuration ....
  config.custom_backend_class = 'Dragonfly::ActiveRecord::Store'
  config.custom_backend_opts = {}
  #...... Your configuration ....
end

This will change the whole system folder structure set into database. No need to any buckets .

Keep in mind that this system is for those applications which has less images to store as it generates big chunks in db and it converts images on request time.
