In my project i am using paper-clip and deployed to heroku, heroku not allows the file storage but to use aws normally, i don’t want to spend money so i can use drop box storage which will gives 2gb free storage space.
So i am using paper-clip with drop box with library papercklip-dropbox gem, steps to follow are given below.
  1. Include  gem “paperclip-dropbox” in your gem file
  2. Run the command $bundel install 
  3. Create drop box api app in https://www.dropbox.com/developers/apps   and give read write permissions it gives you the App key and App secret  which will used in further configeration
  4. Generate the other required details using available details, run the rake task to generate other details “$rake dropbox:authorize APP_KEY=your_app_key APP_SECRET=your_app_secret ACCESS_TYPE=your_access_typ “, this command will generate the access_token, access_token_secret, user_id
  5. Create dropbox_config.yml  file in config folder and place all keys got in previous steps 
    app_key:  YOUR_APP_KEY
    app_secret: YOUR_APP_SECRET
    access_token: YOUR_ACCESS_TOKEN
    access_token_secret:  YOUR_ACCESS_TOKEN_SECRET
    user_id:  YOUR_USER_ID
    access_type: “app_folder”
  6.  Now relace paper clip code with new code for attachment, like User profile picture
    #added for paperclip-dropbox gem
    has_attached_file :picture,
    :storage => :dropbox,
    :dropbox_credentials => “#{Rails.root}/config/dropbox_c
    onfig.yml”,
    :styles => { :medium => “300×300” , :thumb => “100×100>”},
    :dropbox_options => {
    :path => proc { |style| “#{Rails.env}/#{style}/#{id}_#{picture.original_filename}”},       :unique_filename => true
    }
  7. Deploy your code  in heroku you can, you can see all files or images uploaded as profile pictures will store in your drop box.
Enjoy the drop box free usage in cloud
