Heroku File Storage

Solution 1:

I would recommend you to check heroku add-on solution which is https://addons.heroku.com/cloudinary. You will get 500MB for free and easy heroku integration.

For RoR app you can check: https://devcenter.heroku.com/articles/cloudinary#using-with-ruby-on-rails

There is also documentation for Nodejs and Django.

Solution 2:

See this blog post

In your model.

has_attached_file :picture, 
                   :styles => {:large => "275x450>"},
                   :storage => :s3, 
                   :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
                   :path => "appname/:attachment/:style/:id.:extension"

In s3.yml in your config dir:

    development:
      bucket: bucketname
      access_key_id: key
      secret_access_key: key

    production:
      bucket: bucketname
      access_key_id: key
      secret_access_key: key

Then go signup for a bucket at Amazon S3: http://aws.amazon.com/s3/
