Overview

The GridFS store uses MongoDB's GridStore file storage system to store files

When you already have a Mongo connection object (for example through Mongoid) you can also reuse this connection:

CarrierWave.configure do |config|
  config.storage = :grid_fs
  config.grid_fs_access_url = "/system/uploads"
end

In the above example your documents url will look like:

 http://your-app.com/system/uploads/:document-identifier-here
