Pros

Uses a separate Uploader class which can share behavior with more than one model

https://gist.github.com/1005026

Uploaders can use the Fog cloud abstraction library

• Amazon S3
• Rackspace CloudFiles
• Google Storage for Developers
• Local Storage

Uploaders are designed well for easy customization

https://github.com/highgroove/discovery-port/blob/master/app/uploaders/attachment_uploader.rb#L13-19

Local Storage can be used in development to avoid the overhead of the wire

https://github.com/highgroove/discovery-port/blob/master/config/initializers/carrierwave.rb#L3

Processing can be disabled in test to avoid the overhead of processing (resizing, etc.)

Cons

Does some kind of tricky black magic on the ActiveRecord field

Workaround - just store it at the moment we get it from the browser

add_column :attachments, :original_filename,  :string
add_column :attachments, :content_type,       :string
