What is the best file upload/attachment plugin rails?

Question

What are the pros and cons between PaperClip and Attachment_fu ?

Are there any other plugins that would you recommend ?

Is possible to support multiple file uploads and progress feedback on upload using these plugins and Passenger + Apache

Answer 1

I'm a huge fan of Paperclip because it doesn't require RMagick, it's very easy to set it up to post through to Amazon S3 and declaring everything in the models (validations, etc) keeps things clean.

With respect to multiple file uploads and progress feedback, both are possible with both Paperclip and Attachment_fu, but both typically require some elbow grease with iframes and Apache to get working.

A nice alternative is to use swf_upload (if you are ok with Flash) along with Paperclip to get both multiple uploads and progress bars in one step.

Answer 2

Paperclip is very good, otherwise there's a recent solution combining SWFUpload with a custom Rack Middleware here
