File column plugin

Plugin details

This library makes handling of uploaded files in Ruby on Rails as easy as it should be. It helps you to not repeat yourself and write the same file handling code all over the place while providing you with nice features like keeping uploads during form redisplays, nice looking URLs for your uploaded files and easy integration with RMagick to resize uploaded images and create thumb-nails. Files are stored in the filesystem and the filename in the database.

                         "portfolio" => "190x400",
                         :square => {:crop => "1:1", :size => "50x50", :name => "square"} }
        }
