Speech bubble icons have become synonymous with comments. When creating yet another one for a standard comment link, it occurred to me that there might be a way to make the icon without ever opening up an image editor. It could all be done with CSS

Pretty print your Ruby objects with style -- in full color and with proper indentation

File upload solution that supports form roundtrips when a validation fails.

No images whatsoever.

CSS Level 3 brings with it some incredibly powerful styling features. Rounded corners, soft drop shadows, gradient fills, and so on. These are the kinds of elements our designer friends love to use because they make for attractive sites, but are difficult and time-consuming to implement, involving complex sprite images, extra non-semantic markup, large JavaScript libraries, and other lovely hacks.

Just assign the existing attachment to another record:

new_photo = Photo.new
new_photo.image = old_photo.image

Paperclip will duplicate the file when saving.

To use this in forms, pimp your attachment container like this:

class Photo < ActiveRecord::Base
  has_attached_file :image
  
  attr_accessor :copy_of

  def image_url
    if copy_of
      copy_of.url
    else
      image.url
    end
  end
end

And in the controller do:

new_photo = Photo.new(:copy_of => old_photo)

Insert into ~/.bashrc and reload afterwards: source ~/.bashrc
