This plugin when used in conjunction with the paperclip file attachment plugin allows you to attach more than one file to the model.

PaperclipPolymorph

This plugin allows users of the Paperclip plugin to easily share attached files between
multiple models. Essentially, polymorphic paperclip transparently saves the attached files
into a separate asset’s table and associates the the model to the asset through a polymorphic
attachings table.

The Paperclip Plugin must also be installed for PolyMorphicPaperclip to work.

Example

class PhotoEssay < ActiveRecord::Base
  acts_as_polymorphic_paperclip
end

You can also add a counter_cache to your model if you wish.

class Essay < ActiveRecord::Base

  acts_as_polymorphic_paperclip :counter_cache => true

end

essay.assets.attach(asset)

essay.assets.asset.detach -or- @essay.assets.detach(asset)

Helper methods

There is one helper method so far used to determine if the asset can be displayed in a browser

@essay.assets.first.browser_safe? # => returns true or false
