ActsAsPhotoable

This acts_as_photoable provides the capabilities for models to have photos.
It's based on use the paperclip plugin to handle the photo upload.

== Usage

Generate and apply the migration:

ruby script/generate acts_as_photoable_migration rake db:migrate

class Post < ActiveRecord::Base
acts_as_photoable

end

class Photo < ActiveRecord::Base  #this need you create,  not generate
  belongs_to :photoable, :polymorphic => true

  has_attached_file :photo,
      :styles => {
        :thumb=> "40x40#",
        :small  => "176x100>",
        :main  => "706x403>" }

  Content_Types  = ['image/jpeg', 'image/pjpeg', 'image/gif', 
        'image/png', 'image/x-png', 'image/jpg']
  validates_attachment_content_type :photo, :content_type => Content_Types

end  

#-------just sample code in controller!!
def create
@post = Post.new(params[:post])       

respond_to do |format|
  if @post.save && @musician.save_with_photos(params[:photos])
    format.html { redirect_to @post }
  else
    format.html { render :action => "new" }
  end
end

end

--------the save_with_photos will handle the save logic for photos

it require the params[:photos] like "photos"=>[#, #]

maybe you would like to use rake aap:cp_photos_view to generate the view file for upload photos to app/views/shared, then <%= render :partial => "shared/upload_photo" %> to use it in the view. it use a little jquery to work to me, you should feel free to change it.
