Allows ActiveRecord models to be specified as featured by updating a featured_at datetime (or timestamp) field on the model.
Also provides named scopes for featured and unfeatured finds.
Requires Rails > 2.1.0
Add a featured_at datetime field to any model that you want to be featured.
# Add the column
./script/generate migration AddFeaturedAtToPost featured_at:datetime
rake db:migrate
class Post < ActiveRecord::Base
acts_as_featured
end
Post.featured
# SELECT * FROM posts WHERE posts.featured_at IS NOT NULL
Post.unfeatured
# SELECT * FROM posts WHERE posts.featured_at IS NULL
@post.feature!
# UPDATE posts SET featured_at = '2008-07-08 15:58:34' WHERE id = 1
@post.unfeature!
# UPDATE posts SET featured_at = NULL WHERE id = 1
@post.featured?
# Return true if the post is featured, false if not
