You have a number of choices:
1.
/lib/commentable.rb
module Commentable
def self.included(base)
base.has_many :subscriptions, :as => :subscribable
# and so on
end
end
/app/models/blog_post.rb
class BlogPost < AR::B
include Commentable
# rest of class definition
end
2.
/lib/commentable.rb
# as in 1, but after the end of the module (or in environment.rb):
class ActiveRecord::Base
def self.acts_as_commentable
include Commentable
end
end
/app/models/blog_post.rb
class BlogPost < AR::B
acts_as_commentable
end
3 (probably not recommended).
/config/environment.rb
class ActiveRecord::Base
def self.acts_as_commentable
has_many :subscriptions, ;as => :subscribable
# and the other has_manys
end
end
4. Write an acts_as plugin (but call it something else -- I think
acts_as_commentable is already taken as a plugin name).
Does that help?
Best,
