acts_as_taggable_on_steroidsのnamed_scope

  named_scope :tagged_with, lambda{|tags| find_options_for_find_tagged_with(tags) }

とこんな感じ.
 

class Reminder < ActiveRecord::Base
  acts_as_taggable
  named_scope :user, lambda{|user_id| {:conditions => ["#{table_name}.user_id = ?", user_id]} }
  named_scope :tagged_with, lambda{|tags| find_options_for_find_tagged_with(tags) }
end

こんな定義であれば,
 

Reminder.user(1).tagged_with("hoge")

という感じでできる.おお,何かかっこいい.
