Acts As List¶ ↑

This acts_as extension provides the capabilities for sorting and reordering a number of objects in a list. The class that has this specified needs to have a position column defined as an integer on the mapped database table.

Install¶ ↑

Rails 3¶ ↑

Specify it in your Rails Gemfile:

gem "acts_as_list"

Then install it:

bundle install

Rails 2¶ ↑

Specify it in your Rails config:

config.gem “acts_as_list”, “~>0.1”

Then install it:

rake gems:install

Example¶ ↑

class TodoList < ActiveRecord::Base
  has_many :todo_items, :order => "position"
end

class TodoItem < ActiveRecord::Base
  belongs_to :todo_list
  acts_as_list :scope => :todo_list
end

todo_list.first.move_to_bottom
todo_list.last.move_higher

Note on Patches/Pull Requests¶ ↑

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don’t break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
