acts_as_restful_list¶ ↑

It’s just like acts_as_list, but instead of having to clutter your code with non-standard method calls like insert_at, acts_as_restful_list makes managing lists simple. You update the position attribute just like you would update anything else and the rest is taken care of for you.

• Automatically update your list’s order through standard REST methods

• Support for Rails Optimistic Locking

#environment.rb
config.gem 'acts_as_restful_list'

# in Terminal
rake gems:install

class Item < ActiveRecord::Base
  belongs_to :parent
  acts_as_restful_list :scope => :parent
end

item = Item.create
item.position # 1

item2 = Item.create
item.position # 2

item3 = Item.create
item.position # 3

item.destroy
item2.position # 1
item3.position # 2

item3.position = 1
item3.save
item3.position # 1
item2.position # 2

different_parent = Item.create(:parent_id => 1)
different_parent.position # 1

And that’s that.

• Fork the project.

• Make your feature addition or bug fix.

• Add specs 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.
