Undefined method `acts_as_tree'

Question

I am upgrading a project from rails 2 to 4 but cannot find what is the equivalent gem for "acts_as_tree" for rails 4. I saw threads saying "acts_as_tree" is already deprecated, so am looking for another way to use this method in Rails 4. Thank you!

Answer 1

acts_as_tree is now a gem. If you want to use it - add it to your Gemfile

Here is the acts_as_tree project on github: https://github.com/amerine/acts_as_tree
