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!

  • [`acts_as_tree`](https://github.com/amerine/acts_as_tree) doesn't appear to be deprecated. – mu is too short Feb 09 '17 at 03:15
  • I already installed using 'gem install acts_as_tree' and then bundle install. But it still gives me the same error 'undefined method `acts_as_tree' – skyranch Feb 09 '17 at 03:54

    `gem install acts_as_tree and then bundle install.` because this isn't how you install a gem using bundler... add it to your `Gemfile` then run bundle install. After doing so, it should be listed in `Gemfile.lock` – Taryn East Feb 09 '17 at 04:18

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
