问题
Only mentions Rails 3 in the GitHub documentation - does anyone know if it's compatible with Rails 4?
I ask because it looks like it's been updated to handle Ruby 2.1.0
回答1:
According to the travis build, tests pass with active record 4.
回答2:
Indeed, it works. We've been using it in one of our recent projects. You can also look at travis.yml file in the repo. It was tested to work with ActiveRecord 4.0.
回答3:
Yes it's compatible with Rails 4, but you need to add :parent_id to permit params in your controller.
