Code Completion for Ruby on Rails


Is there no code completion for the Ruby on Rails environment? Trying to decide if C9 is a viable alternative to RubyMine by JetBrains. I come from a .NET MVC and iOS background where the IDEs are luxurious. Working in C9 editor seems to be comparable to a text editor.


Right now, Cloud9 supports code completion for Javascript/Node. Python code completion is experimental. Ruby on Rails is currently not supported.
