Ruby on Rails with emacs24

[Markus Grunwald <news.the-grue@spamgourmet.com>]

Hello,

I'm an emacs on linux user and just starting to learn ruby on rails. I 
was quite surprised that emacs support for RoR seems to be … well … 
suboptimal ;)

There's a rails-mode, but that's it. I've found tons of information about 
nxhtml, rinari, mumamo, rails, emacs-rails and whatnot. I read lots of 
posts on www.emacswiki.org. But all of the sources that I got were from 
stone age and didn't either match the current ruby nor the current emacs 
version :( Some things worked fine (flymake for example, or a few 
shortcuts from emacs-rails) others were completely messed up like mumamo 
which auto-inserts syntax errors and spams my *Messages* buffer.

Could someone please point me to current ruby on rails support on emacs? 
Or is there only the rails-mode from emacs24?

Thank you very much,
Markus
