Limesurvey alternative for Ruby on Rails?

Does an开发者_Go百科yone know of a full featured survey tool for rails? Like Limesurvey (PHP -unfortunately for my purposes.)? Tried to look on Ruby-toolbox, but it seems to be down.

have a look on GitHub?

I am working on an online survey/test framework. Limesurvey works but the code and database design does not fit for my purpose.
