Unfortunately I cannot come close to recommending Joomla. Looking through the core code of the system is an exercise in frustration at best. While the code is not necessarily all super-bad the documentation is lacking in the extreme. I would recommend starting from scratch in Rails. That way you'll have control over every aspect of the design and function of the system and it will be you alone that is responsible for the quality of the code and the system overall...
