IM new to Ruby and RoR. I have very less prior experience with web techs. I know how web works and worked with pre coded php code (edited em)... and ran websites with template scripts and wordpress cms.
But never built em on my own.
Now I wanna learn a web framework. and RoR seems to be the most popular one. everyone's talking about it.
So I dont know much php, java script or Ajax.
Im learning Ruby language now.
SO to setup successful web apps with RoR do I need any of above technologies??
