Hi RoR Developers, I’m quite new to MVC model , I have some pretty basic questions that I hope some of you can answer. I have two controllers and one view page like below, I want to call variables from report\_controller in view page. in fact view page for sheet\_controller and I m wondering if there is a way to reach that variables from report\_controller in the view page of sheet. another question is also quite same. how can I call the variable from report\_controller, in sheet\_controller. there is a “project” folder in controller 2 controller(Sheet\_controller, report\_controller) and 1 views - for sheet\_controller thanks ---

I hope this gave you a birds eye view. May I suggest you pick up a good RoR book to get you more familiar with MVC. ilan ---
