Hi there! I study Ruby on Rails and met a problem. I placed a class definition code for class which is NOT a Model into separate file, assume MyToolClass.rb Then I started working on controller code and required ‘MyToolClass’ While working on controller code I also corrected some code in MyToolClass.rb, but it seemed, that changes in MyTooolClass.rb were ignored by Rails until I had restarted Mongrel. Q#1: Please write to me how can I tell Rails to reread source files those were changed after last use. Q#:2 Where to place files like MyToolclass.rb, which are nither Model, nor Controller? Thank you for your attention. ---

If you’re not following naming conventions, then do as Fred suggests 🙂 Jeff [www.purpleworkshops.com](http://www.purpleworkshops.com) ---

I put each my class into it’s own file in app’s lib directory following naming conventions and Voila! After that every change in these files are incorporated immediately without require or require\_dependency calls. That’s great!
