I installed a gem called: Contacts

From the console this works:

Contacts.new(:hotmail, “asdasd”, “asdasd”)"

But from the controller I get “uninitialized constant  
FriendFindersController::Contacts” when I try to load the page? Same  
thing  
if I put the call to Contacts in the model.

Anyone have any ideas?

Have you required the gem in your environment.rb?

Probably, you just need to require the gem in your environment.rb file  
and restart your server.
