Re: #1--you want to call either .to_i or .to_f on your now-string variables. The former converts to integer, the latter to a floating point number.
Also (and read this next bit w/the voice of the Simpson's Comic Book Guy in your head) there is no compiler--ruby is an interpreted language, it has an interpreter. ;-) -Roy P.S. That calculation you show looks like it would be better put in a model. -----Original Message----- From: rubyonrails-talk@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Phil Sent: Monday, September 08, 2008 9:40 AM To: Ruby on Rails: Talk Subject: [Rails] Amateur Programmer Hi, I have two questions: 1) How do you cast in RoR2? I have this: <% .... total = 0; (@person.quizzes).each { |a| puts total+=a } .... %> <%= total %> However, the compiler treats a as a string. I want it to be an number. Help? 2) How do I make this (http://github.com/activefx/ restful_authentication_tutorial/tree/master/) work in an application?
