I''m new to Ruby and Rails, and I''m not sure which is most responsible for my confusion here. :) I have a minor legacy db issue: something that should be an int(3) is a char(3) instead. And it needs to be increased by an offset number to match other records. In PHP, this was fairly trivial, but in RoR, I''m having a frustrating time with it. First, I tried this: def project_no @project_num = project_num.to_i + 10 someMethod (project_num) end But this doesn''t work. someMethod always thinks that project_num is just 10 (ie, to_i converted project_num to 0). So I tried this: def project_no score = project_num.to_i score += 10 @project_num = score someMethod = project_num end And that worked. But it''s slightly ugly. And I, ultimately, I really want something more like: def update_project_no @project_num + 10 end def project_no @update_project_no someMethod (project_num) end Can anybody straighten me out here? I''d be much obliged. -- joshua --- Geek out: www.thewehners.net/joshua/

You can help to narrow down the issue by doing that same require_gem call in irb (or a small script): require ''rubygems'' require_gem ''activerecord'' #for example to see if it fails in this mode. -- Chad Fowler http://chadfowler.com http://rubycentral.org http://rubygarden.org http://rubygems.rubyforge.org (over 100,000 gems served!)

Just redefine the accessor for project_num:
class Project < ActiveRecord::Base
~ def project_num
~ read_attribute("project_num").to_i
~ end
~ def project_num=(number)
~ write_attribute("length", number.to_s)
~ end
end

> Tim, what''s on this line:> > /srv/www/mycms/public/../config/environment.rb:42 Thanks for trying to help. On line 42 of environment.rb I have require_gem ''syntax'' which made me realize this gem was not installed for some reason and throwing an error. When a did a gem install syntax, I can now run the test script in irb. Cool... Unfortunately, now I''m getting a "SyntaxError in <controller not set>#<action not set>" error but at least I''m making progress.
