I’ve just upgraded rails to 1.2 and now everything breaks when accessing  
pages that use tzinfo.

I get the following errors:

uninitialized constant FriendController::Timezone  
c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.1/lib/active\_support/dependencies.rb:477:in  
`const_missing' #{RAILS_ROOT}/app/controllers/friend_controller.rb:22:in`index’

Can someone please tell me how to “require” tzinfo so it can be used in  
any of my controllers?

Could this be something to do with this:

We’ve fixed a bug that allowed libraries from Ruby’s standard library to  
be auto-loaded on reference. Before, if you merely reference the  
Pathname constant, we’d autoload pathname.rb. No more, you’ll need to  
manually require ‘pathname’ now.

(from  
[http://weblog.rubyonrails.org/2006/11/23/rails-1-2-release-candidate-1](http://weblog.rubyonrails.org/2006/11/23/rails-1-2-release-candidate-1))

If so you’ll have to stick require ‘tzinfo’ at the top of files that use  
it.

thanks. to get it working I had to:  
#at the top of config/environment.rb  
require ‘tzinfo’

AND

#at the top of my controller  
include TZInfo

Now if only I can get the search\_generator working now…it simply  
refuses to load the Search module. IF anyones got a solution or willing  
to help I’d be happy to throw a few $$ at them for their time.

require ‘tzinfo’ in your config/environment.rb file.
