Expected script/…/config/…/app/controllers/backups\_controller.rb to  
define BackupsController

The backups\_controller.rb script should define BackupsController class.

I thought so, but this is my app/controller/backups\_controller.rb

class BackupsController \< ApplicationController  
before\_filter :check\_authentication

Page\_Size = 15

def index  
list  
render :action =\> ‘list’  
end

# GETs should be safe (see

[URIs, Addressability, and the use of HTTP GET and POST](http://www.w3.org/2001/tag/doc/whenToUseGet.html))  
verify :method =\> :post, :only =\> [:destroy, :create, :update],  
:redirect\_to =\> { :action =\> :list }

def list  
@backup\_pages, @backups = paginate :backups, :order =\> “bkcode  
DESC”, :per\_page =\> Page\_Size  
end

def show  
@backup = Backup.find

bla, bla, bla…

end

Before I got this error, I was using Edge-Rails, then I updated to  
Rails 1.2.2 then nothing works now. Any tips?

I’m sorry , I’ve updated gems and server go up ok, but I still have  
the problem with the controller… it says it isn’t defined but  
the file it’s in… Something new in 1.2.2 that I have to have in  
count?

I thought I forgot to update the project with rake rails:update  
(in /home/eyp/Desarrollo/ruby/repository/rtapelib)  
install -c -m 0755 /usr/lib/ruby/gems/1.8/gems/rails-1.2.2/lib/  
tasks/…/…/bin/process/inspector script/process/inspector

But when I run the server now I get this error:

ruby script/server

./script/…/config/boot.rb:29: undefined method `gem' for main:Object (NoMethodError) from script/server:2:in`require’  
from script/server:2

What’s going on now?
