Rails - Jan 2005 - paging

So I want to display a result set on a page. But I only want 10 results 
on the page along with a link to the next set of 10 in the results. Is 
there a component for this in Rails? If not, how do people approach 
this problem in Rails?

Thanks,

Jamie

Dang if I didn''t find, read about, download and implement 
PaginationHelper between the time I posted and the time I read your 
reply. That helper rocks!

I have tried to use ActiveRecord as session storage mechanism by following the
instructions on

  http://wiki.rubyonrails.com/rails/show/HowtoChangeSessionOptions

Specifically I added the line

  ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.update(:database_manager
=> CGI::Session::ActiveRecordStore)

to environments/development.rb. On the first visit to a page, a session entry is
added to the database, but when I try to accesss
the session with the following code

	@session[''user''] =
User.find_first("name=''gast''") unless
@session[''user''])

I get an error: (works perfectly with pstore)

 IndexError in Rezept#index

string not matched

/app/controllers/rezept_controller.rb:282:in `auth_action''

So it seems as if some part of rails still thinks it should use pstore instead
of the database.

Is something wrong with my setup or is this a bug?

Stefan,

Please see http://dev.rubyonrails.org/ticket/430  There is something 
funky going on with ActiveRecordStore when using the development and 
test environments, though it seems to be working in the production 
environment.  My guess is that it has something to do with the 
auto-reloading in the dev/test environments, but I''m not sure just
where
it''s breaking down.

Scott,

thanks very much, it works in the production environment.

Could you please tell me how I can receive a notification when the ticket is
closed? Do I need a userid on the Trac system and if
so, how can I get one?
