If you're on a recent version of Rails, it would be best to replace
the 'active' method above with a named scope:
named_scope :active, :conditions => { :state => 'active' }
Then you can use User.active as a base to find only active users. Note
that the scope supports all the
various find methods, ie:
User.active.find(:all, :order => 'last_name', :limit => 5)
will work. See the docs at
http://api.rubyonrails.org/classes/ActiveRecord/NamedScope/ClassMethods.html#M002120

However, on looking at the classic_pagination docs, it may be a bit of
a hassle to create the paginator.
With the new will_paginate, your controller will only need:
def list
@users = User.active.paginate params[:page] || 1 # other options as
needed
end
You may want to consider upgrading...
