kaminari undefined method `page'

Question

I've been trying to play around with the Kaminari gem for pagination, but am running into problems.

I've got a simple starter project with a simple model:

class Position < ActiveRecord::Base
  validates_presence_of :name
end

I'm running with ruby 1.9.2 and rails 3.0.5 on Ubuntu 10.04. I've installed kaminari (0.10.4).

From what I understand, I should be able to execute Position.order("name").page(1), but when I do so, I get the following:

ruby-1.9.2-p0 > Position.order("name").page(1)
NoMethodError: undefined method `page' for #<ActiveRecord::Relation:0xaacab34>
    from /home/bob/.rvm/gems/ruby-1.9.2-p0@talentskout/gems/activerecord-3.0.5/lib/active_record/relation.rb:371:in `method_missing'
    from (irb):2
    from /home/bob/.rvm/gems/ruby-1.9.2-p0@talentskout/gems/railties-3.0.5/lib/rails/commands/console.rb:44:in `start'
    from /home/bob/.rvm/gems/ruby-1.9.2-p0@talentskout/gems/railties-3.0.5/lib/rails/commands/console.rb:8:in `start'
    from /home/bob/.rvm/gems/ruby-1.9.2-p0@talentskout/gems/railties-3.0.5/lib/rails/commands.rb:23:in `<top (required)>'
    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

This seems about as simple a scenario as I can get. Any ideas would be greatly appreciated.

Thanks.

Rails noob here: had precisely the same issue but for a different reason - I found I had to restart the server after adding the kaminari gem and running bundle install. Just mentioning it in case someone else has the same problem!
