Fix undefined method `per' error on Will_Paginate and ActiveAdmin

To get Will_Paginate and ActiveAdmin to play nice and avoid this error:

undefined method `per' for #<ActiveRecord::Relation:0x000000076c9b28>

In your config/initializers, add this:

# config/initializers/kaminari.rb
Kaminari.configure do |config|
  config.page_method_name = :per_page_kaminari
end

Just add method per(25) after each "perpagekaminari" call and it should work.
I guess kaminari has some troubles with initialization. After you will added method "per", reload page and remove this "per" method Kaminari started woks fine.

Kaminari.configure do |config|
....
end
