undefined method `page' for # Kaminari::PaginatableArray

Question

I have been using Kaminari since a while. I use to paginate generic arrays using the following line.

Kaminari.paginate_array([1,2,3]).page(1).per(1)

That use to work before but I noticed that since yesterday this show the error

 undefined method `page' for #<Kaminari::PaginatableArray:0x007f8e5d10fde0>

However calling page on ActiveRecord relation is working fine. something like this is working

User.page(1).per(1)

Answer 1

Turned out to be that my colleague has added a configuration file for Kaminari and changed this page function with this line.

config.page_method_name = :kaminari_page

So instead of using Kaminari.paginate_array([1,2,3]).page(1).per(1) I should now use

Kaminari.paginate_array([1,2,3]).kaminari_page(1).per(1)
