Pageable interface to paginate with Kaminari in GraphQL Ruby

pageable_type.rb

module Types
  module PageableType
    include Types::Base::Interface
    field :current_page, Integer, null: true
    field :previous_page, Integer, null: true, method: :prev_page
    field :next_page, Integer, null: true
    field :total_pages, Integer, null: true
    field :total_items, Integer, null: true, method: :total_count
    field :size, Integer, null: true, method: :count
    field :first_page, Boolean, null: true, method: :first_page?
    field :last_page, Boolean, null: true, method: :last_page?
  end
end

Thanks! Really appreciate you mentioning this! I ended up coming up with my own solution (using a proxy class to expose the kaminari AR object methods as GQL fields)

But maybe this will help someone else in the future who finds this.

Hi guys, sorry I didn't notice the notification.

@Shaglock totally nailed the solution, and the interface is indeed meant to be compatible with Kaminari-like pagination libraries.
Implementing items in a BaseCollection that extends BaseObject is a wonderful idea to keep code DRY.
