Pagination
How this page is built
the gem renders it — this is all you write
The gem doesn't paginate on its own (no surprise row limits). You paginate in your controller with your own gem — here kaminari — and because a kaminari-paginated relation carries its page state, crud_collection notices and renders the footer pager automatically. The pager's ?page= composes with the gem's own filter/sort params (120 seeded books, 8 per page).
app/controllers/books_controller.rb
@query = CrudComponents::Query.new(Book, params, fieldset: :index, ability: current_ability)
@books = @query.apply(Book.all).page(params[:page]).per(8) # kaminari
app/views/pagination/index.html.erb
<%= crud_collection @books, query: @query %> <%# the footer pager renders itself %>
