Pagination

Table (gem footer pager) Cards (kaminari default pager)
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 %>
