Question

I am attempting to paginate a shuffled ActiveRecord query. The syntax for doing this using the Kaminari gem is:

@users = Kaminari.paginate_array(User.all.shuffle).page(params[:page]).per(20)

The issue with this is that User.all is re-shuffled on each pagination request, causing duplicate records to be called. Is there any way to prevent this kind of duplication?

Answer 1

You need to pass seed for rand between queries

params[:seed] ||= Random.new_seed
srand params[:seed].to_i
@users = Kaminari.paginate_array(User.all.shuffle).page(params[:page]).per(20)

And in view add params[:seed] to all kaminari links to pages
