Question

I’m using the gem called ‘acts_as_follower’ and ‘kaminari’.
If I put .page(params[:page]).per(10) in the end of the line that fetches records with acts_as_follower, it gives back error. So I removed it.
How can I use pagination with this gem ‘acts_as_follower’?

Error

NoMethodError in UsersController#following
undefined method `page' for #<Array:0x00000018593928>

current users_controller.rb Fetching part

@users = User.find_by_username(params[:id]).all_following(order: 'updated_at DESC')

Answer 1

Since the all_following(order: 'updated_at DESC') method returns an array object, you’d need to use Kaminari’s PaginatableArray.

Add the code below to your controller:

@users = Kaminari.paginate_array(@users).page(params[:page]).per(10)

Then the pagination should work as you’d expect.
