In hanami guide https://hanamirb.org/guides/1.2/associations/has-many/#usage
when I use the method
@book = BookRepository.new.find_with_tickets(params[:id])
I got a message:
[deprecated] Relation#as will change behavior in 4.0. Use `map_to` instead

I do not know what should I instead use 'map_to'.
you should replace #as with #map_to, and it will work as usual.
