Ruby has attr_* for getters and setters:

Well, you’re not going to be doing this in Ruby, since HTTP is
stateless. Since you’re using AJAX, you might as well store your
entire resultset as JS, and fetch each page from your local
collection. That said, maybe you should look at Mislav will_paginate
(GitHub - mislav/will_paginate: Pagination library for Rails and other Ruby applications). Sure, you’ll hit the DB for
each page, but it’s simple to implement, it’s well tested and it
performs reasonably well.
