Rails: How to bind large table to a list

Question

I am new to rails, most of my experience is with desktop (Windows) GUI.

In Windows it is possible to bind s a listview to a database table. the GUI component hold a only the visible rows of the large table.

if the user scroll up/down to rows not in view, the control do a "behind the scenes" query in database to get the new rows to be displayed.

That allows the GUI to map arbitrary large tables with constance memory usage.

I am sure there must be a similar technique for rails, most likely with the aid of JQuery but I failed to find it.

I assume the terminology is different is the web world

I would recommend a combination of the will_paginate gem, AJAX, and some javascript framework (jQuery, prototype, AngularJS, etc.). You can use will_paginate to render the first page, and then as the user scrolls down, monitor the scroll progress and load more records. Here's a link to get you started.
