Nice additions to Rails’ Ajax support

Ruby on Rails 0.11.1 features some improvements to the Ajax support added in 0.11.

The Ajax wave is sweeping across Rails. In this release, we’ve added a :position option to both link_to_remote and form_remote_tag that can be set to either :before, :top, :bottom, or :after. These options make it possible to add new DOM elements to existing lists without replacing the whole list. When working on big lists that are in a fixed order anyway, there’s a considerable speed increase to be had.

Nice! In my earlier post mentioning Ajax in Rails, I talked about Nevow’s LivePage coming first. While that is true, and while it is also true (as far as I know) that Rails doesn’t support LivePage’s ability to call from server-to-client at will, it is cool to see new ease-of-use API ideas coming up.
