Hi, David H.H. announced recently that jquery is going to be the default in Rails 3.1, and that Prototype helpers / RJS are going into a gem. What does that mean for the future? Should we progressively forget about things like javascript helpers, RJS, and all these fun parts of rails? And start coding with jquery/json in mind? I''m not against that at all, but I have to admit I find RJS

This release packs in lots of cool new features, a few changes to old ones and some performance enhancements. Now you can write your behaviours in Ruby, attach behaviours directly to elements using content_tag and apply behaviours to elements without HTML IDs.

Hi all, The "form_for" helper and its friends "text_field_for" etc generate form fields with names like "forum[title]", i.e. using square brackets to denote attributes on model objects.

What if...you could produce accessible, unobtrusive javascript, using Rails built-in javascript/prototype helpers, with just one extra line of code in your layout, a plugin, and one small enhancement to the helpers.
