Answer 1

You might want to put the :action => "bycategory" and :id => 'All' in a hash as

<%= link_to 'All', { :action => "bycategory", :id => 'All' }, :remote => true %>

This will generate the proper html attribute i.e. data-remote="true" otherwise it will simply treat everything following as an http request attribute. Your code will generate -

<a href="/bycategory?id=All&amp;remote=true">All</a>

whereas using the hash will generate something similar to

<a data-remote="true" href="/bycategory/All">All</a>

I had the same problem with Rails 3.1.3 and I cured it with rake assets:precompile,but ensure you have in application.js "//= require jquery_ujs" instead of "//= require jquery",this was the main problem and I spent at least 12 hours before I decided do it this way!Terrible!
