RJS templates - newbie

I am trying to test drive RJS templates in Rails 1.2. Here is what I

create table categories (name varchar(255) );

rails RJSTest
cd RJSTest
rake update_javascripts
script/generate controller home index add
script/generate model category

Note: When I did a rake update_javascripts, I did not see any output.

I configured database.yml to talk to mysql.

Next I wrote controller/home_controller.rb:
class HomeController < ApplicationController

def index
	@categories = Category.find( :all )

def add
	@category = Category.new

	if request.post?
		@category = Category.create( params[:category] )


Then I wrote views/home/index.rhtml:
<%= form_remote_tag :url => { :action => ‘add’ } %>

Category: <%= text_field 'category', 'name' %>
<%= submit_tag 'Add' %>

<%= end_form_tag %>

    <% @categories.each do |category| -%>
  • <%= category.name %>
  • <% end -%>

Then I wrote views/home/add.rjs:
if @category && @category.errors.empty?
li = content_tag( ‘li’, @category.name )
page.insert_html :bottom, ‘categories’, li
page.visual_effect :highlight, ‘categories’, :duration => 3

Now when I point my browser to http://localhost/home/index.rhtml, I see
my form and i can submit a category name. The add action in the
controller then goes to add.rhtml instead of add.rjs. Evidentally, I am
missing something!

Note: I can see that the categories are being created in the database. I
am just not being taken from the action to the rjs template.

Am running:
ruby 1.8.4 (2005-12-24) [i686-linux]
Rails 1.1.2
Using Webrick
OS: Ubuntu

Que 1: What am I missing or doing wrong?

Que 2: Am I right in understanding that Rails 1.2 has RJS template
support built in and I do not have to use edge rails?

Que 3: Is rake update_javascripts supposed to install javascript
libraries like prototype etc? If yes, when I execute that command should
I be seeing some output telling me whats being installed?

Thank you for sheding any light.

Okay, finally figured out my mistake. Had to remove add.rhtml from my
source code. This file gets generated when i ran script/generate
controller home index add. The conroller defaults to add.rhtml and not

The last thing I had to do was include:
<%= javascript_include_tag :defaults %>

you may want to use respond_to to avoid that problem.
