Rails - Mar 2008 - What's the most compelling way to do AJAX/Interactive applications with Rails?

Hi,

So as I''ve said before, I''m coming to Rails from ColdFusion. 
In
ColdFusion 8, there is are strong, albeit somewhat templated AJAX
features.

What sort of options are out there for AJAX with Rails?

Thanks,

Ron

The "keyword" you may want to look into is "rjs templates".
These are
ruby templates that allow you to "render" ajax actions and javascript 
effects. Other useful keywords to look into:

- remote_form_for
- form_remote_tag
- link_to_remote
- observe_form
- observe_field

Also, look here:

http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper/JavaScriptGenerator/GeneratorMethods.html
http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html


It may take a little bit of time to become familiar but it is 
surprisingly easy to use javascript and ajax rails.

# /app/controllers/posts_controller.rb
def create
  @post = Post.new(params[:post])
  respond_to do |format|
    if @post.save
      format.js # renders create.js.rjs template
    else
     #...
    end
  end
end

# /app/views/posts/create.js.rjs
page.insert_html :bottom, ''posts-list'', :partial =>
"post_item", :object
=> @post

That is a quick example of how easy it is to set up an rjs action. That 
is the basic code for having someone create a post which shows up on 
screen using ajax to load the new post.

Hi Ron, coming from CF myself, I''ve faced the same issues.  I  
originally tried using RJS (baked into rails), but it left me with the  
same feeling of using cfform tags.  I''m also a fan of unobtrusive  
javascript and I couldn''t find an easy way to use those principles  
with rjs.

Currently, I''m creating a new app that uses dojo toolkit. 
It''s an app
all done on one page (the public/index.html file) that uses all the  
rails controllers as json providers.

I like not being tied to one library.

Definately check out:

Unobstrusive Javascript for Rails. Awesome plugin that allows for 
applying those principles with rjs.

It''s not supported anymore, Dan Webb posted his reasons and
he''s
perfectly right. Use LowPro instead and do it in Javascript itself.  
Using Rails 2 it''s perfectly possible to generate javascript with erb  
parsing and combining that with LowPro, you have a pretty powerful  
tool at hand.


Best regards
