Rails - Dec 2005 - No javascript fallback

AJAX is good for a lot of things, but javascript is not always 
available.

I think the new RJS templates are very good:
http://www.codyfauser.com/articles/2005/11/20/rails-rjs-templates

And they could be used to create a simple, automatic no javascript 
fallback. An example:

You have a controller called PostsController. There is an action
"new".
The view displays a form. The form will be submitted to the 
"create"-action using AJAX, and if the user doesn''t have
javascript
enabled, it will be submitted to the create action anyway. It looks like 
this:

class PostsController < ApplicationController
  def create
    @post = Post.new(params[:post])
    @post.save
  end
end

This creates a new post. There are two views: one create.rhtml and one 
create.rjs. Create.rhtml is just usual ruby-html code and create.rjs 
contains javascript code that will be executed. Rails determines which 
template to use with request.xhr?. If this is an xmlhttprequest: render 
create.rjs, else render create.rhtml.

Would it be possible to do this with an after filter? The filter checks 
if there are two templates: #{action}.rjs and #{action}.rhtml and 
renders the correct one.

I will need to change the view helpers too to add automatic ajax and non 
ajax submit.

Is this a good idea? How could the view helpers be implemented?
