I have a partial named “\_mailing\_list.rhtml” ~

\<% remote\_form\_for(:recipient, :url=\> { :controller =\>  
‘recipients’, :action =\> ‘create’ }) do |f| %\>

Email: \<%= f.text\_field :email\_address, :size =\> 20 -%\> \<%= submit\_tag "Subscribe", :disable\_with =\> "Please wait..." %\>

\<% end %\>

I have a create action in my recipients controller ~

def create  
@recipient = Recipient.new(params[:recipient])  
@recipient.save  
end

I have a create.rjs ~

page[:mailing\_list].reload

The Recipient ActiveRecord correctly updates the database and the RJS  
creates the JavaScript I want, but rather than executing the  
JavaScript, I see it printed to my screen and the URL changed to /  
recipients/create

What am I doing wrong?

Thanks,  
Dan

Have you included the prototype.js library in your layout?

\<%= javascript\_include\_tag :defaults -%\>

Yes, and the source file shows prototype.js, etc. included.

Have you updated the default javascript files since you created your  
rails project? I don’t know exactly why that might break your code,  
but I had the same problem you’re describing after I tried to update  
the prototype and scriptaculous files to the latest versions. Once I  
reverted back to what shipped with my version of Rails, my RJS  
templates worked again.
