I have a controller that renders a partial which looks like this: (traditional rendering)

render :partial => "feed", :object => @feed

question is: how can I call this method from the view and implement some cool AJAX where I get a loading spinner while the text is rendering then loads all at once?

I can do it with a form with this code:

(Toggle Plain Text)

<%= form_remote_tag :url => {:action => 'view'}, 
   :update => 'feed', :complete => visual_effect(:blind_down, 'feed'), 
   :before => %(Element.show('spinner')),
   :success => %(Element.hide('spinner')) %>

but i can't figure out how to implement the same type of comments when just calling the controller instead of having to use a form or a link (link_to_remote) in order access the content.

i'd be open to doing away with the controller and just having all the code in the view area, but i'm still looking to have the AJAX before/success elements implemented.

Thanks in advance for the help!

I have it figured out. I pulled the javascript from the source and put that in a body onload tag.

thanks all!

I did something with ajax on my rails site (http://boozrs.com) . The thing is I never could get the form_remote_tag to work properly with :update => 'someId', but something like this does work:
In view:

(Toggle Plain Text)

<%= image_tag('/images/indicator.gif', :border => 0, :id => 'posting', :style=> 'display: none;') %>
		<% form_remote_tag(:url => {:action => 'comment', :user_id => session[:user_id]}, :before => "Element.show('posting')", :success => "Element.hide('posting')") do %>
			<p><label>Comment</label><br/>
			<textarea name="comment" rows="10" cols="50"></textarea></p>
			<input type="submit" value="Add A Comment" />
		<% end %>

And the controller:

(Toggle Plain Text)

def comment
  #do stuff here specific to what you want to do
  render :update do |page|
    page.replace_html  'comments', :partial => 'comments' #you can pass objects and other stuff here, if you want
  end
end
