Sharkie, I would recommend reading the following first before you start
upgrading from Rails 2.x to Rails 3.x:
http://blog.peepcode.com/tutorials/2010/live-coding-rails-3-upgrade
Next, link_to_remote has been deprecated in Rails 3 and you would
need to do the following:
<%= link_to "XXX", { :remote => true }, { ... } %>
> def hide_dock
> render :partial => "/layouts/dock"

Next, the above shouldn't use raw because link_to method
returns an html_safe string in Rails 3.

If you're using RJS, then you'll simple add
the expression to be executed. For example,
I tend to be partial to JSON and I would do the
following:
format.js # render the action.js.rjs by default
or you can redefine it as follows to return json
format.js { render :json => @some_object }

It's not clear as to what you're trying to do. The hide_dock is a
controller
action so do you want to allow the following:
http://some_domain.com/controller_name/hide_dock

If you intend on using jQuery, then there's no need to use RJS. Just make
sure that you get the JS file here:

If you're updating just a part of the page, then you'll need to use the
above.

Lastly, I would recommend getting the PDF for "Agile Web Development with
Rails 4th Ed" by Sam Ruby, Dave Thomas, et al from pragprog.com for
additional
information regarding the questions that you have above.
Good luck,
