Instance variables in application layout

Rails
1

Hi

I have an application layout, and in it there is a sidebar. What i
want to do is put things like tags, newly registered users, recent
comments, etc in the sidebar.

I am not sure how to do this…

What controller does the application layout access instance variables
from? I presume you can use the application controller, but am not
quite sure how…

The controller that is rendering the current action (what other one
could it be?).

If your site has a global layout
it’d be quite normal to have the following lines in application.rb

class ApplicationController

layout ‘application’
before_filter :set_layout_variables

def set_layout_variables
@stuff = Stuff.find(:all)
end

end

Then all controllers will inherit this before_filter and by default
render their output into the layout
/app/views/layouts/application.html.erb
