Rails - Jun 2005 - Passing vars between controllers

Is it possible to pass vars from one controller to another during page
rendering?

For example, I have a navigation controller which is included in a
template via a render_component call. The navigation controller
decides which links belong to any given page, so navigation logic
which is changeable can all be located in that controller. However,
certain links, obviously, require certain vars at times, such as ids
for various other controllers, in order to properly render an
appropriate navigation url.

These vars are usually passed to the controller responsible for
rendering the page, not directly to the navigation controller. I
*could* simply add needed parameters to the parameters hash in the
render_component method, but not every page needs parameters passed to
the navigation and there are other inconsistencies depending on which
page you''re going to.

So, to restate, I''m wondering if there''s another way to
arbitrarily
pass vars to the navigation controller, as needed, from the controller
responsible for rendering any given page.

Thanks for any input.

All the best,
Greg

Have you considered using sessions?
