"fallback" routes

Hello list!

Is there a way to have a “fallback” route? Like if I have one :cat,:album,:item connected to AlbumsController.show, let’s say the :cat, :album or :item were invalid so other route would try to handle it.

The logic would be like this:

  • Check if there’s an album/cat/item if not;
  • Check if there’s an section/subsection/subsubsectio

n

  • and so on

Of course I could add a string prefix to the route to make it unique like this: /pages/:section/* but it wouldn’t be as clean as :section/*.

(Note: I’m not sure on how to handle unlimited arguments in the route in the case of the subsections example, I just put * as an way to tell that there might be a unknown number of subsections, so if someone could also enlighten-me on this one, I would be grateful!)

Thanks,

Marcelo.
