Filtering routes based on format

Hi,

We've had some requests though for nonsense URLs which have slipped through to our controllers and caused ActionView::MissingTemplate exceptions. They're from URLs like

    /artists/123-radiohead.php

I feel like it should be possible to block this request at the routing stage - before it reaches the artists controller, but I can't see how it could be done. We use restful routes, so the artists controller is wired up using

    map.resources :artists

Is there any way to add an option to this call to specify the formats that are acceptable (and thus return a 40x code if the format is not in the whitelist?)

e.g.

    map.resources :artists, :format => [ :html, :json ]

I can't see anything in the docs, or indeed the code, which would let me do this, but I might well have missed something.

cheers, Matt

For routing information you could read here: http://api.rubyonrails.org/classes/ActionController/Routing.html

I'm guessing you could use regular expressions or something else to reduce the actions that could be called on a given controller.

Another thing you could do is use method_missing and redirect to an error page, I guess.
