Rails - Mar 2010 - Routing optimisation

I''m kind of a newbie, so I don''t understand all the power of
routes and implicit render that can be found in scaffolding

I  have an application that have several views which are quite different but
based on the controller action.

What I would like is to be able to define routes that would go through the same
controller action but would diverge on various views

Something like

/display/:id/:variant

would go to :action=> display and then 
the render would go to display_variant
Right now, all I can do is to render the display.html.erb

Or maybe
/display_variant/:id

would do the same

I would be able to have then urls such as
/display/25/tall
/display/25/wide
display/25/mix

and I would only design 
display_tall.html.erb
display_wide.html.erb
...

Any thoughts ?

Thanks in advance

Christophe

This is probably best done with CSS... ie max device width.  However, you could
leverage the format option in rails.  Normally you get things like .html, .js,
.xml as pretty standard.  In your case, the "variant" could just be a
format (iPhone is a pretty typical one).  Basically add another view file, like
display.js.erb or display.iphone.erb or display.tall.erb.  You may need to
define the mime-types for the non-standard ones.
