Hey,

where exactly are these methods defined? I’d like to use alias\_method  
to set some parameters before calling the original methods.

Cheers,

They’re defined by the map.resources calls in routes.rb. You could  
probably alias them anytime after that file is executed…but why? You  
can set parameters when you define them.

What are you trying to accomplish?
