Rails - Mar 2007 - "reverse" routes - getting a controller and action from a URL

I''m using redirect_to :back in my app in one place.  In a couple cases
I need to see if the http referrer is a certain controller/action
pair, and do something differently based on that.  Is there some way
to get the url options from a url string?

Pat,

You want to take a look at
ActionController::Routing::Routes.recognize_path

I don''t know if you have the Pragmatic Agile book, 2nd edition.  If
so, check out page 398 (chapter 20, "Action Controller: Routing and
URLs").  If not, check out this example from my console:
>> ActionController::Routing::Routes.recognize_path "/users"
=> {:controller=>"users",
:action=>"index"}
>> ActionController::Routing::Routes.recognize_path "/users/5"
=> {:controller=>"users",
:action=>"5"}
>> ActionController::Routing::Routes.recognize_path "/users/5",
:method => :get
=> {:controller=>"users", :action=>"show",
:id=>"5"}
>> ActionController::Routing::Routes.recognize_path "/users/5",
:method => :put
=> {:controller=>"users", :action=>"update",
:id=>"5"}
>> ActionController::Routing::Routes.recognize_path "/users",
:method => :post
=> {:controller=>"users", :action=>"create"}
