Rails - Oct 2006 - routes.rb priorities and REST resources; Bug or documentation vagueness?

I came across this little annoyance(?!) while upgrading a project  
from 1.1.6 to Edge Rails.

I was trying to add a resource mapping for my Post model.

I did as instructed and added...

	map.resources :posts

...to config/routes.rb. What I didn''t pay much attention to was that  
I added the command to the very end of the file (before the
''end''
keyword of course; I am not that thick!).

Anyway, everything seemed to work fine until I tried a CRUD operation  
other than the ''/posts'' index action. I started getting
strange
''Unknown Action 2'' messages.

Well, it took me a couple hours to figure it out; any mapped  
resources must be added *before* these two lines in routes.rb:

   	# Install the default route as the lowest priority.
	map.connect '':controller/:action/:id.:format''
	map.connect '':controller/:action/:id''

I haven''t had a chance to investigate if this is a routing bug (the  
code looks a tad scary!). Or maybe it is just a vague point in the  
documentation (i.e. routes.rb comments)

I fear this little detail might get in the way of a lot of people who  
are eager to jump into REST, and might not spend enough time to read  
the comments, even if they are in front of them.

Before REST it might not have been an issue as simple apps never  
touched routes.rb. Now though...

Routes go from top to bottom.  This has always been a key point with routes.

I find myself actually removing the default open connect route and
only going with explicitly set routes/resources.

and this is much more important if you want to somehow limit your app
to what is offered as a restful resource since if you don''t remove the
default routes then the canonical actions will be available!
