I’m new to Ruby/Rails and doing pretty well and liking it a lot.  
However, deep into one of the tutorials, I was feeling so confident that  
I went several pages (read: hours) without double-checking that my  
changes were still working. When I finally got to the part where I  
thought “ok, I better check on this and see how it’s looking”, I got

Routing Error:  
no route found to match “myapp” with {:method=\>:get…

etc.

(I’m OS X 10.4.9, up to date Ruby/Rails/Gems and Safari/FF/OmniWeb  
browsers.)

I figure it’s some simple thing that I changed or left out – but what I  
can’t figure out is how do I determine WHICH simple thing I changed or  
left out?

So: I’m not asking you to debug this one for me, I’m asking how do I go  
about debugging this somewhat vague-seeming message?

Thanks!

Hi,

Check to make sure you have a myapp\_controller.rb… The error message  
is stating that Rails cannot find your controller class.
