Rails - Sep 2005 - MissingSourceFile in <controller not set>#<action not set>

Hi all,

I am having trouble with a Rails error that I do not understand. I
found a thread on the Textdrive forums about this, in which the
proposed solution was essentially to recreate the Rails app directory.
I did this once, and it seemed to work, but I have encountered the
error again and tried the same solution with no effect.

The subject line of this message is the primary heading on the error
page. Here is the rest of that page:

------------------------------------------------------------

         This error occured while loading the following files:
   ./../config/../config/routes.rb
      
Request 

Parameters: None
--- {}
   
Response Headers: {"cookie"=>[], 
"Cache-Control"=>"no-cache"}

Oh, and just in case: yes, the file is actually there.

Is this like a total newbie error or something? I''ve searched, but
couldn''t find anything more relevant that the Textdrive post which I
described.

Any help would be greatly appreciated. Thanks.

It is there, but is it readable? Readable by the user running webrick?

I dunno why it wouldn''t be. I''m running the stuff locally, and
I''ve
not changed any configuration of anything. I''ve gone through some
other tutorials with no problems, and as I said, I even had the
current project functioning at one point.

Ray,

I double checked the read status of the directory, and sure enough
some of it was read-only. I didn''t assert whether or not routes.rb was
one of those, but made the whole directory writeable. This seems to
have fixed it!

Thanks. :)

Gah! Spoke too soon!? :..(

1. Run rails command to create a new app directory
2. Edit database.yml to point to the MySQL database that is already created
3. Run "generate scaffold user User" to generate scaffolding to map to
"users" table in database
4. Run server script
5. Go to view the scaffolding and I get this error again... ensuring
that the whole dir is readable does nothing, even when restarting
webrick

I am starting to worry that the simple tutorials that hook people in
are not telling the whole story... but also, I know I am a newbie with
a lot of this. I just do not see this issue coming up, and nobody has
yet provided a "this is exactly what that is and here''s what you
do"
for it.

I think I found this page earlier:

http://www.glenswinfield.co.uk/general/ruby-on-rails-errors/

But overlooked this detail:

"run script/server inside of the top-level directory of your app"

I had been entering the /script/ directory to save myself a few
keystrokes when running the generators. Is this a bug, or what I get
for being uber lazy? ;-p

All seems okay now... oy!
