All,

I am attempting to do an IO.read call on a file inside of one of my  
model objects.

I keep getting Errno::ENOENT

The path I’m passing to IO.read is relative to RAILS\_ROOT.

Two questions:

1. This code was previously executing in my controller - it it  
significant that I moved it into my model?

2. Is there some way to verify which directory is the current directory  
for the app.?

Thanks,  
Wes

I just verified that I can run this same call in my controller object  
without a problem.

I thought I was.
