Re: [Rails-devel] Tracking Down Errors

Yes, the output that generates a list of related method/function calls that caused the error is called a "stack trace". It traces it's way up the call stack. There's only three lines in the stack trace relevant to the rails code itself, so those are likely to be where the error is. From there, it's just a matter of understanding what the code is doing or could have been doing that would have caused the failure. ---Brett.
