I am trying to learn the Ruby behind Rails and it would be helpful to  
be able to find the Ruby code for a given method.  
For example I am in Script/console and I do: “puts  
ActiveRecord.methods”. I get a nice list.  
Lets say I want to explore the mattr\_accessor method. Is there a  
command or method that would give me the Stack Trace to that piece of  
Ruby code?  
I am using Windows Grep to find it now and that doesn’t usually work  
as many of the methods are added via class\_eval from somewhere far far  
away.

it turns up in:  
C:\ruby\lib\ruby\gems\1.8\gems\activesupport-2.0.2\lib\active\_support  
\core\_ext\module\attribute\_accessors.rb

Typing in some Ruby Magic like ActiveRecord.mattr\_accessor.ruby\_path  
would be really cool. But, I suppose the methods added by “included”  
callbacks are going to be invisible… Tell me it isn’t so!

Thanks in advance
