Looking for a PDF document with relation of ActiveRecord

Hi all,

There was some months, I found on this mailing list a PDF document,
explaining the database relations (belong_to, has_many, ... ) in
ActiveRecord with pictures. Any idea, where can I find this document ?

Thanks,

Stephane

Perhaps you are thinking of this:
http://slash7.com/cheats/activerecord_cheatsheet.pdf

Or this...

Thanks, it's the second file (png) and not a PDF.

Thanks
