Re: [Rails] Ruby code on Chef as a "ruby_block" not working

You should really ask about this in a chef support area, as it is something very specific to chef.

As it is, you cannot define local functions in chef recipes, they have to be defined in libraries and called from such.

Stackoverflow is really your best bet for help on chef things, or the #chef channel on irc.freenode.net
