Rails Cookbook review

Guys:

Stuck at the mall today, and just had to crack Rails Cookbook, by
O’Reily. It
had a recipe for accepting dynamically created forms. The sample output
looked
like this (reconstructed):

p params[:my_form]

[“1-1” => 0, “1-2” => 0, “1-3” => 0, “2-1” => 0, “2-2” => 0,
“2-3” => 0, “3-1” => 0, “3-2” => 0, “3-3” => 0]
