This worked beautifully! love the solution.

Just for fun, I used:

  Object.const_get(class_name).create(:item_name => item_name)

Note how i had to use .create instead of .new... This probably has to do 
with Rails, so I'll take it to the Rails forum. But this has really 
straightened out my understanding of Ruby's nested arrays, hashes, and 
blocks.... Thank you!
