Selecting records according to an item
You want to use classify and constantize:

require 'set'
AUTHORIZED = Set[Product, Status, Industry]
def get_record(id, item)
  model = item.classify.constantize
  raise "Go away, hacker" unless AUTHORIZED.include? model
  model.find(id).name
end


Be careful about security, as without the unless this will access any class in your system. This is just an example.
