First, your eval string should be:
  eval "#{id} = '#{value}'"
id and value are replaced to form the expression:
  eval "foo = 'this is the value'"
which is OK with irb. But it doesn't work with ruby, and it's explained
here: http://tinyurl.com/2vc4u . One solution would be to use a hash to
store id, value as key, value...
