Subject: Re: How to cycle through an instance

Have you try something like this:

@student = Student.find(params[:id])

@student.attribute_names.each do |attr_name|
  puts "#{attr_name} => #{@student.attribute[attr_name]}\n"
end

or

puts @student.attribute_names.map { |attr_name| "#{attr_name} => #
{@student.attribute[attr_name]}"}.join("\n")
