The reason that I am trying to use methods/attributes to store the information rather than an array is because this model is used to create a batch update form in a Rails project. If one of the updates fails then I want to display the errors on the form next to the relevant fields. For this to work, I will need to use the error_messages_for helper to which I need to pass the attribute. Am I approaching this in the correct manner? -- Posted via http://www.ruby-forum.com/.
