Hello! I'm at my very first application in Rails, and I'm learning from Agile Development with Rails. I'm developing a web app that is run as a questionary. The idea is to create a database of questions (like 50), but use only like 10-15 each session, for each user. You can start the questionary only if you give your email address(validatates_presence_of). The point I'm wondering about is : since the answers are multiples and the sessions too, how can I keep track about whose belong certains answers? Shall I haven't a pool of mixed answers? I was thinking about a migration with 16 slots (email, and 15 slots for each answer), could that work? I know it's not exactly in the DRY logic, but in this way I'll have a complete table, with which I could also calculate how many correct answer the user did, and statistics stuff like that.
