It depends on the logic > 3. And I have not created any association between any of the models. Why not? Are they not related? > > What I want to do: > 1.

Member.where(status: "active") will give you the members, then you can use each to get member.member_code > 2.

However if you have the same information in two models it is very likely that you database design is poor.

I suggest that before doing anything else you work right through a good tutorial such as railstutorial.org (which is free to use online), including all the exercises. That will show you the basics of rails. > > Can I do this without creating associations? Or is it compulsory? Nothing is compulsory.
