Hi I am trying to figure out the "right" way to do this.

In my application every time I create a new user I want to have specific data loaded into an associated table. The associated table is a different preset lists. So a User has many lists and those lists have many items. Some of those Items I want to be loaded when the User is created.

I really don't know how to go about doing this but I am guessing something like: create User after_create: create Lists (need already existing data for the list names) after_create List then populate Items table with existing data for these Lists.

Should I be using seed data for this? Is that alright for production and if so how exactly would I go about doing that.

Any guidance or other recommendations are greatly appreciated.
