Example or video of a parent-child data relationship

Is there a video that explains how to code a one-to-many data relationship?

As a simple example, how would I code a Shopping List application where I have a list of favorite stores and the ability to add shopping items to specific stores?



There’s no video about that from AppGyver, but I’m sure there’s lots of other resources and videos elsewhere that can be applied to creating the structure in Composer. If you plan on using an external database maybe that provider has some tips for it. By your explanation I would guess a simple Store database with the list type property shopping_list would do the trick.
