48: Ecto Associations with Sheharyar Naseer

We talk with Sheharyar Naseer about Ecto's feature "association defaults" and how they work. We learn how they even support defining a function that gets called during your changeset operations which can be used to ensure multi-tenancy IDs get populated correctly. We learn more about Slab, talk about Single Table Inheritance designs and how we feel about them. We also talk about wrapping the Repo module for fun and profit!
