Joël contributes some thoughts on working with custom attributes as he follows up on last week’s discussion about ActiveModels with Sally. Joël breaks down how he transforms various strings and objects when working with ActiveModels to simplify more advance workloads, as Sally queries their different use cases and how best to utilise them for her own workflow. — Catch up on Sally and Aji’s episode from last week on ActiveModels before diving into this discussion!
