  Coincidentally, I've been working on a screencast series on YouTube the past couple of weeks and the very next video in it will cover setting up many-to-many associations and has-many-through associations.

    Excellent! The many-to-many relationships in Ecto still confuse me. Though, in my defense, most of my work is using embedded KV not SQL so Ecto is only for the UI form stuff.
