If you need videos my search was successful and found a lot but that specific one eludes me as well.
In any case if you want eleixir conf videos this is what I found https://www.youtube.com/results?search_query=elixir+conf
Maybe this might help:
-
Also I am wondering if not the ecto multi, can be used here. https://hexdocs.pm/ecto/Ecto.Multi.html.(can make several repo actions like multiple inserts)
-
The changeset also can prepare queries and add to them.
Ecto.Changeset — Ecto v3.14.0(modify structures and validate them)
