Hello there, dear community! I have been dealing the last days with a function that save multiple records at once using Ecto.Multi. At the moment on my code I have 2 functions that successfully works (yeey :tada:) using Multi too. The logic of this function is to take the Attributes comming after …

When I need to iterate on stuff I sometimes use Ecto.Multi — Ecto v3.14.0 . In your case you should also notice that you’re not making a unique key per each insert. Instead of using :insert_membership you should either use a tuple like {:insert_membership, something_unique_here} or just a key with a…

The key can be any term, so you can do update_group = {:update_group, index}. This should help you remove the repetitive code.

That’s a super long function. Break it apart a little bit. :slight_smile:
