Understood! So your datastructure has the order information embedded as an array, so you’ll only have one changeset and the information is ephemeral and shouldn’t be persisted, correct?
In that case, I would probably use a single form around the table, so that I can still use the error tracking provided by the Ecto/LiveView integration. Then it comes down to something like this: How to use a list of items (array) with LiveView form
But in principle your implementation would also work
