How to return a specific object (not last one) in a Ecto.Multi chain

[joaquinalcerro]

So,

When you run Repo.transaction(), your Multi runs. This will return a map like this:

%{:ok, %{record: record, update_book: result}}

You can use this tuple un an case. For example check this post:

Best way to handle associations in single html form

Hi everyone, I have been learning a bit more on Ecto and Phoenix. Specifically in how to handle a master/detail o parent/child associations and the corresponding Web Form. My question: Is there a better way to handle this typical scenario than the one I implemented below? In my journey I read about: Ecto associations, multi, cast_assoc, put_assoc, embeded_schemas, transactions Drab Library Checktout many resources like: Phoenix, Ecto, Drab official documentation Different Forums: Medium,…

This example does not apply to your actual code.

Hope this helps.

Best regards,
