Is there a way I could get some account fields using account-link field of collection without a second call to /listUsers or creating a new endpoint? Like an SQL INNER JOIN
I had to follow solution n.2 from here
You must create a folder
\cockpit-master\config (if it doesn’t exist) and add a file
bootstrap.php in which you will add implementation to handle the event of
collections.find.after.collectionName and you will be able to do extra database calls and add content to the response before it is returned to the client. (see example).
