[Controller Hooks] Difference between on_update and on_change

I was wondering, what’s the difference between on_update and on_change regarding Controller Hooks.


This is ranking high on google.
Can someone please shortly elaborate on this?
Thanks :slight_smile:

Can someone please explain this?!

Taking a look at the code, it appears that the difference comes into play around the submissions feature. The on_update hook is only triggered when the form is saved or submitted. The on_change hook is fired in those instances but is also fired when the document is cancelled or when it is updated after submit.

on_change also fires when you delete a document.
