ArcGIS Online - Calculate Field Automatically

[BenGrod]

When editing an ArcGIS Online hosted feature layer within a web map or web app is there a way to automatically calculate a field upon creation of the feature? I am trying to automatically calculate the area (square feet) of a polygon after it is created.

In ArcGIS Desktop you would have to use the Attribute Assistant Add-In: Attribute Assistant | ArcGIS Solutions

But sadly this will not solve your issue, since this only works in ArcGIS Desktop.

well, it sounds like this is a feature esri should look into and enable. I will enter it into their idea page, if its not done already.

edit: alas! this is already implemented. See link here

It would be nice if the Ideas page could list dates on the implementations (or even on the different statuses like "reviewed" or "considered", etc.)

i am searching for the same functionnality.

Possible programmatically in the front office without using esri tech. (i use jsp,javascript to pass sql transactions to the database)

Possible by creating trigger in the database.

but on the cloud i don't know.

Anyone here in 2021 please upvote idea supporting Attribute Rules in ArcGIS Online to enable this.
