Hi.

I’m trying to make an Event Daemon so that upon a Version creation, it changes the ‘Status’ field’s value to ‘reference’, which I was able to do using ‘sg.update(…)’.

BUT, I want this change to to the ‘Status’ field to happen only once upon creation of that Version and NEVER AGAIN for that particular Version.

Is there a way to do this? If so, what’s the code to make that happen?

Some help would be appreciated.

Thanks in advance.

You should [read through the documentation](https://github.com/shotgunsoftware/shotgunEvents/wiki/Technical_Overview#event-types). You need the event type “Shotgun\_Version\_New”, which only fires when the version is created.  
If you do not listen to update events, then nothing will happen.

Conversely, if you have other `Shotgun_EntityType_Change` type events running, and you do not want them to run when the changes are happening at creation time of a new entity, each change `EventLogEntry` will contain the following in the metadata: `in_create: True` which can be used when filtering events on the plugins.

Also if you want _every_ `Version` to be set this status initially it may be worth simply updating the default value for the status field settings via the web UI.
