Deployment Type

Self-hosted

NetBox Version

4.3.1

Python Version

3.10

Steps to Reproduce

set up webhook
set up event rule on "Object Update" with condition:

{ 
  "and": [ 
  { 
    "attr": "status.value", 
    "value": "active" 
  }, 
  { 
    "attr": "{{ snapshots['prechange']['status'] }}", 
    "negate": true, 
    "value": "active" 
  } 
  ] 
}

trigger the update

Expected Behavior

Triggered only when the status of object changed from any to 'active'.

Observed Behavior

It was working on my old Netbox, but now I have killed it and recreated new instance and use the same condition but it is triggering every time if the status if 'active'. Seems like "and" does not work or second part of condition wrongly declared.

@arthanson Hi, could you please assign it to me, I need this function on my prod enviroment, because it will drop a lot of unnecessary, I want to combine snapshots and data to impliment this request.

@VladyslavTkachenkoDesy Hi, I've check in my demo 3.1.7 and I didn't find this functionality, so it's "The Mandela Effect" or it was dropped earlier.

@arthanson @jeremystretch Hi, I don't think that it is a bug (it's new feature), but I've tried to add functionality to use snaphosts in condition in https://github.com/netbox-community/netbox/issues/18159. If there is no objection I suggest to close this task and assign https://github.com/netbox-community/netbox/issues/18159 to me, I'm ready to create pull request.

@VladyslavTkachenkoDesy what you're trying to do is not currently supported (and never has been). I suspect you're confusing the template context available within a webhook with the conditional logic for an event rule. Please see FR #18159 as referenced above.
