Deployment Type

NetBox Cloud

NetBox Version

v4.2.7

Python Version

3.10

Steps to Reproduce

1. Open a device and click "edit" to bring up the edit form.
2. In a second tab, do the same.
3. In the first tab, set the device's description to "foo" and click "save." The device should be updated successfully.
4. In the second tab, set the device's description to "bar" and click "save."

Expected Behavior

The second form submission should raise a validation failure:

This object has been modified since the form was rendered.

Observed Behavior

The device is saved successfully, overwriting the first description.
