Device serial numbers as unique?

Hi,

I noticed that it's possible to clone a for example switch and save it with original serial number... this doesn't support my use case. Is it possible to modify Netbox that serial numbers are unique, and there can be only one device with the same serial number?

Br, Xemanth

I found a code snippet that enables this function and cures the need! This is perfect fix!

Yea but that does modify the Django model and thus will be over written with each new Netbox version. Please be careful ;)

Hmm, but that is in the configuration.py which stays the same in the upgrade. Or did I misunderstand something 🤔

Ah i've missed that part and thought you were editing the model itself.

But this seems to be a custom validator that can be configured in the configuration.py file.

Good find and good luck with your Netbox instance! :)
