Cloning boolean custom fields does not work if their value is `False`

[peteeckel]

Deployment Type

Self-hosted

NetBox Version

v4.0.8

Python Version

3.11

Steps to Reproduce

1. Create a custom field 'test' with type 'Boolean', 'Is clonable' checked for an arbitrary object type, say ipam.IPAddress
2. Set the custom field to False for an arbitrary IPAddress object and click on 'Save'
3. Click on 'Clone'

Expected Behavior

The cloned object has its 'test' CF set to False

Observed Behavior

The cloned object has its 'test' CF set to None

If you look at the parameters of the URL for the 'Clone' button, the relevant part is test=. This is identical whether the CF 'test' was False for the original object or if it was undefined.

This is particularly relevant for required fields, as it makes it necessary to set the field explicitly for cloned objects even if cloning the field was enabled.

I did not run the NetBox test suite yet, but there seems to be a trivial fix:

(netbox) [root@dns netbox]# git diff

@peteeckel do you want to take this one?

Sure, I'll be glad to.
