Unable to create Racked Device through REST API when defining Variable "face"

[2muchgit]

Environment

• Python version: 3.7.7
• NetBox version: 2.8.0
• we are using netboxcommunity/netbox:v2.8.0-ldap

Steps to Reproduce

1. Create all necessary Objects for creating device:

• Device Type
• Device Role
• Site
• Rack

2. Creating a Device:
   curl -X POST -H "Content-Type: application/json" -H "Authorization: Token <TOKEN>" -H "Accept: application/json; indent=4" http://netbox.test/api/dcim/devices/ --data '{ "name": "teststuff", "display_name": "teststuff", "device_type": { "id": 43 }, "device_role": { "id": 2 }, "site": { "id": 27 }, "rack": { "id": 300 }, "position": 1, "face": 0, "status": 1 }'

Expected Behavior

Receive HTTP 200 from the web-server.
Device with name "teststuff" should be created and mounted to its rack position

Observed Behavior

Netbox:

Exception Type: AttributeError at /api/dcim/devices/ Exception Value: 'UniqueTogetherValidator' object has no attribute 'set_context'

Web-server:
[21/Apr/2020:10:12:15 +0000] "POST /api/dcim/devices/ HTTP/1.0" 500 22793 "-" "curl/7.58.0"

Notes

When sending the request, "face" seems to be the only argument whose value is not being accepted:

curl -X POST -H "Content-Type: application/json" -H "Authorization: Token <TOKEN>" -H "Accept: application/json; indent=4" http://netbox.test/api/dcim/devices/ --data '{ "name": "teststuff", "display_name": "teststuff", "device_type": { "id": 43 }, "device_role": { "id": 2 }, "site": { "id": 27 }, "rack": { "id": 300 }, "position": 1, "face": "front", "status": 1 }'

Using "front" or "rear" Returns the same error as previously shown.

Any other value for "face" returns a proper response:
curl -X POST -H "Content-Type: application/json" -H "Authorization: Token <TOKEN>" -H "Accept: application/json; indent=4" http://netbox.test/api/dcim/devices/ --data '{ "name": "teststuff", "display_name": "teststuff", "device_type": { "id": 43 }, "device_role": { "id": 2 }, "site": { "id": 27 }, "rack": { "id": 300 }, "position": "2", "face":"bla", "status": 1 }'

{ "face": [ "bla is not a valid choice." ] }

curl -X POST -H "Content-Type: application/json" -H "Authorization: Token <TOKEN>" -H "Accept: application/json; indent=4" http://netbox.test/api/dcim/devices/ --data '{ "name": "teststuff", "display_name": "teststuff", "device_type": { "id": 43 }, "device_role": { "id": 2 }, "site": { "id": 27 }, "rack": { "id": 300 }, "position": "2", "face":"", "status": 1 }'

{ "face": [ "Must specify rack face when defining rack position." ] }

curl -X POST -H "Content-Type: application/json" -H "Authorization: Token <TOKEN>" -H "Accept: application/json; indent=4" http://netbox.test/api/dcim/devices/ --data '{ "name": "teststuff", "display_name": "teststuff", "device_type": { "id": 43 }, "device_role": { "id": 2 }, "site": { "id": 27 }, "rack": { "id": 300 }, "position": "2", "face":{"id": 0}, "status": 1 }'

{ "face": [ "Value must be passed directly (e.g. \"foo\": 123); do not use a dictionary or list." ] }

Looks to be the same issue as #4496. Will be fixed in v2.8.1.
