custom field slug with '/' might break UI

[sklemer1]

Environment

• Python version: 3.7.3
• Nautobot version: 1.3.2

Steps to Reproduce

1. Create a new custom field named Devices / Virtual Machines
2. Go to https://mynautobot/extras/custom-fields/
3. You get

<class 'django.urls.exceptions.NoReverseMatch'>

Reverse for 'customfield' with arguments '('Devices / Virtual Machines',)' not found. 1 pattern(s) tried: ['extras/custom\\-fields/(?P<name>[^/]+)/\\Z']

Python version: 3.7.3
Nautobot version: 1.3.2

Expected Behavior

Impossibility to add such a slug and/or correct URL reversal.

Observed Behavior

Python Exception and need to remove the broken cf via nbshell.

TODO

• Add a slug field and use it in URL patterns

Thanks for the report! #824 is the tracking issue for changing the CustomField model to actually make this field a proper slug field, which would fix this issue and several related symptoms.

[bryanculver]

As a bug fix, we will add a slug field and use it in URL patterns.

[glennmatthews]

Fixing this the "right" way will require adding a versioned REST API serializer, I think - so moving this to 1.4 milestone.

Implemented for 1.4 by #2136.
