Proposed Changes

Since netbox-community/netbox@d4f8cb7, netbox.configuration has changed DATABASE to DATABASES (plural). This change should be reflected in this plugins setup documentation.

Therefore the following change in the local_settings.py is required for netbox >= 4.3:

-from .configuration import DATABASE
+from .configuration import DATABASES
# ...
-DATABASES = DynamicSchemaDict({
-    'default': DATABASE,
-})
+DATABASES = DynamicSchemaDict(DATABASES)
