Stuck with Diode plugin migration

[gtomilko]

Got catch 22:

(venv) [root@vm-gdi-netbox netbox]# python3 /opt/netbox/netbox/manage.py migrate netbox_diode_plugin
Operations to perform:
  Apply all migrations: netbox_diode_plugin
Running migrations:
  No migrations to apply.
  Your models in app(s): 'netbox_diode_plugin' have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.
(venv) [root@vm-gdi-netbox netbox]# python3 /opt/netbox/netbox/manage.py makemigrations netbox_diode_plugin
CommandError: This command is available for development purposes only. It will
