Fixes : #3070 Add the decommissioning status for devices

[clercrobin]

Fixes : #3070

Environment

• Python version: 3.6.7
• NetBox version: 2.5.10

Proposed Functionality

To extend the issue #154, we want to add a status decommissioning to the already existing status list:

• offline
• active
• planned
• staged
• failed
• inventory

Use Case

We are currently using Netbox as our asset management system, in addition to its DCIM functionality and are quite happy with this. A valuable output from Netbox would be a forecasting vision enabled by a status like planned. However it is not sufficient to complete this functionality and thus to indicate that a machine will be soon offline we want to add the status decommissioning.

It would enable the 2 following views:

• Current status: Active + decommissioning
• Forecast: Active + planned

Database Changes

The device statuses lines (314 - 328) of the file netbox\dcim\constants.py would change to:

STATUS_OFFLINE = 0
STATUS_ACTIVE = 1
STATUS_PLANNED = 2
STATUS_STAGED = 3
STATUS_FAILED = 4
STATUS_INVENTORY = 5
STATUS_DECOMMISSIONING = 6
DEVICE_STATUS_CHOICES = [
    [DEVICE_STATUS_ACTIVE, 'Active'],
    [DEVICE_STATUS_OFFLINE, 'Offline'],
    [DEVICE_STATUS_PLANNED, 'Planned'],
    [DEVICE_STATUS_STAGED, 'Staged'],
    [DEVICE_STATUS_FAILED, 'Failed'],
    [DEVICE_STATUS_INVENTORY, 'Inventory'],
    [DEVICE_STATUS_DECOMMISSIONING, 'Decommissioning'],
]
