Nautobot v1.5

This document describes all new features and changes in Nautobot 1.5.

If you are a user migrating from NetBox to Nautobot, please refer to the "Migrating from NetBox" documentation.

Release Overview

Added

Custom Field Grouping (#899)

Custom fields can now be assigned to a free-text "grouping" to improve usability when a large number of custom fields are defined on a given model. In the UI, fields in the same grouping will be grouped together, and groupings can be expanded/collapsed for display purposes.

Device Redundancy Groups (#1892)

Device Redundancy Groups have been added to model groups of distinct devices that perform device clustering or failover high availability functions. This may be used to model whole device redundancy strategies across devices with separate control planes (ex: ASA failover), not devices that share a control plane (ex: stackwise switch stacks), or interface specific redundancy strategies (ex: hsrp). Device Redundancy Groups support grouping an arbitrary number of devices and may be assigned an optional secrets group and one or more optional failover strategies.

Custom Celery Task Queues (#2421)

A new optional job property task_queues has been introduced to allow Nautobot to leverage custom celery queues for jobs. This will allow you to send jobs to specific workers based on which queue is selected. This property can be set on the job class and overridden in the job model, similar to other overridable job fields. If task_queues is not defined on the job class or job model, the job will only be able to use the default queue. A new field has been added to the job run form to allow you to select a queue when you run the job and an optional field task_queue has been added to the REST API job run endpoint for the same purpose.

The default celery queue name has been changed from celery to default. If you have any workers or tasks hard coded to use celery you will need to update those workers/tasks or change the CELERY_TASK_DEFAULT_QUEUE setting in your nautobot_config.py.

Added nautobot-server generate_test_data command (#2536)

A new management command, nautobot-server generate_test_data, has been added that can be used to populate the Nautobot database with various data as a baseline for manual or automated testing. This is now used internally by Nautobot's unit testing suite to create a synthetic data set that looks and feels like real data with randomly-generated values. Most importantly, the objects are created with all of the fields fully and correctly populated, to assert that each object in the database is properly exercising all features.

!!! warning
Be very cautious about running this command on your server instance. It is not intended to be used in production environments and will result in data loss.

Nestable LocationTypes (#2608)

LocationType definitions can now be flagged as nestable. When this flag is set, Locations of this type may nest within one another, similar to how Regions work at present. This allows you to have a variable-depth hierarchy of Locations, for example:

• Main Campus ("Building Group" location type)
  • West Campus (Building Group)
    • Building A ("Building" location type)
    • Building B (Building)
  • East Campus (Building Group)
    • Building C (Building)
    • Building D (Building)
  • South Campus (Building Group)
    • Western South Campus (Building Group)
      • Building G (Building)
• Satellite Campus (Building Group)
  • Building Z (Building)

In the above example, only two LocationTypes are defined ("Building Group" and "Building") but the "Building Group" type is flagged as nestable, so one Building Group may contain another Building Group.

Required Relationships (#873)

Relationships can be marked as being required. By default, relationships are not marked as being required.

To mark a relationship as being required, select "Source objects MUST implement this relationship" or conversely "
Destination objects MUST implement this relationship" from the "Required on" field when editing or creating a
relationship:

• If "Destination objects MUST implement this relationship" is selected, objects of the type selected in "Destination Type" will enforce this relationship when they are created or edited.
• If "Source objects MUST implement this relationship" is selected, objects of the type selected in "Source Type" will enforce this relationship when they are created or edited.

Changed

Database Query Caching is now Disabled by Default (#1721)

In prior versions of Nautobot, database query caching using the django-cacheops application (aka Cacheops) was enabled by default. This is determined by the default value of the CACHEOPS_ENABLED setting being set to True.

Through much trial and error we ultimately decided that this feature is more trouble than it is worth and we have begun to put more emphasis on improving performance of complex database queries over continuing to rely upon the various benefits and pitfalls of utilizing Cacheops.

As a result, the value of this setting now defaults to False, disabling database query caching entirely for new deployments. Cacheops will be removed entirely in a future release.

Users with existing nautobot_config.py files generated from earlier versions of Nautobot will still have CACHEOPS_ENABLED = True unless they modify or regenerate their configuration. If users no longer desire caching, please be sure to explicitly toggle the value of this setting to False and restart your Nautobot services.

Redesigned List Filtering UI (#1998)

Added a dynamic filter form that allows users to filter object tables/lists by any field and lookup expression combination supported by the corresponding FilterSet and API.
