nautobot-function-codes 0.1.0

A Nautobot plugin for managing reusable Function Codes.

Nautobot Function Codes

A Nautobot plugin for managing reusable Function Codes and assigning them to devices.

Documentation: docs.nautobot.com/projects/function-codes

Features

Function Codes

• Create and manage Function Codes (name, slug, description, is_active)
• REST API and GraphQL support
• Global and list search, filtering, and CSV import/export
• Object permissions, changelog, notes, custom fields, relationships, custom links, and webhooks

Device assignments

• One Function Code per device (via DeviceFunctionCodeAssignment)
• Assign devices in bulk from Function Code detail or Device Assignments
• Device Assignments list with view, edit, bulk edit, and delete
• Clear assignments in bulk from the plugin menu
• Function Code column on the Device list
• Editable Function Code panel on Device detail pages
• Validation prevents assigning inactive Function Codes

Coverage and import

• Coverage dashboard with assignment statistics by Function Code, status, location, and role
• Links to unassigned devices and assignments that reference inactive Function Codes
• Synchronous CSV import/export from Function Codes → Import Assignments (no Celery required)
• Nautobot Jobs for scheduled or background audit and CSV import (requires Celery worker)

Filtering

• Filter Device list by Function Code
• Filter Device list by whether a device has a Function Code assigned (Has Function Code)

Requirements

• Nautobot 3.1.0 or higher
• Python 3.12 or higher

Installation

Install the package from PyPI:

pip install nautobot-function-codes

Add the plugin to your Nautobot configuration:

PLUGINS = ["nautobot_function_codes"]

Run database migrations:

nautobot-server migrate nautobot_function_codes

Restart Nautobot after installing and migrating the plugin.

Compatibility

Nautobot	Plugin	Python
3.1.x	0.1.x	3.12+

Development

This project uses the cookiecutter-nautobot-app development environment.

poetry install
invoke makemigrations
invoke start
invoke unittest

Other useful commands:

invoke pylint
invoke ruff
poetry run mkdocs build --no-directory-urls --strict
poetry run python -m build
poetry run python -m twine check dist/*

For local invoke commands that should run outside Docker, set:

export INVOKE_NAUTOBOT_FUNCTION_CODES_LOCAL=True

Releasing

Releases are published to PyPI automatically when a Git tag matching v* is pushed.

1. Update the version in pyproject.toml, for example:

   poetry version patch
   

2. Update release notes or changelog content as needed.

3. Commit the release changes:

   git add pyproject.toml poetry.lock CHANGELOG.md docs/admin/release_notes
   git commit -m "Prepare release vX.Y.Z"
   

4. Create and push the tag:

   git tag vX.Y.Z
   git push origin vX.Y.Z
   

The Release GitHub Actions workflow builds the package with python -m build, verifies it with twine check, and publishes it to PyPI. If PyPI Trusted Publishing is configured for this repository and workflow, no API token is needed. Otherwise, add a repository or environment secret named PYPI_API_TOKEN containing a PyPI API token.

Managing Device Assignments

Device assignments are managed from the Function Codes plugin menu:

1. Function Codes → Function Codes — create and manage Function Code records
2. Function Code detail → Assign Devices — assign many devices to one Function Code
3. Function Codes → Device Assignments → Add — bulk form with Function Code and Devices fields
4. Function Codes → Device Assignments — list, edit, bulk edit, and delete assignments
5. Function Code detail → Assigned Devices — view devices linked to a Function Code
6. Device detail → Function Code — view or update the assignment for a single device
7. Function Codes → Coverage — review assignment coverage and open unassigned or inactive assignments
8. Function Codes → Import Assignments — upload, validate, or export assignment CSV files
9. Function Codes → Clear Assignments — clear assignments for selected devices

REST API

Endpoint	Description
/api/plugins/function-codes/function-codes/	Function Code CRUD
/api/plugins/function-codes/device-assignments/	Device assignment CRUD

Device list filtering examples:

• ?nautobot_function_codes_function_code=acc — devices with Function Code slug acc
• ?nautobot_function_codes_has_function_code=true — devices with any Function Code assigned
• ?nautobot_function_codes_has_function_code=false — devices without a Function Code

CSV import format

Required columns:

device,function_code
switch-01,acc
switch-02,

Use the device name or UUID. Leave function_code empty to clear an assignment. Inactive Function Codes are rejected.

The same format is used by both Import Assignments (UI) and the Import Function Code Assignments job. The import UI can also download a blank CSV template or export the current assignment state.

Jobs

The plugin registers two Nautobot Jobs:

• Audit Function Code Assignments — report unassigned devices and assignments to inactive Function Codes
• Import Function Code Assignments — import assignments from CSV via the job engine

Jobs require a running Celery worker. The Coverage dashboard and Import Assignments UI work without Celery.

Run diagnostics after deployment:

nautobot-server diagnose_nautobot_function_codes

Tags

Function Codes use Nautobot's OrganizationalModel base class (similar to Roles and Platforms). Tags are supported on Device objects, not on Function Code records.
