nbforager

Overview

Python package designed to help work with the Netbox_ REST API.

• NbApi_ Request data from Netbox using filter parameters identical to those in the Web UI filter form. Filter parameters use the OR operator.
• NbForager_ The REST API returns objects that contain a brief representation of related objects. NbForager replaces brief data with full and objects look like a recursive multidimensional dictionary.
• NbParser_ Extract typed values from a Netbox object dictionary by using a chain of keys.

Versions

• nbforager <1 is designed for Netbox v3 (checked with Python >= v3.8, Netbox v3.5.4)
• nbforager >=1,<2 is designed for Netbox >=v4.2 (checked with Python >= v3.8, Netbox v4.3.3)
• Netbox >=v4.0,<=4.1 is not tested.

Fully documented on Read the Docs_.

Requirements

Python >=3.8

Quickstart

Install the package from pypi.org

.. code:: bash

pip install nbforager

or from github.com repository

.. code:: bash

pip install git+https://github.com/vladimirs-git/nbforager

NbForager demonstration. Assemble Netbox objects within self as a multidimensional dictionary.

Request the main object. All nested objects also are requested. Assemble multidimensional dictionary.

.. code:: python

from pprint import pprint

from nbforager import NbForager

HOST = "demo.netbox.dev"
TOKEN = "1234567890123456789012345678901234567890"
nbf = NbForager(host=HOST, token=TOKEN, threads=10)

# Request devices with all nested object: device-roles, tenants, tags, etc.
nbf.dcim.devices.get(nested=True)
print(f"{len(nbf.root.dcim.devices)=}")
print(f"{len(nbf.root.dcim.device_roles)=}")
print(f"{len(nbf.root.tenancy.tenants)=}")
print(f"{len(nbf.root.extras.tags)=}")
# len(nbf.root.dcim.devices)=78
# len(nbf.root.dcim.device_roles)=10
# len(nbf.root.tenancy.tenants)=5
# len(nbf.root.extras.tags)=2


# Assemble objects within self as multidimensional dictionary.
tree = nbf.join_tree()
pprint(list(tree.dcim.devices.values())[0])
# {"id": 1,
#  "name": "dmi01-akron-rtr01",
#  "rack": {"id": 1,
#           "site": {"id": 2,
