Unable to retrieve interface and connection information

[KohnaiK]

Problem description:
When I try to retrieve information about the connected device via the interfaces tagged "NINJA", I cannot get detailed information about device B (the connected device).

Steps to reproduce:

1. Use the Python script with the filter to retrieve the "NINJA" tagged interfaces.
2. For each interface retrieved, attempt to retrieve detailed information about the connected device (device B).

Current behavior:
I manage to retrieve the interfaces tagged "NINJA", but when I try to retrieve the details of the connected device, I don't get the desired information or i have a bug (i changed my script like, 40~50 times and still doesn't work, with pynetbox, netbox-python...).

Expected behavior:
I expect to be able to successfully retrieve the details of the connected device via the "NINJA" tagged interfaces.
For example :
Device name A; Interface name A source ---> Device name B; Interface name B destination

import pynetbox
import requests 
import warnings

# Ignorer les avertissements liés à la vérification SSL non sécurisée
warnings.filterwarnings("ignore", category=requests.packages.urllib3.exceptions.InsecureRequestWarning)

# session requests avec la vérification SSL désactivée
session = requests.Session()
session.verify = False

# Initialiser l'API NetBox sans spécifier http_session
nb = pynetbox.api(
    url="...",  
    token="...",  
)

nb.http_session = session

# Terme du tag "NINJA"
ninja_tag_term = "ninja"

# Fonction pour afficher les informations des appareils avec le tag "NINJA" et les détails de la connexion
def display_ninja_devices_with_connections(tag_term):
    if tag_term is not None:
        devices = nb.dcim.devices.filter(tag=tag_term)
        print(f"Appareils avec le tag '{tag_term}':")
        for device in devices:
            print(f"\n{device.name}:")
            interfaces = device.interfaces.all()
            for interface in interfaces:
                print(f"  Interface {interface.name} (A side):")
                if interface.connected_endpoint:
                    connected_device = interface.connected_endpoint.device
                    connected_interface = interface.connected_endpoint.interface
                    print(f"    Connecté à {connected_device.name} (B side), Interface {connected_interface.name}")
                else:
                    print("    Pas de connexion")

# Afficher les informations pour tous les appareils avec le tag "NINJA" et les détails de la connexion
display_ninja_devices_with_connections(ninja_tag_term) `

Actually i have this problem :

I accept any advice, thanks.

    devices = nb.dcim.devices.filter(tag=tag_term)
    for device in devices:
        interfaces = nb.dcim.interfaces.filter(device_id=device.id)
        for interface in interfaces:
             print(device.name, interface.name)

Hi, your code works, it shows me the interfaces of all my tagged devices. But it's not exactly what I want, for example I would have liked:

Firewall_test : ethernet1/8 connected at Switch_Test : TenGigabitEthernet1/0/22

I updated my script but it still doesn't works :

import pynetbox
import requests
import warnings

# Ignorer les avertissements liés à la vérification SSL non sécurisée
warnings.filterwarnings("ignore", category=requests.packages.urllib3.exceptions.InsecureRequestWarning)

# Session requests avec la vérification SSL désactivée
session = requests.Session()
session.verify = False

# Initialiser l'API NetBox sans spécifier http_session
nb = pynetbox.api(
    url="<urlnetbox>", 
    token="<tokennetbox>", 

nb.http_session = session

# Terme du tag "NINJA"
ninja_tag_term = "ninja"

# Fonction pour récupérer les appareils avec le tag "NINJA" et des interfaces
def get_ninja_devices_with_interfaces(tag_term):
    ninja_devices = []
    if tag_term is not None:
        devices = nb.dcim.devices.filter(tag=tag_term)
        for device in devices:
            ninja_devices.append(device)
    return ninja_devices

# Récupérer les appareils avec le tag "NINJA" et des interfaces
ninja_devices_with_interfaces = get_ninja_devices_with_interfaces(ninja_tag_term)

# Afficher les noms des appareils avec des interfaces
if ninja_devices_with_interfaces:
    print(f"Appareils avec le tag '{ninja_tag_term}' et des interfaces:")
    for device in ninja_devices_with_interfaces:
        print(f"  {device.name}")

    # Récupérer toutes les interfaces
    all_interfaces = nb.dcim.interfaces.all()

    # Filtrer les interfaces qui appartiennent aux appareils taggés "NINJA"
    ninja_interfaces = [interface for interface in all_interfaces if interface.device in ninja_devices_with_interfaces]

    # Afficher les interfaces pour chaque appareil
    for interface in ninja_interfaces:
        print(f"\nInterfaces pour {interface.device.name} - {interface.name} (A side):")
        if interface.connected_endpoints:
            for connection in interface.connected_endpoints:
                other_interface = connection.interface_a if connection.interface_b.id == interface.id else connection.interface_b
                print(f"  Connecté à {other_interface.device.name} - {other_interface.name} (B side)")
        else:
            print("  Pas de connexion")
else:
    print(f"Aucun appareil trouvé avec le tag '{ninja_tag_term}' et des interfaces")
