Unable to retrieve interface and connection information with API

[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 that i tried :

   1. GET devices with tag

   2. For device in devices, if device.interfaces is true, append to [device_list]

   3. GET dcim.interfaces?device_id=[device_list]

   4. For interface in interfaces, do something with interface.connected_endpoints
   

I currently have a lot of problems with step 4.

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

There is my script :

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="https://<ip>",  # Remplacez par votre URL NetBox
    token="<token>",  # Remplacez par votre jeton d'API NetBox
)

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")

I tried with graphviz too, but i have the same problem, i can't see the links between devices
