Assigning Tenant to a DCIM Site.

[coujin11]

Hey Guys,

Im currently trying to write a script with Pynetbox which will allow me to assign an existing tenant and group to a DCIM Site.

However, I am running into a few issues, where pynetbox interprets it as creating a new tenant and now assigning an existing one.

As a test this is what i am using:
import pynetbox

# NetBox API details
NETBOX_URL = 
NETBOX_TOKEN = 

# Initialize Pynetbox API
nb = pynetbox.api(NETBOX_URL, token=NETBOX_TOKEN)

# Site and Tenant IDs
SITE_ID = 23803
TENANT_ID = 24145

# Fetch the Site object
site = nb.dcim.sites.get(id=SITE_ID)
if not site:
    print(f"Error: Site with ID {SITE_ID} not found.")
    exit()

# Fetch the Tenant object
tenant = nb.tenancy.tenants.get(id=TENANT_ID)
if not tenant:
    print(f"Error: Tenant with ID {TENANT_ID} not found.")
    exit()

# Fetch the Tenant Group object
if hasattr(tenant, "group") and tenant.group:
    tenant_group = tenant.group
else:
    print(f"Error: Tenant '{tenant.name}' has no assigned group.")
    exit()

print(f"Found Site: {site.name} (ID: {SITE_ID})")
print(f"Found Tenant: {tenant.name} (ID: {TENANT_ID})")
print(f"Found Tenant Group: {tenant_group.name} (ID: {tenant_group.id})")

# Prepare the update payload
payload = {
    "tenant": {
        "id": tenant.id,
        "name": tenant.name,
        "slug": tenant.slug,
        "group": {
            "id": tenant_group.id,
            "name": tenant_group.name,
            "slug": tenant_group.slug
        }
    }
}

# Send PATCH request to update the site
try:
    updated_site = site.update(payload)
    if updated_site:
        print(f"Successfully assigned Tenant '{tenant.name}' to Site '{site.name}'.")
    else:
        print(f"Failed to update the Site with Tenant.")
except pynetbox.RequestError as e:
    print(f"API Error: {e.error}")

Results:
Found Site: 20:20 House Residential Management - 20:20 House - Leeds (ID: 23803)
Found Tenant: 20:20 House Residential Management - 20:20 House - Leeds (ID: 24145)
Found Tenant Group: 20:20 Leeds (ID: 2643)
API Error: {"tenant":{"non_field_errors":["The fields group, name must make a unique set.","The fields group, slug must make a unique set."]}}

The above this the code I am working with. It would be appreciated if anyone cant advise if I am doing something wrong or if this is a possible bug?
