Deployment Type

Self-hosted

NetBox Version

v4.0.0

Python Version

3.10

Steps to Reproduce

Create a tenant named "Test Tenant". Make a note of the tenant's id (in my case it's 7)
Create a site using REST API

curl -s -X POST \
-H "Authorization: Token 0123456789abcdef0123456789abcdef01234567" \
-H "Content-Type: application/json" \
http://localhost:32768/api/dcim/sites/ \
--data '{"name": "Test site 1", "slug": "test-site-1", "tenant": 7}' | jq '.'

Expected Behavior

The site is created in and tenant is set to Test tenant.

Observed Behavior

{
  "tenant": {
    "non_field_errors": [
      "Invalid data. Expected a dictionary, but got int."
    ]
  }
}

The same API calls work as expected in NetBox 3.7.

I see the issue with SiteSerializer; we're not passing nested=True to TenantSerializer. Easy fix.

@rodvand have you come across this issue for any other models? A quick check suggests it affects only the site model, but I'll do a more thorough audit.
