While this issue is systematic, I'll provide an example using domains and subnets to illustrate the problem.

As an admin:
1. Create a new domain: "example.org"
2. Create a User: "testuser"
3. Create a new Role: "Subnets Role"
4. Add a Filter to the Role with - Type: Subnets, Permissions: create_subnets, view_subnets

As testuser:

curl -u testuser:testuser -X POST -d '{"name": "subnet1", "network": "255.168.192.1", "mask": "255.255.255.0", "domains": [{"id": 1}]}' -H "Content-Type: application/json" http://10.13.129.41:3000/api/v2/subnets
