Hi All,

im getting confused with the usage of dynamic inventories with netbox.

I had a playbook which is execute on server with a specific role:  
ex:

```auto
- name: server_monit
  hosts: device_roles_server_monit
  roles:
    - role: role0
      tags: [role0]
    - role: role1
    - role: role2
      when: is_role_2 is defined

```

The variable is\_role\_2 is defined in tags\_role\_2 file in group\_vars and there is a device\_roles\_server\_monit in groups\_vars as well.

But when i tag my server with role\_2 in netbox, ansible didnt run the playbook and output an empty inventory. it didnt take in count the device\_roles.

i tought there were a precedence with device\_role before tags variable and just merge variable if both are retrieve from netbox.

Where im wrong ?
