GraphQL Device Query - Role filter issue

[jathanism]

In this particular case, it appears that the devices.role filter is filtering on the Device.device_role.slug field and not the name field:

To illustrate this, I attempted a filter on Backbone and got the unfiltered results, which IMO is not the expected behavior if the filter parameter is incorrect. You'd think it would return no matches instead of all?

Query on Backbone:

{
  devices(role: "Backbone"){
    id
    name
    device_role {
      name
      slug
    }
  }
}

Result (first item only):

{
  "data": {
    "devices": [
      {
        "id": "60833d08-7bdd-4b40-a8c4-33c1984ccc90",
        "name": "ams-edge-01",
        "device_role": {
          "name": "edge",
          "slug": "edge"
        }
      },

Then I did it with backbone:

{
  devices(role: "backbone"){
    id
    name
    device_role {
      name
      slug
    }
  }
}

With this result, matching your expected results:

{
  "data": {
    "devices": [
      {
        "id": "7b871f65-d4d5-4ab5-8fd5-211a8e093976",
        "name": "jcy-bb-01.infra.ntc.com",
        "device_role": {
          "name": "Backbone",
          "slug": "backbone"
        }
      },
      {
        "id": "bfcd2323-5b32-4388-af61-05a7ed1404f7",
        "name": "nyc-bb-01.infra.ntc.com",
        "device_role": {
          "name": "Backbone",
          "slug": "backbone"
        }
      }
    ]
  }
}

Can you please confirm?

I can confirm the same.

If the filters are coming from here.
Upon further research based on your comment, it seems that this might be a known issue with MultipleChoice Filter where filtering is becoming a NOOP due to no choice being present (assuming incorrect filter choice == no filter). This is based on this documentation of the filter.
