Tags in Custom Script

[wz4]

On a custom script form, I would like to show tags only related to the Device model. I have been unsuccessful so far finding the right query params. I believe it should be similar to the following, but error is "Object of type ConfigContextModelQuerySet is not JSON serializable." Any advice?

    tags = MultiObjectVar(
        label='Tags',
        model=Tag,
        required=False,
        query_params={
            'object_types': Device.pk
        },
    )

Untested, but try something like this:

        query_params={
            'object_types': [ContentType.objects.get_for_model(Device).pk]
        },

or

        query_params={
            'object_types': [ContentType.objects.get(app_label='dcim', model='device').pk]
        },

I got this from the Netbox source code:

    def test_object_types(self):
        object_types = ContentType.objects.filter(model__in=['site', 'rack'])
        params = {'object_types': [object_types[0].pk, object_types[1].pk]}
        self.assertEqual(self.filterset(params, self.queryset).qs.count(), 2)

and

        object_types = (
            ContentType.objects.get(app_label='dcim', model='site'),
            ContentType.objects.get(app_label='dcim', model='rack'),
            ContentType.objects.get(app_label='dcim', model='device'),
        )

Thank you, your first suggestion works. I also found a builtin filter that does effectively the same thing.

That narrows the list by object_type, but eliminates tags that don't have any object_type set. Ideally, I would see both.

That looks like a Jinja2 template filter: {{ foo | content_type_id }}

If you want a way via the API to filter "tags which are applicable to content type X (including those which are applicable to any content type)" then you can raise it as a feature request.

I appreciate the response. I think explicit tag assignments makes more sense for my use case anyway.
