Plugin DynamicModelChoiceField Filtering

[cslingerland]

As I understand it, the DynamicModelChoiceField ties into the API to get results and build the list, but I'm not able to get this to work for the models in my Plugin. I have the base API setup and working but when I use this field class, I get no results. I have a workaround of using django.forms.ModelChoiceField, but it'd be nice if I could get DynamicModelChoiceField working.

Interestingly, when I edit an existing Relationship, the form does show the Vendor correctly, but it just has the one listed. It doesn't fetch any other results so I can't change the vendor.

Here's my form class:

class RelationshipForm(NetBoxModelForm):
    vendor = DynamicModelChoiceField(
        queryset=Vendor.objects.all(),
        required=False,
    )
    
    class Meta:
        model = Relationship
        fields = ('vendor', 'dc', 'notes', 'tags',)

If you open up your dev-tools after loading the page, what does it try to connect to after you open the choice field? There should be a API query, that might give you some insight.

It populates correctly when it is edited with an existing one because the data is pre-populated with that vendor.

Hi ,
I am seeing a similar issue with my SecretRoleSerializer(ValidatedModelSerializer). When trying to filter using SecretRole.

class SecretRoleSerializer(ValidatedModelSerializer):
    url = serializers.HyperlinkedIdentityField(view_name='*********')
    secret_count = serializers.IntegerField(read_only=True)

    class Meta:
        model = SecretRole
        fields = ['id', 'url', 'name', 'slug', 'description', 'secret_count']

and my secretRole model has the str method mapping to name which is included in the fields.

Can someone help me with this please

You are missing display field. Check https://github.com/Onemind-Services-LLC/netbox-secrets/blob/master/netbox_secrets/api/serializers.py#L58
