Django integer fields gets transformed to Float?

On a project of mine I noticed this unexpected behavior:

Using graphene_django with graphene.relay converts IntegrierFields of my models to graphene.Float properties in the API, e.g.:

class Incident(models.Model):
    incident_id = models.IntegerField(unique=True)

class IncidentType(graphene_django.types.DjangoObjectType):
    class Meta:
        model = Incident
        interfaces = (graphene.relay.Node,)
        filter_fields = {
            'incident_id': ['exact'],
    }

class Query:
    incident = graphene.relay.Node.Field(IncidentType)
    incidents = DjangoFilterConnectionField(IncidentType)

To be precise, using the incident attribute shows the incidentId to be of type Int. But using the incidents attribute suggests that incidentId is of type Float.

I’d like to point out, that there is no error occurring, but it strikes me as weird.

I observed this with:

• Django 2.2
• django-filter 2.1.0
• graphene 2.1.3
• graphene-django 2.2.0
• graphql-core 2.1
• graphql-relay 0.4.5

Same problem as @Gamsake here, with 2.15.0. The problem seems to occur when using filter_fields on a django model’s id column.

Our workaround is to define and set an explicit filterset class:

class Country(models.Model):
    name = models.CharField(max_length=255, unique=True)


class CountryFilter(django_filters.FilterSet):
    id = django_filters.ModelChoiceFilter(queryset=Country.objects.all().values_list("id", flat=True))

    class Meta:
        model = Country
        fields = {
            "id": ["exact"],
            "name": ["exact"],
        }


class CountryType(DjangoObjectType):
    # ...

    class Meta:
        model = Country
        # filter_fields = ["id", "name"]
        filterset_class = CountryFilter

@jkimbo Yes. I’m using 2.4.0 the latest now and ‘id’ the field of my model has Int type, but it is converted into Float type. Exactly same issue as above first post. I’ve done triple checks but i never solve this problem. any clue plz.
