Problems with distance_Lte Filter

[fabian-ws]

Hello,

I want to use the distance_Lte filter as in the readme-file described. But I can´t perform the query. Can you tell me what my failure is?

My django classes:

class Location(models.Model):
    calendar = models.ForeignKey(Calendar, on_delete=models.CASCADE)
    name = models.CharField(max_length=255)
    location = models.PointField(srid=4326, unique=True)
    address = models.CharField(max_length=100)
    city = models.CharField(max_length=50)

class LocationType(GeoJSONType):
    class Meta:
        model = Location
        geojson_field = 'location'
        filterset_class = LocationFilter
        interfaces = (relay.Node,)
        exclude = []

class LocationFilter(GeometryFilterSet):
    class Meta:
        model = Location
        fields = {
            'city': ['exact', 'icontains', 'istartswith'],
            'location': ['exact', 'intersects', 'distance_lte']
        }

class Query(graphene.ObjectType):
    location = relay.Node.Field(LocationType)
    locations = DjangoFilterConnectionField(LocationType)

My graphql-Query:

query{
  locations(location_DistanceLte:{geometry:"{'type': 'Point', 'coordinates': [13.28702,52.4581]}", value:400, unit:"km"}){
    edges{
      node {
        id
      }
    }
  }
}

The error-msg:

{
  "errors": [
    {
      "message": "Argument \"location_DistanceLte\" has invalid value {geometry: \"{'type': 'Point', 'coordinates': [13.28702,52.4581]}\", value: 400, unit: \"km\"}.\nExpected type \"Geometry\", found {Geometry: \"{'type': 'Point', 'coordinates': [13.28702,52.4581]}\", value: 400, unit: \"km\"}.",
      "locations": [
        {
          "line": 2,
          "column": 34
        }
      ]
    }
  ]
}

I don´t know, what I´m doing wrong... It would be nice if you can help.

Thanks

Did you ever figure this out? I’m running into the same issue.

Same problem here

This problem is related with graphene object type. distance_lte require Distance type, but mapping type is Geometry.

from graphql_geojson.filters import GeometryFilterSet, DistanceFilter


class PlaceFilter(GeometryFilterSet):
    location__distance_lte = DistanceFilter(field_name='location', lookup_expr='distance_lte')

    class Meta:
        model = models.Place
        fields = {
            'name': ['exact']
        }
