AttributeError: object has no attribute 'extent'

[hemache]

Hello,

GeoFeatureModelSerializer fails to get bounding box when geo_field points to a SerializerMethodField

AttributeError: object has no attribute 'extent'

Example:

class PlaceSerializer(GeoFeatureModelSerializer):
    location = GeometrySerializerMethodField()

    class Meta:
        model = Location
        fields = ["name"]
        id_field = "pk"
        geo_field = "location"
        auto_bbox = True

    def get_location(self, obj):
        return obj.location.transform(4326, clone=True)
