Is it possible to filter on the other model attributes(properties in geojson) than geometry when using a GeoFeatureModelSerializer?

Hi Joakim,

I haven't understood your question.

Could you provide some context and show some code samples for your situation please?

Thanks for the reply and the great application!

My issues was regarding filtering in views on models using the GeoFeatureModelSerializer. I thought I had to access the attributes like this: properties.attr, or something like that.

class WorkOrderFilter(filterset.GeoFilterSet):
    products = UUIDFilter(name='products__product_id', lookup_type='exact')
    contains_geom = GeometryFilter(name='footprint', lookup_type='contains')
    projects = NumberFilter(name='projects__project_uuid', lookup_type='exact')

    class Meta:
        model = WorkOrder
        fields = ['products', 'contains_geom']


class WorkOrderViewSet(viewsets.ModelViewSet):
    queryset = WorkOrder.objects.all()
    serializer_class = WorkOrderSerializer
    bbox_filter_field = 'footprint'
    filter_backends = (filters.DjangoFilterBackend, InBBoxFilter)
    bbox_filter_include_overlapping = True
    filter_class = WorkOrderFilter
    filter_fields = ['products', 'contains_geom']

So here products is a list of UUID's under properties, following the GeoJSON spec. I got this to work.

Additional question:

Is it possible to use the Browsable API search Form with the GeoFeatureModelSerializer ?

Great news!

I have never done this yet and I don't know if anyone has done it, BUT
you could try to ask on stackoverflow.com, (be sure to include the
django-rest-framework tag) this way you should be able to get more
visibility to your question.

If we find a nice solution we could even add a few lines about this in
the documentation.
