Geojson serializer decorator for django rest framework

DRF geojson serializer is a decorator which allows to format data as geojson http://geojson.org

Quick start

Geojson serializer works with django rest framework as a decorator.

1. Add django-geojson_serializer to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
   ....
   'geojson_serializer'
   ]
   

2. In your code you can use geojson_serializer(<name-of-geo-field>) decorator with a regualar serializer, e.g.:

   from geojson_serializer.serializers import geojson_serializer
   
   
   class City(models.Model):
       name = models.CharField(max_length=128)
       location = models.PointField()
   
   
   @geojson_serializer('location')
   class CitySerializer(serializers.ModelSerializer):
       class Meta:
           model = City
           fields =['name', 'location']
   
   
   class CityViewSet(viewsets.ModelViewSet):
       queryset = City.objects.all()
       serializer_class = CitySerializer
   

   Then you can register CityViewSet with a router and the view will generate and accept geojsons in corresponding requests.

3. Also supported are id and bbox fields:

   @geojson_serializer('location', id='id', bbox='bounding_box')
   class MySerializer(serializers.ModelSerializer):
   ....
   

   In this case 'id' and 'bounding_box' fields should be defined by the underlying serializer MySerializer.
