class AddressSerializer(serializers.ModelSerializer):
depth = 3
class Meta:
model = Address
fields = ['id', 'building_no', 'street', 'locality',
'landmark', 'pincode', 'latitude', 'longitude', 'city']
class DisplayAddressSerializer(AddressSerializer):
depth = 1
Now you can add display_address to any serializer using an address and API
consumers can use it to render easily. You can then use AddressSerializer to
provide
the full structured address, so it can be used for writes.
You may need to customize how it flattens the models, but that's what DRF's
documentation[1] is for.
