# For address model
class AddressResource(ModelResource):
  street_name = fields.CharField()
  suburb = fields.CharField() 

# For organization model
class OrganizationResource(ModelResource):
  address = fields.ToOneField(AddressResource, 'address')

# Now when you get /api/v1/organization
# in the JSON that is returned, each organization
# will also have the address for the address 
# that is related to it.
