Python Google endpoints_proto_datastore list data

I am trying to create some endpoints for my app engine application using endpoints_proto_datastore it works because the urls return something but just not what I expected.

Here is the code I have I know some of the imports are not needed but they are temporary

Model File

import endpoints
from google.appengine.ext import db
import webapp2
from endpoints_proto_datastore.ndb import EndpointsModel

class Estate(EndpointsModel):
    hicid = db.IntegerProperty()
    name = db.StringProperty()
    address= db.PostalAddressProperty()
    contact_phone = db.PhoneNumberProperty()
    contact_name = db.StringProperty()
    contact_email = db.EmailProperty()
    location = db.GeoPtProperty()
    created = db.DateTimeProperty(auto_now_add=True)
    updated = db.DateTimeProperty(auto_now=True)

API file

import endpoints
from google.appengine.ext import ndb
from protorpc import remote

from endpoints_proto_datastore.ndb import EndpointsModel
from models.estate import *

@endpoints.api(name = 'raceManagerAPI', version = 'v1', description = 'An api for access to important data')
class raceManagerAPI(remote.Service):

    @Estate.query_method(path = 'estates', name = 'estate.list')
    def EstateList(self, query):
        return query

app.yaml file

application: yellow-fox
version: 1
runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: /assets
  static_dir: assets

- url: /signup
  script: main.app
  secure: always

- url: /login
  script: main.app
  secure: always

- url: /forgot
  script: main.app
  secure: always

# Endpoints Api
- url: /_ah/spi/.*
  script: main.application

- url: .*
  script: main.app

libraries:
- name: webapp2
  version: "2.5.1"
- name: jinja2
  version: latest
- name: endpoints
  version: latest

main.py file has this in

application = endpoints.api_server([raceManagerAPI], restricted=False)

and this is what I get back from the api explorer

{
 "kind": "raceManagerAPI#estateItem",
 "etag": "\"hx0GGGqNWMq76QilvaW15fvq6DI/taVVBKufuJZtJ6w1S7kF6sHCh4M\""
}

What i was expecting was a list of items can someone tell me where I am going wrong the documentation don't give me much of an idea.

I believe your problem comes from using the old style db here:

from google.appengine.ext import db

and in the various properties of Estate, such as:

name = db.StringProperty()

Rather, you must use the new style ndb, changing those two lines respectively to:

from google.appengine.ext import ndb

and:

name = ndb.StringProperty()

Now, in ndb you won't find PostalAddressProperty &c, so you'll need to fix those. But, the general idea is: always ever use ndb, not db.
