Testing code:

CODE ---------------------

#!/usr/bin/env

import requests
from blitzdb import Document, FileBackend


API_URL = 'http://api.themoviedb.org/3'
API_KEY = 'ddf3xxxxxxxx0289'


class Actor(Document):
    pass


def get_actor(_id):
    r = requests.get('{}/person/{}?api_key={}'.format(API_URL, str(_id),
API_KEY))
    return r.json()


actor_1 = Actor(get_actor(1))
actor_2 = Actor(get_actor(2))

backend = FileBackend("db.blitz")
actor_1.save(backend)
actor_2.save(backend)

print(backend.get(Actor,{'imdb_id' : 'nm0000184'}))
print('\n')
print(backend.get(Actor,{'imdb_id' : 'nm0000434'}))


OUTPUT ---------------------

Warning: cjson could not be imported, CJsonSerializer will not be available.
Traceback (most recent call last):
  File ".\uff.py", line 27, in <module>
    print(backend.get(Actor,{'imdb_id' : 'nm0000184'}))
  File "C:\Python34\lib\site-packages\blitzdb\backends\file\backend.py",
line 456, in get
    raise cls.DoesNotExist
blitzdb.document.DoesNotExist: DoesNotExist(Actor)


QUESTION ---------------------

Why the output says that Actor doesn't exists when I already added it here
'actor_1.save(backend)' and 'actor_2.save(backend)'
