# Serialize NDB Model(s) to a JSON string.
json_str = ndb_json.dumps(models)

# Parse a JSON string into a Python dictionary.
ndb_json.loads(json_str)When the encoder meets a property of thendb.Keytype,
there are three encoding options available:ndb_keys_as_entities- encode Key property as aFuturewhose eventual result is the entity for the key. (default)ndb_keys_as_pairs- encode Key property as a tuple of (kind, id) pairs.ndb_keys_as_urlsafe- encode Key property as a websafe-base64-encoded serialized version of the key.Please refer toNDB Key Classdocumentation for details.For example, for the following data models:class Master(ndb.Model):
      name = ndb.StringProperty()class Details(ndb.Model):
      master = ndb.KeyProperty()
      description = ndb.StringProperty()and following records:master = Master(id=123456L, name='Europe')
    details = Details(
      master=ndb.Key(Master, 123456L), 
      description='List of European customers'
     )The callsjson_str = ndb_json.dumps(details)
    json_str = ndb_json.dumps(details, ndb_keys_as_entities=True)will return{"master": {"name": "Europe"}, "description": "List of European customers"}The calljson_str = ndb_json.dumps(details, ndb_keys_as_pairs=True)will return{"master": [["Master", 123456]], "description": "List of European customers"}The calljson_str = ndb_json.dumps(details, ndb_keys_as_urlsafe=True)will return{"master": "agFfcg4LEgZNYXN0ZXIYwMQHDA", "description": "List of European customers"}Feature parity with the Pythonjsonmodule functions.ndb_json.dumpsndb_json.dumpndb_json.loadsEnvironment moduleenviron.get_dot_target_name(version=None, module=None)Returns the current version/module in-dot-notation which is used bytarget:parameters.environ.get_dot_target_name_safe(version=None, module=None)Same asenviron.get_dot_target_name, but this function returnsNoneif there is no version or module found.environ.get_environ_dict()Return a dictionary of all environment keys/values.environ.is_host_google()True if the app is being hosted from Google App Engine servers.environ.is_development()True if the dev_appserver is running (localhost or local development server).environ.is_staging(version=None)True if the app is hosted by Google (appspot.com) but the version is not the default.environ.is_staging_safe(version=None)Same asenviron.is_staging, but returnsNoneif there is no version found.environ.is_production(version=None)True if the app is being hosted by Google and the default version.environ.is_production_safe(version=None)Same asenviron.is_production, but returnsNoneif there is no version found.environ.is_default_version(version=None)True if the current or specified app version is the default.environ.is_default_version_safe(version=None)Same asenviron.is_default_version, but returnsNoneif there is no version found.environ.get_current_version_name_safe()Wrapper aroundgoogle.appengine.api.modules.get_current_version_name.
