google app engine - how can i add multiple references to a blob object in a ndb model for gae -


how can add multiple references blob object in ndb model gae

following not work. 

blob_keys = blobstore.blobreferenceproperty(repeated=true)

typeerror: init() got unexpected keyword argument 'repeated'

this not work

blob_keys= ndb.listproperty(blobstore.blobkey)

if you're using ndb, should using ndb version of blobstore reference.

blob_keys = ndb.blobkeyproperty(repeated=true)

listproperty isn't ndb either. make sure you're looking @ correct documentation. https://developers.google.com/appengine/docs/python/ndb/properties#types
