python - How do I use get_or_insert in GAE? -

according documentation have pass in first key, , shall pass in properties initialise, model saved. of done in form of **kwargs.

the definition seems this:

def _get_or_insert(*args, **kwds): 

this way intended use it, yet throws exception:

record1, is_created = record.get_or_insert(record_key, {'record_date' : event1.date_time, 'user' : user.key}) 

the model defined as:

class record(ndb.model):     user = ndb.keyproperty(kind=user)     record_date = ndb.dateproperty(required=true) 

exception:

file "/applications/googleappenginelauncher.app/contents/resources/googleappengine-default.bundle/contents/resources/google_appengine/google/appengine/ext/ndb/model.py", line 3396, in _get_or_insert_async cls, name = args # these must positional. valueerror: many values unpack

any advice?

kwargs should passed key/value pairs. try like:

record1, is_created = record.get_or_insert(record_key, record_date = event1.date_time,  user = user.key)
