That's what I had at the beginning, and it breaks.
This is a bit of a sad situation, as it breaks interoperability in simple
ways, but I will try the suggestion of reading without a model and then
writing with a model to do an update. I don't love it, as it makes the
code ugly and not
Again thanks for the suggestion. Using the low-level interface works
beautifully. I had to read the source code of appengine to figure out
wholly how to use it, but once that was done, I almost like the low-level
interface more than the high-level one. Entities behave like dictionaries
And here is some example code for getting and putting raw entities - ie no
model involved
from google.appengine.api import datastorefrom google.appengine.api import
datastore_errorsdef get_entities(keys):rpc = datastore.GetRpcFromKwargs({})
keys, multiple =
I tried to use both default=[] (which did not stop the error from
occurring), and required=False (which generated a new error, as the only
value allowed for required is True).
So it appears that the old solutions for this bug are not viable.
A mapreduce would cost a lot of money given the
Yes, and it did not work.
I cannot fix all the data, as the cost would be quite large.
This leaves giving up doing what I wanted to do in Python, or fetching the
underlying data without a model.

Thanks! This is a great suggestion; it might be the only one that works
(short of giving up doing what I wanted to do in Python).
The interesting thing is that the Java side has no trouble at all reading
those entities.

What about just dropping the required parameter from the property have you
tried that.

This is pretty bad!
As pointed out
in https://code.google.com/p/googleappengine/issues/detail?id=8962 , if you
add a StringListProperty to a model with existing entities in the
datastore, then you cannot read those entities any more!
Furthermore, in Java it is apparently possible to write

Hello,
I have a model with a single attribute that is a StringListProperty.
I get an error if I define it as such:
class Test(db.Expando):
people = db.StringListProperty(required=False, indexed=True)
However, on changing it
