KeyProperty and repeated=True

[Owen Nelson]

Hi, I'm working with the new datastore plus API, and I'm getting a stack trace when I create a model with a repeated KeyProperty. Is this expected?

The error the trace ends with is:

TypeError: argument of type 'MetaModel' is not iterable

I'm specifying the property like:

class MyModel(model.Model):

    bars = model.KeyProperty(Bar, repeated=True)

Ok, I think I see where the disconnect is.
KeyProperty only accepts instances of model.Key (which is fair). If I want to limit my property on my model to only accept certain kinds of keys, I should enforce this requirement through a validator.

Unless there's a better way, I think I'm all set!
