Hi,
I am pretty new to google app engine and using the google datastore.
I have few files like
Destination, Trip, Answer, Question (see attached). Whenever the app engine
tries ti initialize the Trip object, I am getting the error below. Please
help.
File "C:\ujjal\my project\cravel\code2\Trip.py", line 7, in <module>
class Trip(ndb.Model):
File "C:\ujjal\my project\cravel\code2\Trip.py", line 10, in Trip
destinations = ndb.StructuredProperty(Destination1, repeated = True)
File "C:\Program
Files\Google\google_appengine\google\appengine\ext\ndb\utils.
py", line 136, in positional_wrapper
return wrapped(*args, **kwds)
File "C:\Program
Files\Google\google_appengine\google\appengine\ext\ndb\model.
py", line 1993, in __init__
if modelclass._has_repeated:
AttributeError: 'module' object has no attribute '_has_repeated'
