get_by_id issue?

[gwstuff]

Hi,

I am having trouble getting get_by_id working on the latest version of dev_appserver. Is anyone else facing this issue with the latest release?

Input (on the interactive console):

from db.note import Note

n = Note.all()[0]

i = n.key().id()

print i

print Note.get_by_id(i)

Output:

3

None

Strange, your code works fine for me. This also works for me:

class Test(db.Model):
pass

t_key = Test().put()
t_id = t_key.id()
print type(t_id), t_id

t = Test.get_by_id(t_id)
print str(t.key())

do it has a parent entity which makes get_by_id failed?

Yes, that was it. I realized it while debugging my problem further the next day. I was wrongly assuming that ids are unique - they are in fact only unique given the path of the parent entity. For my purpose, using a full key is more appropriate.
