Question

I\'m having a problem and I don\'t find any information about.

I define a field in my model like this.

class Dates(ndb.model):
    ...
    date = ndb         


        

Answer 1

Use a DateProperty. Then you can use a simple == query:

>>> import datetime
>>> from google.appengine.ext.ndb import *

>>> class D(Model):
...   d = DateProperty()
...

>>> d = D(d=datetime.date.today())

>>> d.put()
Key('D', 9)

>>> d
D(key=Key('D', 9), d=datetime.date(2013, 2, 20))

>>> D.query(D.d == datetime.date.today()).fetch()
[D(key=Key('D', 9), d=datetime.date(2013, 2, 20))]
