ndb query error with datetime field - Google App Engine

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

I expanded @Guido van Rossum code snippet to include <> and timedelta for calculations, mostly for my own satisfaction

import datetime
from datetime import timedelta

from google.appengine.ext.ndb import *

class D(Model):
  d = DateProperty()

now = datetime.date.today()
date1 =  now-timedelta(+500)
date2 =  now-timedelta(+5)

d1 = D(d=now)
d2 = D(d=date1)
d3 = D(d=date2)

d1.put()
d2.put()
d3.put()

date2 =  now-timedelta(+50)

result1 = D.query(D.d == now).fetch(4)
result2 = D.query(D.d > date2).fetch(2)
result3 = D.query(D.d < date2).fetch(2)

result4 = D.query(D.d >= date2, D.d <= now).fetch(2)

print result1
print "+++++++"
print result2
print "+++++++"
print result3
print "+++++++"
print result4
