Hi,
My application has a model that just contains two db.ReferenceProperty
fields pointing to the same model type. I want to be able to test the
existence of an entry in the data store for a given pair. In my app I
couldn't get it working so I tried this in the local development
console:
class A(db.Model):
name = db.StringProperty()
class B(db.Model):
alpha = db.ReferenceProperty(A, collection_name='alpha')
beta = db.ReferenceProperty(A, collection_name='beta')
a1 = A(name='one')
a1.put()
a2 = A(name='two')
a2.put()
b = B(alpha=a1, beta=a2)
b.put()
q = B.all().filter('alpha=', a1).filter('beta=', a2)
print q.count()
It prints out "0" instead of the "1" I'd expect. Any ideas why?
Ian
