Hi there! I'm new to python and app engine, I need some help with this:
*class* Profile (db.Model):
name = db.StringProperty()
backup_date = db.DateProperty()
*class* BoxInfo (db.Model):
source = db.TextProperty()
index = db.IntegerProperty()
profile= db.ReferenceProperty(Profile, collection_name='boxes')
*How can I do this?*
query = model.BoxInfo.all().filter("profile.backup_date =", None)
*I have also tried this way, with no sucess:*
query = db.GqlQuery("select * from BoxInfo where profile in (select * form
Profile where backup_date = :1)", None)
Which gives me:
BadQueryError: Parse Error: Parameter list requires literal or reference
parameter at symbol select
Thanks
