user = db.GqlQuery("SELECT * FROM Users WHERE account = :1", account).get() # Notice we add the call to get() here user.url = referrer user.put()

Something you are saying isnt correct, because subscripting on the GqlQuery instance isn't even supported. You call get(), but don't actually keep the returned entity, which is what you should change the properties on and call the put() method of.

Hello there, I've problem with datastore on google AppEngine, .put() function seems to not update the entity previously edited:

I wish to perform a method to insert a new object in datastore and edit it if it already exist.

I've this Class:

class Users(db.Model): account = db.StringProperty(required=True) url = db.StringProperty(required=True)

and this code somewhere in the main: suppose: account="something" and referer="http://somewhere", they are two strings

user=db.GqlQuery("SELECT * FROM Users WHERE account = :1", account) if (user.get()): user[0].url=referer user[0].put() else: p1=Users(account=account, url=referer) p1.put()

All works OK except: re-sending to datastore with: user[0].put() I've also tried: db.put(user) but same results!

Datastore keep the old value!

Hope that someone could help me,

regards,

Alessandro.
