[google-appengine] Re: Path from Key
Hey Colin, I've been using this: def key_to_path(model): key = model.key() output = [] while key: name = key.name() if name is None: output.append(key.id()) else: output.append(name) output.append(key.kind()) key = key.parent() output.reverse() return output 2009/5/26 Nick Johnson (Google) : > > Hi Colin, > > You're correct - there's currently no built-in method to do this, and > recursively (or iteratively, with a stack) calling key.parent() is > your best option. > > -Nick Johnson > > On Mon, May 25, 2009 at 3:17 AM, hawkett wrote: >> >> Hi, >> >> There is a method Key.from_path() - which lets you supply the path >> to construct the key.

Hi Colin, You're correct - there's currently no built-in method to do this, and recursively (or iteratively, with a stack) calling key.parent() is your best option. -Nick Johnson On Mon, May 25, 2009 at 3:17 AM, hawkett wrote: > > Hi, > > There is a method Key.from_path() - which lets you supply the path > to construct the key.

Hi , I'm trying to deploy an application through eclipse. I have used my gmail id only . It gives me the following error. java.io.IOException: Error posting to URL: http://appengine.google.com/api/appversion/create?app_id=roshni-basu&version=1&; 400 Bad Request Invalid runtime or the current user is not authorized to use it. I did not get any mail saying i have been registered also. How do I solve this issue??
