How to decode a Google App Engine entity Key path str in Python?

Question

In Google App Engine, an entity has a Key. A key can be made from a path, in which case str(key) is an opaque hex string. Example:

from google.appengine.ex         


        

Answer 1

Once you have the Key object (which can be created by passing that opaque identifier to the constructor), use Key.to_path() to get the path of a Key as a list. For example:

from google.appengine.ext import db
opaque_id = 'agNiYXpyDAsSA2ZvbyIDYmFyDA'
path = db.Key(opaque_id).to_path()
