Here is an example from my own code.
I have an object:
from google.appengine.ext import db
from Owner import Owner
class ImageFile(db.Model):
owner = db.ReferenceProperty(Owner)
caption = db.StringProperty()
description = db.TextProperty()
image = db.BlobProperty()
date = db.DateTimeProperty(auto_now_add=True)
public = db.BooleanProperty()
I have an update method within another class that has this import
from json import JsonReader
The image data gets updated via this post method on the class:
def post(self):
reader = JsonReader()
currentUser = getCurrentUserOwner()
tempImage = reader.read(self.request.body)
if not currentUser is None:
requestedImage = db.get(tempImage['key'])
if requestedImage.owner.key() == currentUser.key():
requestedImage.caption = tempImage['caption']
requestedImage.description = tempImage['description']
requestedImage.public = tempImage['public']
requestedImage.put()
This is from an intro talk I gave on App Engine. If anyone wants the full

next to do after dumps()...
