How does one test for the presence or absence of a particular property in an Entity? I looked through the docs: http://code.google.com/appengine/docs/python/datastore/gqlreference.html and only found this statement about it:
"Note: conditions of the form property = NULL (which are equivalent) check to see whether a null value is explicitly stored in the datastore for that property. This is not the same as checking to see if the entity lacks any value for the property! Datastore queries which refer to a property never return entities which don't have some value for that property." However it dosen't say what to actually do to determine this condition. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
