I'm getting an error when trying to filter on ANCESTOR IS locally in
Eclipse. Anyone know what might be the problem? Does anyone have a
working example? Am I forced to use the Low-Level API?
The code is:
PersistenceManager pm =
PMF.get().getPersistenceManager();
Transaction tx = pm.currentTransaction();
try {
tx.begin();
Query query = pm.newQuery(ChildClass.class,
"WHERE ANCESTOR IS pAnc " +
"parameters
com.google.appengine.api.datastore.Key pAnc");
try {
Key ancesterKey =
ParentClass.generateKey(accountId)
.getKey();
Iterable<ChildClass> queryResults =
(Iterable<ChildClass>) query
.execute(ancesterKey,
startDate, endDate);
...
It errors on the execute() method. I currently have no data stored
yet.
Can Google update the docs with a full example?
Portion of expression could not be parsed: ANCESTOR IS pAnc parameters
com.google.appengine.api.datastore.Key pAnc
My code returns the error as JSON to the browser:
{"errorMessage":"Portion of expression could not be parsed: ANCESTOR
IS pAnc parameters com.google.appengine.api.datastore.Key
pAnc","errorClass":"JDOUserException","hasErrors":true,"stackTrace":"\r
