I have two entities:
public class People {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private List<Key> contactmethods;
}
public class ContactMethod {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String contactmethodaddress;
}
Every time I add a new contact method, i.e. phone number, email, etc I
add an entry into the person's list so we know all of the ways we can
contact them. Now, I want to find out who a person is based on one of
those entries.
So if I have the key for a specific contactmethod, how do I select the
Person(s) to which it belongs? I have tried:
javax.jdo.Query q = pm.newQuery(People.class);
q.setFilter("this.contactmethods.contains(pContactMethod)"); and
q.setFilter("contactmethods == pContactMethod");
q.declareImports("import com.google.appengine.api.datastore.Key");
q.declareParameters("Key pContactMethod");
List<People> allPeople = (List<People>)
pm.newQuery(q).execute(lContactMethodKey);
Where lContactMethodKey is the Key of the contact method being
searched for.
either way I get:
javax.jdo.JDOFatalUserException: Exception converting
com.appointment.datastoreobjects.peo...@2c453c47 to an internal key.
Received a request to find an object of type
com.appointment.datastoreobjects.People identified by
com.appointment.datastoreobjects.peo...@2c453c47. This is not a valid
representation of a primary key for an instance of
com.appointment.datastoreobjects.People.
Thanks for any insight you can give!
