Thanks Chuck,
I have updated the code using your suggestion as a starting base. I
have separated all the steps of the fetch specification as I was
learning what each thing meant. The code above is returning
ApplicationUsers and I am pretty sure I need to replace that with
"Meeting". I think this makes the prefetching unnecessary.
public NSArray meetingRepetition()
{
ApplicationUser applicationUser = (ApplicationUser)
valueForKeyPath("session.user");
EOEditingContext ec = applicationUser.editingContext();
return EOUtilities.objectsWithQualifierFormat(ec,
"Meeting",
"user = %@",
new NSArray
(applicationUser));
}
'scuse the formatting. :-)
Got lost in the forest on the first answer. I answered "How do I set
the qualifier for the user that is logged in?" rather than the
question you were really wanting an answer to.
Is perhaps what you are after? This assumes that Meeting has a user
() relationship to ApplicationUser.
Chuck
Here is the changed code:
public NSArray meetingRepetition()
{
EOQualifier myQualifier;
NSArray mySortOrderings;
ApplicationUser applicationUser = (ApplicationUser)
valueForKeyPath("session.user");
EOEditingContext ec = applicationUser.editingContext();
EOFetchSpecification fetchSpec = new EOFetchSpecification();
fetchSpec.setEntityName("Meeting");
myQualifier = EOUtilities.qualifierForEnterpriseObject(ec,
applicationUser);
fetchSpec.setQualifier(myQualifier);
mySortOrderings = NSArray.EmptyArray;
fetchSpec.setSortOrderings(mySortOrderings);
fetchSpec.setRefreshesRefetchedObjects(true);
// fetchSpec.setPrefetchingRelationshipKeyPaths(new NSArray
("meetings"));
Session sess = (Session)session();
EOEditingContext myEC = sess.defaultEditingContext();
meetingRepetition =
myEC.objectsWithFetchSpecification(fetchSpec);
return meetingRepetition;
}
This gives an application error (see below) on the many to many
relationship. How do I set the qualifier for the user that is
logged in?
