    <p>Ok, I thought I had this but I am not getting the results that I am expecting. Hopefully someone can help.</p> <p>I have two entities Person and Timesheet with one attribute to-many relationship: Person.timesheet&lt;--->>Timesheet.user. The code below works but when I try to add a second timesheet entry it seems to override the first?</p> <p>I have looked at the Apple Docs and they are a little vague on this subject.</p> <pre><code>//Add NSManagedObjectContext *context = self.managedObjectContext; Person *personAdded = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:context]; Timesheet *timesheet = [NSEntityDescription insertNewObjectForEntityForName:@"Timesheet" inManagedObjectContext:context];; timesheet.time = @"10:00 Friday"; timesheet.timestamp = [NSDate date]; NSSet *timesheetSet = [NSSet setWithObject:timesheet]; personAdded.name = @"Darren"; personAdded.job = @"Job to be Done"; personAdded.timesheet = timesheetSet; NSError *error = nil; [context save:&amp;error]; if (error) { NSLog(@"[ERROR] COREDATA: Save raised an error - '%@'", [error description]); } NSLog(@"[SUCCESS] COREDATA: Inserted new User to database!"); // Load NSEntityDescription *personEntity = [NSEntityDescription entityForName:@"Person" inManagedObjectContext:context]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; [request setEntity: personEntity]; error = nil; NSArray *results = [context executeFetchRequest:request error:&amp;error]; if (!results || error) { NSLog(@"[ERROR] COREDATA: Fetch request raised an error - '%@'", [error description]); [request release]; } NSLog(@"Results: %@",results); Person *firstUser = [results objectAtIndex:0]; NSLog(@"First User's name: %@",firstUser.name); NSLog(@"First User's time %@",[[firstUser.timesheet anyObject] valueForKeyPath:@"timestamp"]); </code></pre> <p>I am wondering if it could be because I am actually setting the Person.timesheet key with the NSSet and not the actual Table? OR could it be that I am not calling the results correctly?</p> <p>Thanks, Darren</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
