All right, I found my mistake.
I was not creating the entity description used by the fetch request
properly :
entity = [NSEntityDescription entityForName:@"Brand"
inManagedObjectContext:managedObjectContext];

Hi guys,
Is it normal that newly inserted objects do not appear in the
results returned by exceuteFetchRequest ?
Here is the code I'm using :
- (void)insertNewBrandWithName:(NSString *) newBrandName
{
Brand * selectedBrand = nil;
selectedBrand = [[[Brand alloc] initWithEntity:
[NSEntityDescription entityForName:@"Brand"
inManagedObjectContext:managedObjectContext]
insertIntoManagedObjectContext:managedObjectContext] autorelease];
NSLog (@" insertedObjects = %@", [managedObjectContext
insertedObjects]);
// TEST
NSFetchRequest * fetchRequest = [[[NSFetchRequest alloc] init]
autorelease];
NSEntityDescription * entity = [[[NSEntityDescription alloc] init]
autorelease];
NSArray * results = nil;
[entity setName:@"Brand"];
[fetchRequest setEntity:entity];
results = [managedObjectContext executeFetchRequest:fetchRequest
error:nil];
NSLog (@" results = %@", results);
}
The first NSLog call confirms that me newly created Brand has
correctly been inserted in the MOC. But the second NSLog call
confirms that it is not present in the context : the array returned
by executeFetchRequest contains all the Brands but the one newly
inserted.
Is there something I am doing wrong here or is there a logic that I
did not understood about MOC ?
Thanks,
Eric.
