Hi,
I'm not sure my subject is understandable, anyway.
Assuming I have an object "x", I'm manipulating it in an editing
context. At a certain point I need to get the original object (the
one from the database) but without changing anything to the one in
my editing context.
How could I do that?
I need the object in its globality, so if I can get the object
directly and not a dictionary of its values it's better:)
You can answer "bla bla project wonder":) but please point me to
the correct method as I didn't find it for now;)
What, exactly, is it that you need? You can't have two different
versions of the same EO in the same EOF stack. Avoiding that is one
of the central objectives of EOF. Do you need it as an object or
just as a dictionary of values. If you need it as an EO, you can't
have it. If you need just a dictionary of values, then which
dictionary? The values the last time that EOF fetched it from the
database (or successfully saved it to the database):
NSDictionary valuesAsLastFetchedFromTheDatabase = eo.editingContext
().committedSnapshotForObject(eo);
If you need a dictionary of the current values in the database, use
EOUtilities.qualifierForEnterpriseObject and a fetch spec set for raw
rows.
