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;)
one of the possible ways of doing that is to make object.snapshot()
before changing it and after some time create new editing context ,
fetch the object into it and then do
objectInTheNewEditingContext.updateFromSnapshot()
changes would be made to the objectInTheNewEditingContext only
