Did you try dataSource.setAuxiliaryQualifier(aQualifier);
I had been reading up about that on the weekend. Don't know about most
people, but I find I need to read the documentation a couple of times,
do heaps of experiments to get something going, then read the doc's a
few more times to cement the ideas.
My current stage is replacing the standard call for storedValueForKey()
with a specific objectsWithFetchSpecification() using the desired
target entity, and qualifiers for the related record I am calling from,
along with my filter qualifier. Seems to work, and only requests the
objects I want (rather than getting all first and then filtering). I
also have put in a conditional that the NSArray I am fetching into is
null so I don't repeatedly do the fetch.
My only concerns are that I may be missing out on some WO magic, such
as the fetched array being refreshed (seems ok in testing though) and
that the EOEditingContext recognises the relationship between the
source and destination objects.
Now that part is working, I will give the dataSource stuff a go. Will
probably take me a week to digest everything, but I would be pleased if
the suggested technique works as desired.
Thanks for the help and advice by everyone on this.
Ray.
