Hello all once again.
I have been searching but I hadn't found something useful, so please before if
you know a place I can look at let me know.
I have these 3 Entities
ExpenditureGroup:
name
icon.
-----------------------
toExpenditures. ->>
Expenditure
creationDate
location
total
--------------------
toExpenditureGroup ->
toExpenditureDetails ->>
ExpenditureDetail
detailDescrb
subTotal
----------------------
toExpenditure ->
also I have an arrayController that fetches all the ExpenditureGroup Entities
called _expenditureGorupArrayController.
in my predicate editor I added the NSPredicateEditorRowTemplates with key paths
for toExpenditures.location, toExpenditures.creationDate,
toExpenditures.total, toExpenditures.toExpenditrueDetails.detailDescrb and
finally toExpenditures.toExpenditureDetails.subTotal.
I dunno if those last 2 are ok.. my guess NO.
anyway, when I set the predicate, Im setting into the
_expenditureGroupArrayController setFilterPredicate, and pass the predicate I
just created, but nothing seems to work.
I was reading apple docs, and I see here I need to do some join, but there it
says its not possible, that I have to fetch first something and then using
operators get the other required objects.
I really dunno even if the key paths I set for the templates are ok or no,
because I thought that If im gonna apply the predicate to the arraycontroller
with entity is ExpenditureGroup, then I can simple use the relationships.
Any suggestion?
Thx
Gustavo
