Chris, thank you!
the database itself is designed as a relational database would be,
it's quite large actually, I just posted here two tables to illustrate
the problem.
The software I am building is a personal one, to help me track my
budget.
the goal is to import my transactions at the end of every month, and
compare
it to the budget, and the software will point out the out of budget
spending habits so I can either budget them in,
or correct them.
I know other software out there do that, but it's a learning
project ... to learn cocoa :)
and I want to make it really simple, import, compare, report. that's
all.
>>Instead of different types of transactions, transactions always
have debits and credits.
humm, not in the bank statement, they also have CHECK. and I want to
track that too.
I retrieve/create/insert (not quite sure yet :)) an object from the
context, and set the values like this.
NSManagedObject *transaction = [NSEntityDescription
insertNewObjectForEntityForName:@"Transactions"
inManagedObjectContext:[self
managedObjectContext]];
This is inserting a new instance of that entity in the managed
object context.
That's how he manual says to insert records, kind of works well, if
you do not have relationships.
it crashes on me as soon as i have a relationship on the table i want
to insert to.
The Transaction(tr) Object Used in the code above is defined like
this:
@interface OFXTransaction : NSObject {
Why do you even have this class? It looks like its whole purpose is
to replicate what you already have defined in your Transaction
entity. You can just use an NSManagedObject subclass to represent
one directly.
This class is the class used to import the data from my OFX file, My
OFX importer has a class for every section of the OFX specification.
Yes, you will need to insert or fetch an instance of your
TransactionType entity. You'll just take that and set it as the
value of your Transaction instance's transactionType relationship.
Cool, that's simple.
Hope this helps!
It does thanks Chris.
