macOS managedObjectModel relationship question(core data)

[dj.mooky]

So... I am using bindings, that I learned from reading/watching tutorials for an older version of IB. I know I am the one screwing up on this one I just do not know where, or what to do.


I've got two entities basically
Player and Hand

There's a too many to too many relationship going on here, with appropriate restrictions

I have two tables set up, one with names of all Players, and the other is currently just a list of every number associated with a hand

How is it I make my (hand)second table ONLY show data associated via relationship to a player?

EG: I click on me(dj.mooky) I am not interested in viewing a Hand that does is not associated to the selected Player.

I've got it all set up in bindings like I said

This will be just tremendously helpful once I get the real statistical engine of my app going where I'll suddenly have 5-6 entities instead of just the two during the alpha proof of concept phase.

Current setup is table 1 is bound to Player showing value userName

I know table 2 is setup wrong, but it is bound to Hand showing value handNumber

Thanks in advance

Bind it to Player.selection.hands.handNumber. And by "it", I'm pretty sure (but not 100% sure) that I mean the NSTableColumn, not the table itself.

Thanks for the answer, unfortunately your insight has only illuminated my even further screw up in writing the classes associated with my entities

This is good though... learning to spot my mistakes, and finding out what they are is an amazing thing

When I attempt doing it as you suggested, it gives me a KVC error

I'm currently doing a search to figure out exactly what my error is, I've seen it online, I just did not know how vital it was at the time. I'll post a link in here when I find it incase anyone else ever has this problem.

So, I think I have found my problem... I don't have time to test it out, however I did not take the time to define the properties in my .h file..
