Question

I really hope someone can help on this because I’m learning cocoa and have hit a road block.

I am trying to model a simple poker tournament. For now, my entities are simply a Tournament (with a number) and a Player (with a Name). A Tournament has an array of Players.

I can bind two independent table views to display the tournaments and the players just fine. But I want the players table view to just show the players that belong to the selected tournament from the first table view.

Each has it’s own array controller. I have tried a variety of different bindings for the second (players) table but to no avail. Has anyone accomplished this? If so maybe you could spell it out for me, as I there are few examples online.

• Update
  I can now ALMOST get where I need to, mostly through rial and error and hours of googling. I have bound the player AC’s content to the tournament AC, with controller key ‘selected objects’ and Model Key Path ‘players’, which is the name of the array in my Tournament entity.

I have the bound the column in the players table view to this second Player AC, controller key arranged objects. But what to put in the Model Key Path? I know it is working because if I stick @count in there I get the correct number of players for the selected tournament. But ‘name’ and ‘player.name’ are no good. Is there any kind of ‘item.name’ or ‘players.item.name’ I can try?

Sooo close, thanks for the help so far:

I think this tutorial will help you. They also create a master/detail view.

In short: Bind the contentArray of your player’s array controller to the tournament’s array controller, set ControllerKey to selection and the remaining properties accordingly to your model.
