[baseten-users] Baseten Examples

[Michael Ruepp]

Hi all,

I am quite new to Baseten/Core Data and Bindings. I went through the  
tutorial provided, the introspection and the stickies as well as the  
manual.

No I try to create a simple solution with two tables (table_a and  
table_b. each with just one column called "name" and relationship in  
table_a is called table_b and vice versa), a one-to many relationship  
(table_a one, table_b many) and four buttons (table_a.add.  
table_a.remove and table_b.add table_b.remove):

Data Model is ok, baseten import ok

1. I want to populate two nstableviews. I can create objects in  
table_a, and when I create objects in table_b, these will be in  
relation to the selected object in table_a. So when I select object in  
table_a, I want table_b to show all related objects to object in  
table_a.

I am really stuck, messed around with bindings, tried to populate the  
contentarray of table_b by binding it to the table_a with selection  
and baseten name of the relationship, no success.
Is such a solution possible entirely in interface builder with bindings?

How can I tell the add button of table_b to use the relationship to  
the selected object in table_a and to check first if an object is  
selected?

Can someone lead me on the right track?


2. How can I achive the same setting, but show the data in a  
NSOutlineView or NSBrowser? Do I have to connect to a  
NSTreeController? And how can I do that?

3. I would be very thankful if someone could write the baseten  
tutorial maybe with two tables and a one to many relationship or at  
least with one table entirely in code. There exists so few examples  
for coding, I´d appreciate it very much because the learning curve  
would be much faster when seeing the code and at least more complex  
examples.

Thanks for your kind support,

Mike
