Hi all
I was hoping for some advice, being somewhat new to webobjects.
I have a model that is in the form
Building <--->> Room
^ ^
| |
v v
v v
Person_Building Person_Room
^ ^
^ ^
| |
-- > Person <----
Basically a there are many buildings with many rooms in each. A Person can be
granted access to a Building and a limit number of rooms within the building.
No in displaying this I was using a Repetition to display the Buldings in a
list and setting the masterObject to the Person logged in. The Person object
is kept in the Session object.
The problem is when I use a second repetition to display the Rooms for the
build (well that part is easy) but to limit the list of room to the Person
that is logged in is where I am comming apart.
1. Is there a better way to structure this model ?
2 I have tried adding a custom routine to the Building.java class module. The
problem there if I try and access the session().PersionID() routine it
complains about session being unknown. The routine is as follows...
public class Building extends EOGenericRecord {
...
/** @TypeInfo Room */
public NSArray myRooms() {
NSMutableDictionary d = new NSMutableDictionary();
-> // Session s = (Session) session(); !!! Error !!!
-> d.takeValueForKey(s.PersonID, "personName");
d.takeValueForKey(this.roomName(), "roomName");
EOModelGroup mg = EOModelGroup.defaultGroup();
EOFetchSpecification fs = mg.fetchSpecificationNamed("myrooms","Room");
fs = fs.fetchSpecificationWithQualifierBindings(d);
EOEditingContext ec = this.editingContext();
return (NSArray)ec.objectsWithFetchSpecification(fs);
}
...
I know know that session() can not be used in a EOGenericRecord, so I was
wondering if anyone has any other ideas?
Thanks all
These things are hard to describe in a short message, so if more info is
needed just hammer me with it.
