I figure I need to build an NSArray and populate it with the values
from the Course_description table and then use that to populate the
course_descriptionID in the Course table, but exactly how to do that
is just out of my reach.
First thing, your naming convention looks a little wonky. Java
usually uses CamelCase for class and method names.
So:
Your Java would look something like this:
public Course course; //assume exists
public CourseDescription courseDescriptionItem;
//
//
public NSArray allCourseDescription s() {
EOEditingContext ec = ((Session)session()).defaultEditingContext();
return EOUtilities.objectsForEntityNamed(ec, "CourseDescription");
}
// the magic of getting a wopopup to work lie in these two methods
public CourseDescription selectedCourseDescription() {
return course.courseDescription();
}
public void setSelectedCourseDescription(CourseDescription
aDescription) {
course.addObjectToBothSidesOfRelationshipWithKey(aDescription
"courseDescription");
}
Your .wod would look something like this:
CourseDescPopup: WOPopupButton {
list = allCourseDescription;
item = courseDescriptionItem;
displayString = courseDescription Item.name;
selection = selectedCourseDescription;
}
