Я часами пытался получить отношения многих ко многим, чтобы сохранить с помощью Castle ActiveRecord. Что я делаю неправильно? Я не могу найти ничего в документации или в Google. В базе данных есть данные.
Курсы имеют много-много отношений с Книгами.
Тестовый код.
Database.Course c = new Database.Course();
c.Number = "CS 433";
c.Name = "Databases";
c.Size = 34;
c.Books = Database.Book.FindAll();
c.Save();
Также не работает
foreach(Database.Book b in Database.Book.FindAll()){
c.Books.Add(b);
}
