Question

I am using Play framework with Ebean. I have two models, below are the code:

public class User extends Model {
    @Id 
    public Long id;

    public String name;
   /* rest of attributes */

    public static Finder<Long,User> find = new Finder<Long,User>(
          Long.class, User.class
    );
}

public class Admin extends Model {
    @Id 
    public Long id;

    @OneToOne
    public User user;
    /* rest of attributes */

    public static Finder<Long,Admin> find = new Finder<Long,Admin>(
        Long.class, Admin.class
    );
}

When I do Logger.info(admin.user.name) in Java, I can see the name of the admin. But when I pass the Java object to Scala using view render, if I do @admin.user.id, I can still get the id, but if I do @admin.user.name, I get nothing (with no error). I’m just wonder how can I access the name attribute from a joined table?

Problem solved.
Before when I do the fetching, I did

Admin.find.where()
    .ilike("user.name", "%" + filter + "%")        
    .orderBy("user."+sortBy + " " + order)
    .findPagingList(pageSize)
    .getPage(page);  

After changing to

Admin.find.fetch("user", new FetchConfig().query())
    .where()
    .ilike("user.name", "%" + filter + "%")        
    .orderBy("user."+sortBy + " " + order)
    .findPagingList(pageSize)
    .getPage(page);  

It successfully displayed instance variables on Scala.
