GAE+Objectify - Parameterized type com.googlecode.objectify.Ref not supported

Question

I am using Google App engine1.9.3, Eclipse, Objectify5.03. My Class is as follows:

import com.googlecode.objectify.Ref;
import com.googlecode.objectify.annot         


        

Answer 1

ApiResourceProperty annotation does not work for Google Emdpoints+Objectify combinations as Ref or Key is Objectify specific class and Google Endpoints does not recognize them and will give a error when you try to generate the Client Libraries. I changed the User class as below.

 @Id private Long userId;
 @Index private String userName;
 @Load private UserDetails userDetails;
 @Load private UserPassword userPassword;
 @Load private ArrayList userAccounts;

 //getters and setters

When I retrieve the user by user name as below, I get the User, UserDetails, UserPassword and also the list of User accounts thru the getters (in one shot)

@ApiMethod(name = "getUserByName", path = "get_user_by_name")
public User getUserByName(@Named("userName") String userName) {

    User user = null;
    try {
         user = ofy().load().type(User.class).filter("userName", userName).first().now();
         if(user != null)
             log.info("UserEndpoint.getUserByName...user retrieved="+user.getUserId());
         else
             log.info("UserEndpoint.getUserByName...user is null");
    } catch(Exception e) {
        log.info("UserEndpoint.getUserByName...exception="+e.getMessage());
    }
    return user;
}

When I use the Datastore Viewer on Google Console to view the data, I see some entries in the userDetails, userPassword and Accounts columns in the User table. I assume that these are references to the actual data in their respective tables and not a copy of the data itself. Hope this helps.
