Strange behavior

[christoph...@gmail.com]

Hi all,

I've got 2 models.

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

public User user;
}

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

public String email;
public String name;
}

On my Ship class, i've got this method :
public static List<Ship> getAlls() {
return Ship.all().fetch();
}

First, I created a Ship like this :

Ship s = new Ship();
s.name = "BB";

User u = User.findById(1L);

s.user = u;
s.save();

When I looked in BD, the raw was correct, user id is ok

When I try to read all ships with this method :
return Model.all(Ship.class).fetch();

ship.user is null

Where's the pb ?

Hi,

Is ship.user completely null or does ship.user.id is not null and the rest of the object is null?

Object is null.

I've also tried the sample, with Dog and person, and got a bad
result : after person.save(), dog wasn't save in BD.

My env is : play 1.2.3, siena module 2.0.6

[Pascal Voitot Dev]

can you try to use insert instead of save please?

[christoph...@gmail.com]

Something is really strange, today, I try again the cat and person
sample, now, it's ok :-(

I also tried my models User and Ship after using new copy of them
UserV2 and ShipV2, now it's ok :
user.ship.get() didn't throw NPE..

No lib update, etc...

So Why ?

[Pascal Voitot Dev]

hmmm weird :)
are you using GAE?

[christoph...@gmail.com]

yep, play 1.2.3, gae 1.6.0, siena 2.0.6

I tried to get siena 2.0.7, now after eclipsify, i've got 2 siena
folders in eclipse :-)

[Pascal Voitot Dev]

You should have only one deps to Siena...
Did you run?
play deps --sync

[christoph...@gmail.com]

yep, now it's ok only one siena folder.

I've got 2 play controllers in same application

One simple :

First is :
UserV2 u = UserV2.findById(1L);
u.ship.get();
good result, ship is loaded

Second with @Secure(admin = true) is :
List<UserV2> users = UserV2.getAlls();
for (UserV2 u : users) {
System.out.println(u.name + ":" + u.ship);
}
I've got : null

really hard

More infos, my user seems to be ok in database (H2):

SELECT * FROM USERV2;
ID EMAIL NAME SHIP
1 t...@gmail.com bid 1

[Pascal Voitot Dev]

Did you try?
       System.out.println(u.name + ":" + u.ship.get());

It's ok for my new model UserV2 and ShipV2, but ko for my old ones

you should clean your GAE DB to be sure you don't have corrupted data in it.
I really don't see what happened :)
