For my Play! Application I have a User.class

```
@Entity
public class User extends Model {

@Id
public String email;
public String name;
public String password;

public User(String email, String name, String password) {
  this.email = email;
  this.name = name;
  this.password = password;
}

...
}

```

Everytime I ask on /user/{id}.json for a user object, I want to prevent that the password string is sent. How to do that? Is that the normal use case or is there another way to deal with it?
