Right, well I understand that. In fact that is how I would do it
traditionally in a J2EE environment but my understanding is that some of
this should be done auto-magically with the Tapestry/Hibernate combination.
So for example, let's say we have a game application where a User can start
a game and invite players. We have the User entity:
@Entity
public class User {
public String firstName;
public String lastName;
@Validate("required")
public String userID;
@Id
@Validate("required,email")
public String email;
@Validate("required")
public String password;
@NonVisual
public boolean validated;
}
And making the pages/user/CreateUser.java and .tml is pretty trivial:
public class CreateUser
{
@Property
private User user;
}
//************************
<html t:type="layout" title="Create New User"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd";>
<t:beaneditform object="user"/>
</html>
But what about the game class? The entity is easy:
@Entity
public class Game {
@Id
@Validate("required")
public String gameID;
@MayToOne
public User gameOwner;
public String gameType;
public Game() {}
}
But the fact that this entity refers to a gameOwner changes things. I am
using the ManyToOne since a user can start multiple games, I think /maybe/ I
should use @NonVisual since the person creating the game doesn't specify the
gameOwner but I'm not sure.
Now what does the pages/game/CreateGame.java class look like? And the tml?
this is where I am getting lost. I need to supply the User information of
the current user as the GameOwner and I would traditionally do this with an
embedded hidden tag in a JSP:
<input type="hidden" name="userID" value="<%=
user.getUserID() %>" />
But what is the best way to do it with Tapestry/Hibernate?
