I looked at the "zentasks" sample code to learn some basic user login and security stuff. The Appication controller has an authenticate method , and during that method the User.authenticate method is called. Here are a couple code snippets from those links:
public static Result authenticate() {
Form<Login> loginForm = form(Login.class).bindFromRequest();
if(loginForm.hasErrors()) {
return badRequest(login.render(loginForm));
} else {
session("email", loginForm.get().email);
return redirect(
routes.Projects.index()
);
}
}
...
public static class Login {
public String email;
public String password;
public String validate() {
if(User.authenticate(email, password) == null) {
return "Invalid user or password";
}
return null;
}
}
As you can see, if it authenticates (ie, finds a User object), the authenticate
method adds "email" to the session. I'd like to add the full user object instead, but in the controller action, where I have the session, I don't have the User
object. I don't want to requery the database, I'd like to use the same User
object that was just found in Login.validate
. What's a good way to do that?
Is there a reason you can't simply add a field to your login class?
public static class Login {
public String email;
public String password;
public User user;
public String validate() {
user = User.authenticate(email, password);
if(user == null) {
return "Invalid user or password";
}
return null;
}
}
Not that this will necessarily help you, looking at the API it seems you can't add an object to the session, only Strings.
