Hello,
I have a basic question on how to access the logged in user for
later use in updates. After authenticating a user I enter him into
the session, but when I later try to retrieve this user in another
page, it fails(returns null).
So in my main page I record the user as follows:
if (_password.equals(password)) { EOEnterpriseObject
user = EOUtilities.objectMatchingKeyAndValue(session
().defaultEditingContext(), "User", "name", username);
// set the
session.user session
().takeValueForKey(user, "user");
And on another page to add a new transaction which needs the user
relation attribute(as a foreign key):
EOEnterpriseObject user = (EOEnterpriseObject) valueForKeyPath
("session.user"); // user evals to null???
Try changing this to:
EOEnterpriseObject user = (EOEnterpriseObject)session().valueForKey
("user");
valueForKeyPath is useful, but I don't think it can do what you're
asking of it here.
purchase.addObjectToBothSidesOfRelationshipWithKey(user, "user");
The save fails because user is a required attribute. And I'm not
sure if I am not properly storing the user in the session, or not
properly retrieving the user from the session.
Can anyone see what I am doing wrong or suggest another approach?
TIA
Personally, I usually make currentUser an actual variable in Session.
(Private, with public accessor methods, of course! ;-)

Mark
