Mark - I understand where you are coming from, and did try your suggestion. But I still am NOT getting a user EO instance (I get null per the debugger).

Actually I checked the WO docs and both valueForKeyPath AND valueForKey are valid methods of the Session class. Problem is what is the correct syntax. The docs say object.valueForKey(string), and your suggestion provided the object part (ie session()) (I also tried your input + valueForKeyPath but Eclipse complained about 'no such key = session')

So I still am at a loss on how to retrieve a user EO from the session. :-(

But thanks for your help/input!

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! ;-)


Regards,
Mark
