Updating the Content Store

[Skidoo]

Hi - I'm trying to update a content object in the Ning content store, but for some reason it's not working.

Here's the code I'm trying to use to update the content object ...

function write_data ($user, $quiz_name, $correct_answers, $incorrect_answers, $answer_list) {        $contentQuery = XN_Query::create('Content');
        $contentQuery->filter('type','eic','My Quiz');

        $contentQuery->filter('owner');

        $contentQuery->filter('my->uid','=',$user);

        $results = $contentQuery->execute();



        foreach($results as $resultsdata) {

        }



        $contentObject = XN_Content::load($resultsdata->id);



        $contentObject->my->correct += $correct_answers;

        $contentObject->my->incorrect += $incorrect_answers;



        if ($quiz_name == "test_quiz") {

                $contentObject->my->test_quiz = 'true';

                $contentObject->my->test_quiz_answers = $answer_list;

        }



        if ($quiz_name == "test_quiz2") {

                $contentObject->my->test_quiz2 = 'true';

                $contentObject->my->test_quiz2_answers = $answer_list;

        }



        $contentObject->save();

}

When I run the code above, I get the following error message ...

Fatal error:  Uncaught exception 'XN_Exception' with message 'Failed to save content:XN_Content:

Anyone have any ideas as to why I'm getting this error message. Thanks in advance for the help.

Hi Skidoo,

For the my->correct attribute the content store is expecting a string, but you're giving it a numeric value; it may be expecting a string because in previous saves of this type (incidentally it's a good idea to avoid creating types with spaces in the name) you saved a string value there, or you didn't specify a type, so it defaulted to string. You should be able to update the value for that attribute (and my->incorrect) to be strings prior to saving. Also, if you've retrieved a content item via a query, you don't need to load it a second time before performing any updates on it.

Thanks,
Phil

Hi Phil,

I have this problem right now, but your explanation doesn't make much sense to me... We just did a 3.1.5 merge. The BlogPost W_Model has an attribute $lastViewedOn which is an XN_Attribute::DATE type. When I create new blog post, it won't save (see log excerpt below). So this is the first time the content is being created and saved with a date type, not a string, so why is it failing? Thanks!

Hi Ted,

It's likely that a content object was created at some point that didn't specify that that attribute type should be a date, so it defaulted to a string and created the current problem.

You should be able to fix it like this:

$shape = XN_Shape::load('BlogPost');
if ($shape) {

    $shape->setAttribute('my.lastViewedOn', 'date');

    $shape->save();

}

Thanks,
Phil
