Weird behavior with relations and AR

I’m experiencing a weird error during the rendering of a page which loads a Portlet.

"Trying to get property of non-object…"

The odd thing is, when I changed the relation name from ‘venueCity’ to anything else (e.g. ‘venuecity’, ‘loc’, ‘location’) I stopped getting the error… until after a certain amount of time, it breaks again.

It seems to be isolated to a certain type of object that I deal with… but it’s strange that, simply changing the name would cause it to work/break.


public function relations()


	return array(

		'venue' => array(self::BELONGS_TO, 'Venues', 'venue_id'),

		'venueCity' => array(self::BELONGS_TO, 'Venues', 'venue_id',

			'select'=>'city, geo_state_abbr'





protected function renderContent()


	if(isset($this->parent)) {

		$parent = $this->parent;

	} else {

		$parent = $this->getController()->loadParentModel();


	if(!empty($parent->city)) {

		$location = $parent->city . ', ' . $parent->geo_state_abbr;

	} else {

		$children = $parent->children;

		$venue = $children[0]->venueCity;

		$location = $venue->city . ', ' . $venue->geo_state_abbr; // ERROR HAPPENS HERE







I’m using Yii 1.1.7


what database engine are you using?

if it is sqlite, i think you should override

the primaryKey() method in your model. :)
