yii "Trying to get property of non-object" at view.php - php

Question

I have a strange problem with my yii application. I have two tables in my database Players - id, name, team_id and Teams - id, name. I can create new players but when I want to see player's profile there is an error -"Trying to get property of non-object" at this line:
'value'=>$model->team->NAME,
The most strange problem is that when I test url for players with Ids 1 and 2 everything is okay and I see the correct information, but for other ids I have this problem. Here is part of my code:
view.php
<?php $this->widget('zii.widgets.CDetailView', array(
'data'=>$model,
'attributes'=>array(
'ID',
'NAME',
'TEAM_ID',
array(
'label'=>'Отбор',
'type'=>'text',
'value'=>$model->team->NAME,
),
),
)); ?>
Players.php
public function relations()
return array(
'team' => array(self::BELONGS_TO, 'TEAMS', 'ID'),
);
}
Teams.php
public function relations()
{
// NOTE: you may need to adjust the relation name and the related
// class name for the relations automatically generated below.
return array(
'player' => array(self::HAS_MANY, 'PLAYERS', 'ID'),
);
}
PlayersController.php
public function actionView($id)
{
$teams = new CActiveDataProvider('Teams');
$players = new CActiveDataProvider('Players');
$this->render('view', array(
'model'=>$this->loadModel($id),
));
}

Answer 1

Seems like you need to fix bug with relations in Players model:
public function relations()
return array(
'team' => array(self::BELONGS_TO, 'TEAMS', 'TEAM_ID'), // TEAM_ID instead of ID
);
}
