yii”;尝试获取非对象“”的属性;请访问view.php


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

我的yii应用程序出现了一个奇怪的问题。我的数据库Players-id,name,team_id和Teams-id,name中有两个表。我可以创建新的玩家,但当我想查看玩家的个人资料时,出现了一个错误——"试图获取非对象的属性":

'value'=>$model->team->NAME,

最奇怪的问题是,当我为ID为1和2的玩家测试url时,一切都很好,我看到了正确的信息,但对于其他ID,我有这个问题。这是我的部分代码:

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,
    ),
),
)); ?>

播放器.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),
    ));
}

似乎需要修复Players模型中relations的错误:

public function relations()
    return array(
      'team' => array(self::BELONGS_TO, 'TEAMS', 'TEAM_ID'), // TEAM_ID instead of ID
    );
}
