使用getAttributes方法时出错:“在非对象上调用成员函数getAttributes()”。
现在,在我的控制器中:
$notifications = Notifications::return_new()->getAttributes();
var_dump($notifications);
在模型中
public static function return_new(){
return Notifications::find()->where(['is_seen' => 0])->all();
}
现在,Yii文档说getAttribute()接受一个数组作为参数,所以我试过
$notifications = Notifications::return_new()->getAttributes('text');
但它仍然存在同样的错误。有帮助吗?
以下是模型
<?php
namespace frontend\models;
use Yii;
*/
class Notifications extends \yii\db\ActiveRecord
{
public static function tableName()
{
return 'notifications';
}
public function rules()
{
return [
[['created_on', 'user_id', 'text'], 'required'],
[['user_id'], 'integer'],
[['created_on'], 'safe'],
[['text'], 'string', 'max' => 255]
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'created_on' => 'Created On',
'user_id' => 'User ID',
'text' => 'Text',
];
}
public static function count_new()
{
$new = Notifications::find()->where(['is_seen' => 0])->all();
return count($new);
}
public static function return_new(){
return Notifications::find()->where(['is_seen' => 0])->all();
}
public function return_all(){
return Notifications::find()->all();
}
public static function checkst(){
return Notifications::find()->where(['id' => 3])->one();
}
public function return_by_date () {
// write something here.
}
}
答案 0 :(得分:1)
如果您使用libvlc_media_stats_t stats;
if (libvlc_media_get_stats(vlcmedia, &stats))
{
long p=libvlc_media_player_get_time(vlcmediaplayer);
if (p)
bitrate=stats.i_read_bytes/p;
}
,您将获得一组模型,然后您应该参考
all()
否则你可以
Notifications::return_new()[0]->getAttributes();
在这种情况下你可以使用
public static function return_new(){
return Notifications::find()->where(['is_seen' => 0])->one();
}
