Вот есть 2 кода blog.php - ни в одном из них нельзя создать новый тэг на странице блога и сохранить. Почему так?
<?php
namespace common\models;
use Yii;
use common\models\Blog;
use yii\db\ActiveRecord;
/**
* This is the model class for table "blog".
*
* @property integer $id
* @property string $title
* @property string $text

* @property integer $status_id
* @property integer $sort
*/
class Blog extends \yii\db\ActiveRecord {
public $tags_array;
/**
* @inheritdoc
*/
public static function tableName()
{
return 'blog';
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[['title', 'url'], 'required'],
[['text'], 'string'],
[['url'], 'unique'],
[['status_id', 'sort'], 'integer'],
[['sort'], 'integer','max'=>99, 'min'=>1],
[['title', 'url'], 'string', 'max' => 150],
[['tags_array'],'safe'],
];
}
/**

public function attributeLabels()
{

'author.username'=>'Имя Автора',
'author.email'=>'Почта Автора',
];
}
public static function getStatusList() {
return ['off','on'];
}
public function getStatusName(){
$list = self::getStatusList();
return $list[$this->status_id];
}
public function getAuthor () {
return $this->hasOne (User::className(),['id'=>'user_id']);
}
public function getBlogTag () {
return $this->hasMany(BlogTag::className(),['blog_id'=>'id']);
}
public function getTags()
{
return $this->hasMany(Tag::className(),['id'=>'tag_id'])->via('blogTag');
}
public function getTagsAsString()
{
$arr = \yii\helpers\ArrayHelper::map($this->tags,'id','name');
return implode (', ',$arr);
}
public function afterFind()
{
$this->tags_array = $this->tags;
}
public function afterSave ($insert, $changedAttributes)
{
parent::afterSave($insert, $changedAttributes);
$arr = \yii\helpers\ArrayHelper::map($this->tags,'id','id');
foreach ($this->tags_array as $one) {
if(!in_array($one,$arr)){
$model = new BlogTag();
$model->blog_id = $this->id;
$model->tag_id = $one;
$model->save();
}
if(isset($arr[$one])) {
unset ($arr[$one]);
}
}
BlogTag::deleteAll(['tag_id'=>$arr]);
}
}
Во втором выдаёт разные ошибки:
