What a strange behavior after migration?

Created migration
public function safeUp()
 public function safeDown()

added a field to the validation of the model

public function rules()
 return [
 [['title', 'description','time','url'], 'required'],
 [['description'], 'string'],
 [['created_at', 'update_at'], 'safe'],
 [['title', 'image','time','url'], 'string', 'max' => 255],

well, in the attributes
public function attributeLabels()
 return [
 'id' => 'ID',
 'title' => Yii::t('app','Name'),
 'description' => Yii::t('app','Description'),
 'image' => Yii::t('app','Picture'),
 'time' => Yii::t('app','cooking Time'),
 'created_at' => Yii::t('app','creation date'),
 'update_at' => Yii::t('app','change date'),

trying to save the form (without fields in the form) get the following error
Fatal error: Uncaught yii\base\UnknownPropertyException: Getting unknown property: common\models\Recipes::url
Migration applied. What is the error ?

Clean the cache of the framework. The runtime folder
Handles ? Or is there some other possibility ? - vergie.Jerde commented on June 10th 19 at 15:10

You have enabled the cache database schemas.

Can be disabled in kafige component database
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=localhost;dbname=back_import',
'enableSchemaCache' => false

Or you can refresh the schema cache in a live migration
