问题 I have a model with two values that has to be unique together. Yii2 has a validation rule for this: [['object_id', 'created_by'], 'unique', 'targetAttribute' => ['object_id', 'created_by']] The created_by attribute is generated with blameable behavior: public function behaviors() { return [ 'blameable' => [ 'class' => BlameableBehavior::className(), 'createdByAttribute' => 'created_by', 'updatedByAttribute' => 'updated_by', ], ]; } The validating is done before the behavior input is stored in
