In general, there is an attribute title for example. When you insert a record (action create), it is set to a value, for example, "Header". The question is how to prevent it from changing during the update? Those. That at action update it was not affected at all?
Value is assigned in beforeSave
public function beforeSave($insert) { if ( parent::beforeSave($insert) ) { echo 'insert'; exit(); $this->title = HtmlPurifier::process( $this->title ); } else { echo 'update'; exit(); } } I understand the problem is that it always returns 'insert'
