Duplicate an AR record & re-insert this into the database
Cloning won't work. You need to assign the attributes to a new object:
$obj = Competitions::model()->find('competition_id=:competition_id', array(':competition_id' => $post['competition_id']));$clone = new Competitions;$clone->attributes = $obj->attributes;$clone->save();
If a more generic way of duplicating a Model / ActiveRecord in Yii2 Framework is required, you might use this solution:
$copy = clone $model;$copy->isNewRecord = true;foreach ($model->getPrimaryKey(true) as $field => $value) { unset($copy->{$field});}$copy->save();GitHub issue discussion about duplicate models: https://github.com/yiisoft/yii2/issues/7544#issuecomment-77158479
The answer for my problem although Michiel above helped me out - alternatively if you wouldn't mind adding another answer i'll give you the accepted answer.
foreach($models as $model) { $clone = new Competitions; $clone->attributes = $model->attributes; $clone->competition_id = '123' // custom var i am setting manually. $clone->save(); }
