Copy a Doctrine object with all relations

doctrine, orm, php, symfony-1.4, symfony1

Solution

I never could get the deep copy function to operate correctly.

I manually coded a deep copy function for one of my models like this

public function copyAndSave ()
{
    $filters = array('id', 'created');

    $survey = $this->copy();

    $survey->Survey_Entries = new Doctrine_Collection("Survey_Model_Entry");
    $survey->Assignment_Assignments = new Doctrine_Collection("Assignment_Model_Assignment");
    $survey->Survey_Questions = new Doctrine_Collection("Survey_Model_Question");

    $survey->save();

    foreach ($this->Survey_Questions as $question)
    {
        $answers = $question->Survey_Answers;
        $newQuestion = $question->copy();
        $newQuestion->survey_surveys_id = $survey->id;
        $newQuestion->save();
        $newAnswers = new Doctrine_Collection("Survey_Model_Answer");

        foreach($answers as $answer)
        {
            $answer = $answer->copy();
            $answer->save();
            $answer->survey_questions_id = $newQuestion->id;
            $newAnswers->add($answer);
        }
        $newQuestion->Survey_Answers = $newAnswers;

        $survey->Survey_Questions->add($newQuestion);
    }
    return $survey->save();
}

Problem

I want to copy a record with all his relations. I'm trying with: ``` $o = Doctrine::getTable('Table')->Find(x); $copy = $object->copy(); $relations = $o->getRelations(); foreach ($relations as $name => $relation) { $copy->$relation = $object->$relation->copy(); } $copy->save(); ``` This code doesn't works, but I think it's on the way.
