复制具有所有关系的Doctrine对象 [英] Copy a Doctrine object with all relations

问题描述

我正在尝试：

  $ o = Doctrine :: getTable（'Table'） - > Find（x）; 
 $ copy = $ object-> copy（）; 
 $ relations = $ o-> getRelations（）; 
 
 foreach（$ relations as $ name => $ relation）{
 $ copy-> $ relation = $ object-> $ relation-> copy（）; 
} 
 
 $ copy-> save（）; 
  

此代码无效，但我认为它在路上。

解决方案

我从来不会让深层复制功能正常运行。

我手动编码这样一个我的模型的深度拷贝功能

  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 $ questions）
 {
 $ answers = $ question-> Survey_Answers; 
 $ newQuestion = $ question-> copy（）; 
 $ newQuestion-> survey_surveys_id = $ survey-> id; 
 $ newQuestion-> save（）; 
 $ newAnswers = new Doctrine_Collection（Survey_Model_Answer）; 
 
 foreach（$ answer 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（）; 
} 
  

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.

解决方案

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();
}
