Symfony3 - Left Join funktioniert nicht richtig

Versuchen Sie, dieses Problem mit Join in Symfony3 zu lösen.Symfony3 - Left Join funktioniert nicht richtig

Irgendwie ist die resultset hat Werte gemischt, das heißt

ID Exploit Author 
ID Author Author

Sie bitte den beiliegenden Screenshot sehen.

OpenX sollte Autor Metasploit haben und die zweite Reihe nicht dort sein sollte.

Haben Sie diesen Code in der Steuerung:

public function indexAction() 
    { 
     $exploits = $this->getDoctrine() 
       ->getRepository('AppBundle:Exploit')->createQueryBuilder('e') 
      ->add('select', 'a,e') 
      ->add('from', 'AppBundle:Exploit e') 
      ->leftJoin('AppBundle:Author', 'a') 
      ->where('e.author = a.id') 
      ->getQuery() 
      ->getResult(); 

     return $this->render('exploit/index.html.twig', array(
      'exploits' => $exploits 
     )); 
    }

Diese Ansicht:

<tbody> 
      {% for exploit in exploits %} 
      <tr> 
       <th scope="row">{{ exploit.id }}</th> 
       <td>{{ exploit.name }}</td> 

       <td> {{ exploit.author }} </td> 

       <td> 
        <a href="/details/{{ exploit.id }}" class="btn btn-success">View</a> 
        <a href="/edit/{{ exploit.id }}" class="btn btn-default">Edit</a> 
        <a href="/delete/{{ exploit.id }}" class="btn btn-danger">Delete</a> 
       </td> 
      </tr> 
      {% endfor %}

Und diese Instanzen:

Try this:

->leftJoin('AppBundle:Author', 'a', "WITH", "e.author = a.id")

Statt dessen:

->leftJoin('AppBundle:Author', 'a') 
      ->where('e.author = a.id')

Danke! Versucht das, aber leider ist die Ausgabe gleich .... hat nicht geholfen :( –

Versuchen

public function indexAction() 
{ 
    $exploits = $this->getDoctrine() 
     ->getRepository('AppBundle:Exploit')->createQueryBuilder('e') 
     ->leftjoin('e.author','a') 
     ->addSelect('a') 
     ->getQuery() 
     ->getResult(); 

    return $this->render('exploit/index.html.twig', array(
     'exploits' => $exploits 
    )); 
}

und in der Ansicht

<tbody> 
      {% for exploit in exploits %} 
      <tr> 
       <th scope="row">{{ exploit.id }}</th> 
       <td>{{ exploit.name }}</td> 

       <td> {{ exploit.author.name }} </td> 

       <td> 
        <a href="/details/{{ exploit.id }}" class="btn btn-success">View</a> 
        <a href="/edit/{{ exploit.id }}" class="btn btn-default">Edit</a>

Leider bekomme ich diesen Fehler: [2/2] QueryException: [Semantischer Fehler] Zeile 0, Spalte 63 in der Nähe von 'a': Fehler: Klasse AppBundle \ Entity \ Exploit hat keine Assoziation mit dem Namen author –

Nun, weil Sie eine unidirektionale OneToOne-Beziehung vom Autor zu Exploit haben Wenn möglich verschieben Sie die Relationsdefinition in Exploit-> Autorfeld oder machen Sie die Relation bidirektional (besser um möglichst bidirektionale Relationen zu vermeiden)) – Asha

Danke, Sie scheinen sich in diesem Bereich auskennen zu können, vielleicht können Sie mich bei meiner anderen, verwandten Frage sehen Ich habe meine Entitäten überarbeitet, siehe Update 3: in dieser Frage: https://stackoverflow.com/questions/46764888/symfony3-showing-one-to-many-relations-in-view .... aber irgendwie funktioniert es immer noch nicht –
