Question

Ich bin neu in Doctrine, ich versuche, Slim Framework mit Doctrine zu kombinieren. Ich kann Doctrine mit Slim mit einfachen Abfragen verwenden. Aber ich weiß nicht, wie man eine komplexe Abfrage in Doctrine erstellt.

Ich habe zwei Entity, One Cases und One Cases Translation. Dann habe ich CasesResource und CasesService. Ich möchte einen inneren Join in den CasesService einfügen. Wie kann ich das machen ?

Answer 1

Bevor trete ein Sie Ihre Entitäten Beziehung abbilden sollte. Sie können in Erwägung ziehen, Association Mapping in Doctrine Documentation zu lesen.

class CasesTranslation { 

     /** 
     * One CasesTranslation has One Cases. Mapped here. 
     * @OneToOne(targetEntity="Cases") 
     * @JoinColumn(name="cid", referencedColumnName="id",inversedBy="caseTranslation") 
     */ 
     protected $case; 

     // getter and setter here 
} 

class CasesTranslation { 
     /** 
     * One Cases has One CasesTranslation. Inversed here. 
     * @OneToOne(targetEntity="CasesTranslation",mappedBy="case") 
     */ 
     protected $caseTranslation; 

     // getter and setter here 
} 

in dem Service Also zurück können Sie einfach Fälle von jeder CasesTranslation nennen:

$caseTranslation->getCases(); // return one case 

PS

Es ist ein verbreitete pratice Entitätsname in Einzahl erstellen. Es stellt nur ein einzelnes Register dar.
