Error: Class …\\Entity\\.. has no association named

问题:

This question is related to my another question: Doctrine2 gives me only first instance of related objects

I came up with bidirectional association to try solve my old issue but now I have another problem.

Schema [EDITED]:

  XYZ\Bundle\CitiesBundle\Entity\Cities:   type: entity   table: cities   fields:     id:       id: true       type: integer       unsigned: false       nullable: false       generator:         strategy: IDENTITY     name:       type: string       length: 50       fixed: false       nullable: false     landarea:       type: decimal       nullable: false     density:       type: integer       unsigned: false       nullable: false     population:       type: integer       unsigned: false       nullable: false   manyToOne:     state:       targetEntity: States       cascade: {  }       inversedBy: cities       joinColumn:         state_id:           referencedColumnName: id   lifecycleCallbacks: {  } 

Entities:

class Cities {     //other vars      /**      * @var XYZ\Bundle\CitiesBundle\Entity\States      */     private $state;      //other get/set          /**      * Set state      *      * @param XYZ\Bundle\CitiesBundle\Entity\States $state      */     public function setState(\XYZ\Bundle\CitiesBundle\Entity\States $state)     {         $this->state = $state;     }      /**      * Get state      *      * @return XYZ\Bundle\CitiesBundle\Entity\States       */     public function getState()     {         return $this->state;     } }  class States {     //other vars and get/set      private $cities;      public function __construct()     {         $this->cities = new \Doctrine\Common\Collections\ArrayCollection();     }      /**      * Add cities      *      * @param XYZ\Bundle\CitiesBundle\Entity\Cities $cities      */     public function addCities(\XYZ\Bundle\CitiesBundle\Entity\Cities $cities)     {         $this->cities[] = $cities;     }      /**      * Get cities      *      * @return Doctrine\Common\Collections\Collection       */     public function getCities()     {         return $this->cities;     } } 

QueryBuilder usage:

    $query = $em->createQueryBuilder()                 ->select('c','s')                 ->from('CitiesBundle:Cities', 'c')                 ->innerJoin('c.state', 's')                 ->orderBy('c.population', 'DESC')                 ->setMaxResults(10)                 ->getQuery();   

and an error is:

[Semantical Error] line 0, col 58 near 's ORDER BY c.population': Error: Class XYZ\Bundle\CitiesBundle\Entity\Cities has no association named state

generated DQL:

SELECT c, s FROM CitiesBundle:Cities c INNER JOIN c.state s ORDER BY c.population DESC

shame :(

Could someone help me solve my issue?

[EDIT]

I edited cities schema, now error is:

Notice: Undefined index: name in /home/marek/devel/sf2/cities/vendor/doctrine/lib/Doctrine/ORM/Mapping/Driver/YamlDriver.php line 473

回答1:

I'm sure joinColumns: (notice the plural) is only used in Many-To-Many relation. In other relations you should use joinColumn.

In Cities XML, try putting:

joinColumn:     name: state_id     referencedColumnName: id 

other than that try renaming 'ManyToOne' to 'manyToOne' in your XML but I doubt that case is the issue here...

Hope this helps...

回答2:

Note that when using Symfony, it will look at mapping YAML files first and ignore your entity annotations. I spent ages changing my annotations whilst all the time it was loading the YAML mapping file.
