I have a simple app makes in symfony3. I try to fetch appropriate tags for my entities and I have a problem.
There is a part of my tag entity:
/**
* Tag
*
* @ORM\Table(name="tag")
* @ORM\Entity(repositoryClass="AppBundle\Repository\TagRepository")
*/
class Tag
{
.
.
.
/**
* @ORM\ManyToMany(targetEntity="Note", mappedBy="tags")
*/
private $notes;
...and there is a part of note entity:
/**
* Note
*
* @ORM\Table(name="note")
* @ORM\Entity(repositoryClass="AppBundle\Repository\NoteRepository")
*/
class Note
{
.
.
.
/**
* @ORM\ManyToMany(targetEntity="Tag", inversedBy="notes", cascade={"persist"})
* @ORM\JoinTable(name="notes_tags")
*/
private $tags;
In my repository class I call:
if(!empty($data['tags'])) {
$query->andWhere('n.tags = :tag')->setParameter('tag', 6);
}
...then results is:
[Semantical Error] line 0, col 46 near 'tags = :tag ORDER': Error: Invalid PathExpression. StateFieldPathExpression or SingleValuedAssociationField expected.
I'm really new in Symfony 2 and Doctrine so I need your help.
Firstly, IMHO you need change in class Note inversedBy to "notes". Also be sure your code looks like http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/association-mapping.html#many-to-many-bidirectional
I found a solution, I have to use MEMBER OF clause:
if(!empty($data['tags'])) {
$query->andWhere(':tag MEMBER OF n.tags')->setParameter('tag', $data['tags']);
}
