I have three entities wallpost, albums and photos.
When I post photos on my wall, the data goes into all three tables. One record in wallpost, one in album and multiple in photos.
Now when I fetch data using
$wall_post_obj->getAlbum()->getId()
It shows id but when I try to fetch any other info such as
$wall_post_obj->getAlbum()->getName()
It returns NULL.
This happens only when I delete one photo from album.
To get it work I have to re-initialize it using find query. like this: $em->find('\Entities\album',$id);
Extra information:
The $wall_post_obj comes from following query:
$qb_1 = $em->createQueryBuilder();
$q_1 = $qb_1->select('wp, fromUsr.id,
fromUsr.professional_image,
fromUsr.gender,
fromUsr.firstname,
fromUsr.lastname')
->from( '\Entities\wall_post', 'wp' )
->LeftJoin( 'wp.wall_postsFrom_user', 'fromUsr' )
->where( 'wp.id IN (:selected_wp_ids_r)' )
->setParameter( 'selected_wp_ids_r', $selected_wp_ids_r )
->orderBy( 'wp.last_activity_datetime', 'DESC' );
// wallpost Comments join
$q_1->addSelect( 'wall_comments, comment_user' );
$q_1->LeftJoin( 'wp.wall_postsComment', 'wall_comments' );
$q_1->LeftJoin( 'wall_comments.commentsIlook_user', 'comment_user' );
// wallpost Likes join
$q_1->addSelect( 'likes' );
$q_1->LeftJoin( 'wp.wall_postsLikes', 'likes' );
$q_1->LeftJoin( 'likes.likesLiked_by', 'likedByUser' );
$q_1 = $q_1->getQuery()->getResult ();
The code was called in loop like below:
foreach( ... )
{
$wall_post_obj->getAlbum()
}
But accidentally $em->clear() was placed at the end of the loop.
$em->clear() clears the data from your current object. so $em->refresh() will not work.
