使用 symfony4、doctrine2 和 stofDoctrineExtensionsBundle 按任意字段对 Gedmo 树进行排序

Question

Introduction

For my personal project i am using:

• Windows 10 Pro
• XAMPP with PHP v7.2.14
• Postgres v10.6
• Symfony v4.2.4

• Doctrine v2.6.3

• StofDoctrineExtensionsBundle in order to manage Tree structure.

Setting up

I did setup the tree structure (that represents directories and files) called FileTree . I added several custom fields to the tree: item_name , item_extension , item_sort_value and is_file .

Problem

I can not get folders and files sorted by field item_sort_value in the fileTree!

At the same time i can sort items (as is needed) when only retrieving files inside custom filder.

My CODE

Retrieving (full size) folder file tree

public function getFileTreeNodeArray($file_tree_root_id): array
{
    $em = $this->getEntityManager();

    $query = $em
        ->createQueryBuilder()
        ->select('ft')
        ->from(FileTree::class, 'ft')
        ->where('ft.root = :root_id')
        ->setParameter('root_id', $file_tree_root_id)
        ->orderBy('ft.root, ft.lft', 'ASC')
        //->addOrderBy('ft.itemSortValue', 'ASC')
        ->getQuery();

    $query->setHint(\Doctrine\ORM\Query::HINT_INCLUDE_META_COLUMNS, true);

    return $query->getArrayResult();
}

Retrieving files in the folder

public function getFileTreeNodeContentFilesByUploaderArray($file_tree_node_id, $user_id): array
{
    $em = $this->getEntityManager();

    $is_file = true;
    $query = $em
        ->createQueryBuilder()
        ->select('ft')
        ->from(FileTree::class, 'ft')
        ->where('ft.parent = :file_tree_node_id')
        ->andWhere('ft.isFile = :is_file')
        ->andWhere('ft.uploader = :user_id')
        ->setParameter('file_tree_node_id', $file_tree_node_id)
        ->setParameter('is_file', $is_file)
        ->setParameter('user_id', $user_id)
        ->orderBy('ft.itemSortValue', 'ASC')
        ->getQuery();

    $query->setHint(\Doctrine\ORM\Query::HINT_INCLUDE_META_COLUMNS, true);

    return $query->getArrayResult();
}

What i tried

I tried to use reorder and reorderAll , but "to no avail".

An example

public function reorderFileTreeBranch($parent_id): void
{
    $repo_file_tree = $this->entityManager->getRepository(FileTree::class);

    $branch_node = $repo_file_tree->findOneBy(['id' => $parent_id]);
    $repo_file_tree->reorder($branch_node, 'item_sort_value', 'ASC');
    $this->entityManager->flush();
}

i can see many additional SQL queries (whenever i use reorder or reorderAll ) in the Symfony profiler , so something is definitely going on, but after that - items are sorted the same in the tree...

Conclusion

Am i doing something wrong?

Ideas and answers are welcome!

Answer 1

Well, after many tries and fails i managed to got it working as expected. Turned out that reorder in NestedTreeRepositoryTrait did not return true on success... I fixed it - and so - now ordering woks as intended.
