使用 symfony3、doctrine2 和 stofDoctrineExtensionsBundle 按任意字段对 Gedmo 树进行排序

Sort Gedmo Tree by arbitrary field using symfony3, doctrine2 and stofDoctrineExtensionsBundle

简介

正在设置

为了设置树结构,我使用了 Symfony.com [2] followed by documentation on GitHub [3]. Then I proceeded with tree setup - used tree entity from example [4] and used code in [5] 上的文档来创建树。

我确实设置了名为 FileTree 的树结构(代表目录和文件)。我向树中添加了几个自定义字段:item_nameitem_extensionis_file。删除了 title 因为我有 item_name...

我的 FileTree 实体:

问题

我需要按文件类型对树文件夹中的文件进行排序 - 即:按 item_extension 然后按 item_name。目前 Gedmo Nestedset Treerootlft 排序,如下一个代码块所示。

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

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

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

    return $build_my_tree;
}

遗憾的是添加额外的 ->orderBy('ft.item_extension', 'ASC') 没有产生任何结果...

然后我了解到 有 2 个函数可以帮助我完成这项工作 reorderAllreorder。我尝试了两个,但遗憾的是项目没有改变它们的顺序,它们仍然按 rootlft.

排序

我的代码来自 Upload Listener

$repo_file_tree = $this->entityManager->getRepository('AppBundle:FileTree');
$root_node_id = $repo_file_tree->getFileTreeRootNodeIdByProjectId($selected_node_parent_id);
$root_node = $repo_file_tree->findOneBy(array('id' => $root_node_id));
$repo_file_tree->reorder($root_node, 'item_extension, item_name', 'ASC');
$this->entityManager->flush();

$repo_file_tree = $this->entityManager->getRepository('AppBundle:FileTree');
$repo_file_tree->reorderAll('item_extension, item_name', 'ASC');
$this->entityManager->flush();

问题

如何获取包含 item_extension, item_name 订购的 FileTree 项的数组?

我很高兴以太正确的 Doctrine 查询(最好)或解释包含函数 reorderreorderAll.

的代码块有什么问题

结论

我错过了什么?

请指教

感谢您的时间和知识。

刚刚将我的项目更新为 Symfony v3.2.0

现在我得到错误

Invalid sort options specified: field - item_extension, item_name, direction - ASC
500 Internal Server Error - InvalidArgumentException

使用reorder时使用上述代码。

我不确定它是刚刚发生(升级后)还是 Symfony v3.1.x 也发生过。

无论如何 - 很明显 reorder 确实只使用一个字段来对树枝进行排序。不像我之前尝试的那样有多个字段。

所以答案是:在调用 reorder 函数时不要使用多个排序字段。

$repo_file_tree = $this->entityManager->getRepository('AppBundle:FileTree');
$root_node_id = $repo_file_tree->getFileTreeRootNodeIdByProjectId($selected_node_parent_id);
$root_node = $repo_file_tree->findOneBy(array('id' => $root_node_id));
$repo_file_tree->reorder($root_node, 'item_extension', 'ASC');
$this->entityManager->flush();
