安装 stof bundle和原则扩展(树)时出现致命错误

Question

这是问题：我没有成功安装带有交响乐 2.0 的 stof 捆绑包

我如何进行：

我在 deps 文件中添加以下行：

[GedmoDoctrineExtensions]
    git=https://github.com/l3pp4rd/DoctrineExtensions.git
    target=bundles/gedmo-doctrine-extensions
    version=e93fc1e0a0
[StofDoctrineExtensionsBundle]
    git=https://github.com/stof/StofDoctrineExtensionsBundle.git
    target=bundles/Stof/DoctrineExtensions/Bundle
    version=6b2a8c74bd

然后我运行命令

PHP bin/供应商安装 --重新安装

一切都很好。

然后我在相关文件中激活扩展名

# config.yml
stof_doctrine_extensions:
    default_locale: en_US
    orm:
        default:
            tree: true
orm:
    auto_generate_proxy_classes: %kernel.debug%
    auto_mapping: true
    mappings:
        StofDoctrineExtensionsBundle: ~

---

# AppKernel.php    
use SymfonyComponentHttpKernelKernel;
use SymfonyComponentConfigLoaderLoaderInterface;
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            [...]
            new StofDoctrineExtensionsBundleStofDoctrineExtensionsBundle(),
            [...]
        );

---

# autoload.php
use SymfonyComponentClassLoaderUniversalClassLoader;
use DoctrineCommonAnnotationsAnnotationRegistry;
$loader = new UniversalClassLoader();
$loader->registerNamespaces(array(
    'Gedmo'            => __DIR__.'/../vendor/gedmo-doctrine-extensions/lib',
    'Stof'             => __DIR__.'/../vendor/bundles', 
    [...]
    ));

最后，我添加我的实体类别，如本教程 http://gediminasm.org/article/tree-nestedset-behavior-extension-for-doctrine-2#including-extension

<?php
namespace MyprojectMyBundleEntity;
use GedmoMappingAnnotation as Gedmo;
use DoctrineORMMapping as ORM;
/**
 * @GedmoTree(type="nested")
 * @ORMTable(name="Category")
 * use repository for handy tree functions
 * @ORMEntity(repositoryClass="GedmoTreeEntityRepositoryNestedTreeRepository")
 */
class Category
{
    /**
     * @ORMColumn(name="id", type="integer")
     * @ORMId
     * @ORMGeneratedValue
     */
    private $id;
    /**
     * @ORMColumn(name="title", type="string", length=64)
     */
    private $title;
    /**
     * @GedmoTreeLeft
     * @ORMColumn(name="lft", type="integer")
     */
    private $lft;
    /**
     * @GedmoTreeLevel
     * @ORMColumn(name="lvl", type="integer")
     */
    private $lvl;
    /**
     * @GedmoTreeRight
     * @ORMColumn(name="rgt", type="integer")
     */
    private $rgt;
    /**
     * @GedmoTreeRoot
     * @ORMColumn(name="root", type="integer", nullable=true)
     */
    private $root;
    /**
     * @GedmoTreeParent
     * @ORMManyToOne(targetEntity="Category", inversedBy="children")
     * @ORMJoinColumn(name="parent_id", referencedColumnName="id", onDelete="SET NULL")
     */
    private $parent;
    /**
     * @ORMOneToMany(targetEntity="Category", mappedBy="parent")
     * @ORMOrderBy({"lft" = "ASC"})
     */
    private $children;
}

但是当我运行命令php app/console generate：doctrine：entities MyProjectMyBundle：Category时，我有以下错误：

Fatal error: Out of memory (allocated -1227096064) (tried to allocate 261900 bytes) in /home/user/Project/vendor/doctrine/lib/Doctrine/ORM/Mapping/Driver/XmlDriver.php on line 75

有时这个：

Fatal error: Out of memory (allocated -1222901760) (tried to allocate 261900 bytes) in /home/user/Project/vendor/gedmo-doctrine-extensions/lib/Gedmo/Mapping/MappedEventSubscriber.php on line 176

我做错了什么？

Answer 1

我想

说这些错误与Symfony或Doctrine无关。对我来说，这更像是一个PHP配置问题。

您可以尝试增加php.ini文件中的memory_limit值。在大多数情况下，128MB 的内存限制就足够了，但如果您的项目正在处理大量数据，则可能需要更多。

Answer 2

尝试只加载树扩展：

doctrine:
    orm:
        entity_managers:
            default:
                mappings:
                    gedmo_tree:
                       type: annotation
                       prefix: GedmoTreeEntity
                       dir: "%kernel.root_dir%/../vendor/gedmo/doctrine-extensions/lib/Gedmo/Tree/Entity"
                       alias: GedmoTree # this one is optional and will default to the name set for the mapping
                       is_bundle: false

正如文档所说：https://github.com/stof/StofDoctrineExtensionsBundle/blob/master/Resources/doc/index.rst#add-the-extensions-to-your-mapping
