__construct()必须实现接口错误

Question

我使用symfony2和sonataadminbundle，sonatamediabundle和sonatacclassification bundle

现在我想为管理面板进行CUSTMIZE设置，但是我有此错误。

 [SymfonyComponentConfigExceptionFileLoaderLoadException]                 
  Catchable Fatal Error: Argument 5 passed to SonataMediaBundleAdminBaseMe  
  diaAdmin::__construct() must implement interface SonataClassificationBundl  
  eModelCategoryManagerInterface, none given, called in /Users/whitebear/Codin  
  gWorks/httproot/myapp/app/cache/de_/appDevDebugProjectContaine_.php on l  
  ine 9494 and defined in . (which is being imported from "/Users/whitebear/Codi  
  ngWorks/httproot/myapp/app/config/routing.yml").       

我所做的是两件事。

制作依赖性文件

application/sonata/mediabundle/depentencyInjection/applicationsOnatamediaextension.php

  <?php
namespace ApplicationSonataMediaBundleDependencyInjection;
use SymfonyComponentDependencyInjectionContainerBuilder;
use SymfonyComponentConfigFileLocator;
use SymfonyComponentHttpKernelDependencyInjectionExtension;
use SymfonyComponentDependencyInjectionLoader;
/**
 * This is the class that loads and manages your bundle configuration
 *
 * To learn more see {@link http://symfony.com/doc/current/cookbook/bundles/extension.html}
 */
class ApplicationSonataMediaExtension extends Extension
{
    /**
     * {@inheritDoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $loader = new LoaderYamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('services.yml');
    }
}

然后为admin提供了服务

application/sonata/mediabundle/resources/config/services.yml

#Disable gallery & media menu from admin panel
services:
    sonata.media.admin.media:
        class: %sonata.media.admin.media.class%
        tags:
            - { name: sonata.admin, manager_type: orm, show_in_dashboard: false, label_catalogue: %sonata.media.admin.media.translation_domain% , label_translator_strategy: sonata.admin.label.strategy.underscore }
        arguments:
            - ~
            - %sonata.media.admin.media.entity%
            - %sonata.media.admin.media.controller%
            - "@sonata.media.pool"
            - %sonata.classification.manager.category% # add here.
        calls:
            - [setModelManager, ["@sonata.media.admin.media.manager"]]
            - [setTranslationDomain, [%sonata.media.admin.media.translation_domain%]]
            - [setTemplates, [{ inner_list_row: SonataMediaBundle:MediaAdmin:inner_row_media.html.twig , base_list_field: SonataAdminBundle:CRUD:base_list_flat_field.html.twig , list: SonataMediaBundle:MediaAdmin:list.html.twig , edit: SonataMediaBundle:MediaAdmin:edit.html.twig }]]
    sonata.media.admin.gallery:
        class: %sonata.media.admin.gallery.class%
        tags:
            - { name: sonata.admin, manager_type: orm, show_in_dashboard: false, label_catalogue: %sonata.media.admin.media.translation_domain% , label_translator_strategy: sonata.admin.label.strategy.underscore }
        arguments:
            - ~
            - %sonata.media.admin.gallery.entity%
            - %sonata.media.admin.gallery.controller%
            - "@sonata.media.pool"
        calls:
            - [setTranslationDomain, [%sonata.media.admin.media.translation_domain%]]
            - [setTemplates, [{ list: SonataMediaBundle:GalleryAdmin:list.html.twig }]]

sonata MediaBundle admin basemediaadmin

abstract class BaseMediaAdmin extends AbstractAdmin
{
    /**
     * @var Pool
     */
    protected $pool;
    /**
     * @var CategoryManagerInterface
     */
    protected $categoryManager;
    /**
     * @param string                   $code
     * @param string                   $class
     * @param string                   $baseControllerName
     * @param Pool                     $pool
     * @param CategoryManagerInterface $categoryManager
     */
    public function __construct($code, $class, $baseControllerName, Pool $pool, CategoryManagerInterface $categoryManager)
    {
        parent::__construct($code, $class, $baseControllerName);
        $this->pool = $pool;
        $this->categoryManager = $categoryManager;
    }

感谢@mdma我发现我必须将第5个参数作为基本构造构架的类别managerinterface。

。

然后我更新了service.yml，但我有这样的错误。

 [SymfonyComponentDependencyInjectionExceptionParameterNotFoundException]  
  The service "sonata.media.admin.media" has a dependency on a non-existent p   
  arameter "sonata.classification.manager.category". Did you mean one of thes   
  e: "sonata.classification.manager.category.class", "sonata.classification.m   
  anager.tag.class", "sonata.classification.manager.context.class", "sonata.c   
  lassification.manager.tag.entity", "sonata.classification.manager.category.   
  entity", "sonata.classification.manager.context.entity", "sonata.classifica   
  tion.admin.category.class"?

它解决了。我更改了这个句子inservices.yml

- %sonata.classification.manager.category% to "@sonata.classification.manager.category"

Answer 1

错误说：sonata mediabundle admin baseemediaadmin :: __ construct（）

中不存在参数5

因此，请查看您的sonata.media.admin.media服务配置中的参数。只有4个参数。您需要添加第五。

在Bundle Config（https://github.com/sonata-project/sonatamediabundle/blob/master/master/resources/config/doctrine_orm_admin.xml）中，有5个参数：

<argument/>
<argument>%sonata.media.admin.media.entity%</argument>
<argument>%sonata.media.admin.media.controller%</argument>
<argument type="service" id="sonata.media.pool"/>
<argument type="service" id="sonata.media.manager.category" on-invalid="null"/>

所以，我认为您可以将 @sonata.media.manager.category添加为第五参数。
