SonataAdmin 安装问题

Question

我试图在我的 Symfony 项目上安装 SonataAdmin，但是在文档的第 2 部分末尾，当我试图继续“http://localhost:8000/admin/”时，我遇到了一个错误："You have requested a non-existent service "admin.category" in .（从 "C:\wamp64\www\Sonata/app/config\routing.yml" 导入）。确保有支持 "sonata_admin" 类型的加载程序。"

我不知道为什么，我给了我所有的参数代码，也许它可以帮助你理解我的问题。

参数： #parameter_name: 值

服务：

# default configuration for services in *this* file
_defaults:
    # automatically injects dependencies in your services
    autowire: true
    # automatically registers your services as commands, event subscribers, etc.
    autoconfigure: true
    # this means you cannot fetch services directly from the container via $container->get()
    # if you need to do this, you can override this setting on individual services
    public: false

admin.category:
    class: AppBundle\Admin\CategoryAdmin
    arguments: [~, AppBundle\Entity\Category, ~]
    tags:
        - { name: sonata.admin, manager_type: orm, label: Category }


# makes classes in src/AppBundle available to be used as services
# this creates a service per class whose id is the fully-qualified class name
AppBundle\:
    resource: '../../src/AppBundle/*'
    # you can exclude directories or files
    # but if a service is unused, it's removed anyway
    exclude: '../../src/AppBundle/{Entity,Repository,Tests}'

# controllers are imported separately to make sure they're public
# and have a tag that allows actions to type-hint services
AppBundle\Controller\:
    resource: '../../src/AppBundle/Controller'
    public: true
    tags: ['controller.service_arguments']

# add more services, or override services that need manual wiring
# AppBundle\Service\ExampleService:
#     arguments:
#         $someArgument: 'some_value'

缩进有问题我给你加一张这个文件的图片。 Service code

Answer 1

我认为您将 category.admin 服务写在 Sonata/app/config/routing.yml 中是错误的，而不是 Sonata/src/YourAdminBundle/Resources/config/services.yml

Answer 2

奏鸣曲管理服务必须 public。在您的配置中，默认值为 public: false，这就是您收到此错误的原因。

所以你有两个选择：

为您的管理服务指定 public: true（在您的示例文件中）
或者更好的方法：创建一个新的服务文件（例如 admin.yml），您不使用这些默认值（_defaults 键和 public: false）。 Public 默认为 true，因此您不必通过 _defaults 指定。在这种情况下，您必须在 config.yml 中导入新文件才能工作：

app/config.yml

的顶部

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: services.yml }
    - { resource: admin.yml }

app/admin.yml内容：

services:
    admin.category:
        class: AppBundle\Admin\CategoryAdmin
        arguments: [~, AppBundle\Entity\Category, ~]
        tags:
            - { name: sonata.admin, manager_type: orm, label: Category }

Answer 3

运行终端上的这个命令。因为您可能错过了安装

php composer.phar require sonata-project/doctrine-orm-admin-bundle

在此之后将下面的代码添加到您的 AppKernel.php

// app/AppKernel.php

public function registerBundles()
{
    return array(
        // ...
        // set up basic sonata requirements
        // ...
        new Sonata\DoctrineORMAdminBundle\SonataDoctrineORMAdminBundle(),
        // ...
    );
}
