没有为 class App\Entity\Category 定义实体管理器

Question

我遵循了 symfony (https://symfony.com/doc/master/bundles/SonataAdminBundle/getting_started/creating_an_admin.html) 的入门教程，并且一切正常（Category 和 BlogPost）

之后我做了一些修改来处理 SonataUserBundle 并让这个后端只为管理员保护。

我以某种方式做到了这一点，只有在以管理员角色登录时我才能访问管理员。

但现在当我尝试继续分类或 BlogPost 时，出现错误：

No entity manager defined for class App\Entity\Category

或

No entity manager defined for class App\Entity\BlogPost

我可能在安装用户管理时搞砸了一些东西，但我看不到它在哪里。

services.yaml

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

        - { name: sonata.admin, manager_type: orm, label: 'Blog Post' }

如果您需要更安静的代码，请告诉我，我看不到也不明白哪里出了问题。

编辑：添加 doctrine.yaml

doctrine:
    dbal:
        # configure these for your database server
        driver: 'pdo_mysql'
        server_version: '5.7'
        charset: utf8mb4
        default_table_options:
            charset: utf8mb4
            collate: utf8mb4_unicode_ci
        types:
            json: Sonata\Doctrine\Types\JsonType

        url: '%env(resolve:DATABASE_URL)%'
    orm:
        auto_generate_proxy_classes: true
        entity_managers:
            default:
                mappings:
                    SonataUserBundle: ~
                    FOSUserBundle: ~
                    ApplicationSonataUserBundle: ~

Answer 1

您似乎需要为 App

添加映射

# config/packages/doctrine.yaml
doctrine:
    ...
    orm:
        ...
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity'
                alias: App

没有为 class App\Entity\Category 定义实体管理器

No entity manager defined for class App\Entity\Category
