Sonata with Symfony3.4 - 依赖注入（正确的 Sonata 管理服务声明）

Question

我正在尝试在我的 symphony 3.4 项目上安装 Sonata (sonata-project/admin-bundle)。

不幸的是，我在添加第一个服务时出错了。

services.yaml :

    admin.carrier:
    class: App\Admin\CarrierAdmin
    arguments: [~, App\Entity\Carrier, ~]
    tags:
        - { name: sonata.admin, manager_type: orm, label: Carrier }
    public: true

访问 http://localhost/admin/dashboard 时出现的错误：

1) FatalThrowableError

Type error: strlen() expects parameter 1 to be string, null given
in AddDependencyCallsCompilerPass.php (line 401)
at strlen(null)in AddDependencyCallsCompilerPass.php (line 401)
at AddDependencyCallsCompilerPass->replaceDefaultArguments(array('admin.carrier', 'SonataAdminBundle:CRUD'), object(Definition), null)in AddDependencyCallsCompilerPass.php (line 67)
at AddDependencyCallsCompilerPass->process(object(ContainerBuilder))in Compiler.php (line 141)
at Compiler->compile(object(ContainerBuilder))in ContainerBuilder.php (line 753)
at ContainerBuilder->compile()in Kernel.php (line 634)
at Kernel->initializeContainer()in Kernel.php (line 137)
at Kernel->boot()in Kernel.php (line 197)
at Kernel->handle(object(Request))in index.php (line 25)

有谁能帮帮我吗？

首先，将应用前缀添加到您的管理服务是个好主意。但是你在声明 CRUD 控制器时犯了错误。第三个参数 - 是此管理服务的 CRUD 控制器。因此，您应该使用默认值：SonataAdminBundle:CRUD

app.admin.carrier:
    class: App\Admin\CarrierAdmin
    arguments: [~, App\Entity\Carrier, SonataAdminBundle:CRUD]
    tags:
        - { name: sonata.admin, manager_type: orm, group: 'carrier', label_catalogue: "admin", label: 'carrier' }
