如何从 di 依赖注入容器上下文在 nette 中自动装配/自动装配服务

Question

How to autowire nette services from the container, to be accessible to be used inside presenters ( controllers ) or models,etc?

Answer 1

To autowire services in Nette to be easily retrievable, used, they must be registered in a config.neon config, or must be those preset by default by framework, in multiple ways:

• specifying and passing by interface, class type in the constructor

    use App\Model; // or use App\Model\ArticleRepository;
    public function __construct(
        Model\ArticlesRepository $articlesRepository,
     ...
    )
    {
        $this->articlesRepository = $articlesRepository;

• autowiring via a @inject tag attribute annotation

    /** @var  \Nette\Http\Request @inject */ // however , this one is just example, the request service is already available in the presenters via $this->request attribute
    public $request;
