如何在laravel-livewire项目中添加L5存储库？

编程问答 2022-08-12

问题描述

在laravel-livewire /项目中，我需要使用存储库。 我发现了图书馆https://github.com/andersao/l5-repository 并查看示例如何将存储库分配给PostsController 

namespace App\Http\Controllers;

use App\PostRepository;

class PostsController extends BaseController {

    protected $repository;

    public function __construct(PostRepository $repository){
        $this->repository = $repository;
    }

    ....
}

我尝试使component相似：

use App\Repositories\Interfaces\FacilityRepositoryInterface;


class Facilities extends Component
{ 
    use WithPagination;

    public $form= [
        'name'=>'','descr'=> '','created_at'=> '','is_reopen'       => false,];

    public $current_facility_id;
    public $filter_name= '';
    public $updateMode = 'browse';

    protected $FacilityRepository;

    public function __construct(FacilityRepositoryInterface $FacilityRepository)
    {
        $this->FacilityRepository = $FacilityRepository;
    }

    public function render()
    {
        $backend_per_page = Settings::getValue('backend_per_page',CheckValueType::cvtInteger,20);

        $this->emit('facility_opened',[ 'mode'=>'browse','id'=>null ] );

        return view('livewire.admin.facilities.container',[
            'facilityDaTarows' => $this->FacilityRepository->filterWithPagination(
                 [
                     'name'=>$this->filter_name,'per_page'=> $backend_per_page
                 ]
            ),'facility_rows_count'=> $this->facility_rows_count
        ]);
    }

其中filterWithPagination是的方法

class FacilityRepository extends BaseRepository implements FacilityRepositoryInterface
{
    private $UserRepository;
    ...
    
I found deFinition of __construct in in vendor/livewire/livewire/src/Component.PHP as :
    public function __construct($id)
    {
        $this->id = $id;

        $this->ensureIdPropertyIsntOverridden();

        $this->initializeTraits();
    }

有一种有效的方法吗？

谢谢！

解决方法

您应该使用mount方法进行依赖项注入

这应该可行

class Facilities extends Component {
  public function mount(FacilityRepositoryInterface $FacilityRepository) {
    $this->FacilityRepository = $FacilityRepository;
  }
}

查看文档：{​​{3}}

,

我也有同样的担忧。我认为livewire当前不支持依赖项注入。您现在可以做的就是将您的存储库注入mount方法。

  public function mount(FacilityRepositoryInterface $FacilityRepository)
    {
        $this->FacilityRepository = $FacilityRepository;
    }
,

如果你的 action 需要任何应该通过 Laravel 的依赖注入容器解析的服务，你可以在任何附加参数之前在 action 的签名中列出它们

public function addTodo(TodoService $todoService,$id,$name)
    {
        ...
    }
