How to pass custom requests into Interface class?
问题
在app/Repositories/TagCrudRepository.php中，将CreateTagRequest的类型提示更改为FormRequest，以与CrudInterface中的类型提示保持一致。如下所示：
public function store(array $data, FormRequest $request): Tag
{
// ...
}
这将解决错误，使TagCrudRepository中的store方法与CrudInterface中的方法兼容。
英文:
Making Interface class for Crud operations I need in some cases to pass custom requests
in app/Repositories/Interfaces/CrudInterface.php I have :
<?php
use Illuminate\Foundation\Http\FormRequest;
interface CrudInterface
{
public function store(array $data, FormRequest $request): Model;
...
But when in implementation of this class app/Repositories/TagCrudRepository.php I pass CreateTagRequest as parameter :
<?php
namespace App\Repositories;
use App\Http\Requests\CreateTagRequest;
use App\Repositories\Interfaces\CrudInterface;
use Illuminate\Database\Eloquent\Model;
...
use App\Library\TagsSearchResultsIterator;
class TagCrudRepository implements CrudInterface
{
public function store(array $data, CreateTagRequest $request): Tag
{
...
I got error :
Declaration of App\Repositories\TagCrudRepository::store(array $data, App\Http\Requests\CreateTagRequest $request): App\Models\Tag must be compatible with App\Repositories\Interfaces\CrudInterface::store(array $data, Illuminate\Foundat
ion\Http\FormRequest $request): Illuminate\Database\Eloquent\Model
class app/Http/Requests/CreateTagRequest.php extends extends FormRequest class:
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class CreateTagRequest extends FormRequest
{
How this error can be fixed ?

Tag FormRequest 需要匹配接口定义的方法签名，以确保 store() 方法接收 CreateTagRequest 实例而不是 FormRequest 实例。如需实现此目的，你可以更改接口或创建另一个方法。别无他法。
英文:
You can pass instance of CreateTagRequesta at runtime w/o any problems though because it extends FormRequest but method signature must match what interface (contract) defines. If you need to ensure that this particular store() implementation gets instance of CreateTagRequest and not FormRequest, then you either need to change the interface or create another method. There's no other way.
