Question

我对Laravel很新，说实话 - 这是一个很棒的框架。但是，我对一些嵌套资源有点困惑 - 包括CRUD和它们。

对于我正在使用的路线

Route::resource('startups','StartupsController');
Route::resource('startups.usecases','UsecasesController');

php artisan route：list

|        | GET|HEAD  | admin/startups                                   | admin.startups.index            | App\Http\Controllers\StartupsController@index                               | web,admin,auth:admin |
|        | POST      | admin/startups                                   | admin.startups.store            | App\Http\Controllers\StartupsController@store                               | web,admin,auth:admin |
|        | GET|HEAD  | admin/startups/create                            | admin.startups.create           | App\Http\Controllers\StartupsController@create                              | web,admin,auth:admin |
|        | DELETE    | admin/startups/{startup}                         | admin.startups.destroy          | App\Http\Controllers\StartupsController@destroy                             | web,admin,auth:admin |
|        | GET|HEAD  | admin/startups/{startup}                         | admin.startups.show             | App\Http\Controllers\StartupsController@show                                | web,admin,auth:admin |
|        | PUT|PATCH | admin/startups/{startup}                         | admin.startups.update           | App\Http\Controllers\StartupsController@update                              | web,admin,auth:admin |
|        | GET|HEAD  | admin/startups/{startup}/edit                    | admin.startups.edit             | App\Http\Controllers\StartupsController@edit                                | web,admin,auth:admin |
|        | GET|HEAD  | admin/startups/{startup}/usecases                | admin.startups.usecases.index   | App\Http\Controllers\UsecasesController@index                               | web,admin,auth:admin |
|        | POST      | admin/startups/{startup}/usecases                | admin.startups.usecases.store   | App\Http\Controllers\UsecasesController@store                               | web,admin,auth:admin |
|        | GET|HEAD  | admin/startups/{startup}/usecases/create         | admin.startups.usecases.create  | App\Http\Controllers\UsecasesController@create                              | web,admin,auth:admin |
|        | DELETE    | admin/startups/{startup}/usecases/{usecase}      | admin.startups.usecases.destroy | App\Http\Controllers\UsecasesController@destroy                             | web,admin,auth:admin |
|        | GET|HEAD  | admin/startups/{startup}/usecases/{usecase}      | admin.startups.usecases.show    | App\Http\Controllers\UsecasesController@show                                | web,admin,auth:admin |
|        | PUT|PATCH | admin/startups/{startup}/usecases/{usecase}      | admin.startups.usecases.update  | App\Http\Controllers\UsecasesController@update                              | web,admin,auth:admin |
|        | GET|HEAD  | admin/startups/{startup}/usecases/{usecase}/edit | admin.startups.usecases.edit    | App\Http\Controllers\UsecasesController@edit                                | web,admin,auth:admin |

对于父母，这里称为＆＃34;初创公司＆＃34;，一切都很好，我可以CRUD一切都很好。

对于孩子，这里称为＆＃34; usecases＆＃34;，index，create和store都可以。当我尝试在模板中添加链接到编辑，删除或显示时，我开始得到：缺少[Route：admin.startups.usecases.destroy]所需的参数[URI：admin / startups / {startup} / usecases / {用例}]。

我的索引裁剪文件中的链接：

<li><a href="{{ route('admin.startups.usecases.show',$startup->id, $usecase->id) }}">Show</a></li>

返回该错误。

在我的UsecasesController中

public function show($startup_id, $usecase_id)
    {
        $startups = $startup_id;
        $usecase = Usecase::find($usecase_id);
        return view('admin.startups.usecases.show')
        ->with('usecase', $usecase)
        ->with('startups', $startups);
    }

TLDR：我可以在父母和＃34;初创公司＆＃34;上访问和CRUD一切。我可以为孩子创建和存储，但不能编辑，显示或删除 - 用于＆＃34; usecases＆＃34;。

感谢您的帮助。

您需要将参数作为数组传递：

route('admin.startups.usecases.show', [$startup->id, $usecase->id])

show()方法如下所示：

public function show($startup, $usecase)
{
    ....

嵌套资源：缺少必需参数（laravel）
