Php 未定义的可变Laravel路由

我有很酷的模型和控制器。该函数不输出变量。我在路由中注册了路径，但仍然给出了一个错误。写入未找到

footers

变量

网

控制器

 public function footerAll(){
    return view('layouts.app', ['footers' => System::all()]);             
 }

布局/app.blade.php

    @forelse ($footers as $footer)
                    <div>
                        <h1>{{$footer->marketing}}</h1>
                    </div>
                 @empty
                 <h2 class="text-center">Epmty</h2>
    @endforelse

web.php

    Route::get('/blog/category/{slug?}', 'BlogController@category')->name('category');
  Route::get('/blog/article/{slug?}', 'BlogController@article')->name('article');
 Route::group(['prefix'=>'admin', 'namespace'=>'Admin', 'middleware'=> ['auth']], function(){

  Route::resource('/category', 'CategoryController', ['as'=>'admin']);
  Route::resource('/article', 'ArticleController', ['as'=>'admin']);
  Route::group(['prefix' => 'user_managment', 'namespace' => 'UserManagment'], function() {
  Route::resource('/user', 'UserController', ['as' =>'admin.user_managment']);
  });
Route::group(['middleware' => 'admin'], function() {
    Route::get('/', 'DashboardController@dashboard')->name('admin.index');
});
});
Route::get('/', 'BlogController@articlesAll', function () {
    return view('blog.home');
});

Route::get('/app', 'SystemController@footerAll')->name('footers');

路由：：post（'/comment/store'，'CommentController@store'）->name（'comment.add'）

我认为您必须在另一个视图中包含您的一个视图。否则，您将只删除其中一个。如果在

应用程序之前删除
/
，会发生什么？如
Route:：get（'app'，'SystemController@footerAll'）->名称（'页脚'）@user3532758 get me错误页脚不正确found@porloscerrosψ我如何才能做到这一点？我需要得到这个变量你如何共享路由文件的内容？或者，您可以发布错误的屏幕截图。您是否有其他链接到
应用程序的路由？
 Route::get('/', 'BlogController@articlesAll', function () {
        return view('blog.home');
    });

    Route::get('/blog/category/{slug?}', 'BlogController@category')->name('category');
  Route::get('/blog/article/{slug?}', 'BlogController@article')->name('article');
 Route::group(['prefix'=>'admin', 'namespace'=>'Admin', 'middleware'=> ['auth']], function(){

  Route::resource('/category', 'CategoryController', ['as'=>'admin']);
  Route::resource('/article', 'ArticleController', ['as'=>'admin']);
  Route::group(['prefix' => 'user_managment', 'namespace' => 'UserManagment'], function() {
  Route::resource('/user', 'UserController', ['as' =>'admin.user_managment']);
  });
Route::group(['middleware' => 'admin'], function() {
    Route::get('/', 'DashboardController@dashboard')->name('admin.index');
});
});
Route::get('/', 'BlogController@articlesAll', function () {
    return view('blog.home');
});

Route::get('/app', 'SystemController@footerAll')->name('footers');

Auth::routes();

//Route::get('/home', 'HomeController@index')->name('home'); 

Route::get('/home', 'HomeController@getUser')->name('users');
