Missing required parameters for [Route: admin.news.edit] [URI: admin/about/news/{news}/edit]. in /var/www/html/heincloud/vendor/laravel/framework/src/Illuminate/Routing/Exceptions/UrlGenerationException.php:17

Hi all,

i changed my single Routes to the CRUD Route Route::resource('news' , 'About\NewsController'); Now i when i push the action Button Edit I get the exception above. With my old Route, Route::get('news/edit', 'About\NewsController@update') ->name('news.update'); it worked, so i am confused now. Maybe you can help me.
