我该如何修复“Route [admin.conditions.update]未定义。”错误？

Question

I can't fix this error: Route *[admin.conditions.update]* not defined. I checked some other posts with the same question, but still can't figure it out.

I checked php artisan route:list. For conditions.update the path was :

admin/conditions/{condition} App/http/controllers/ConditionsController@update

The routes in web.php:

Route::group( ['prefix'=>'admin'] , function()
{
    Route::resource('/conditions','conditionsController');

    Route::get('index' , function() 
    {
        return View('admin.index');
    });
});

My edit.blade.php route:

{!! Form::model( $record , ['method'=>'PATCH' , 'route'=>['admin.conditions.update', $record->id] ] ) !!}

Error is:

Route [admin.conditions.update] not defined. (View: C:\wamp64\www\dbsystemesources\views\admin\conditions\edit.blade.php)*

Some following errors:

The reason your route name isn't working is because prefix only works for the url/uri. To prepend to the route names inside a group as well you need to provide an as to the group:

Route::group(['prefix' => 'admin', 'as' => 'admin.'], function () {
    Route::resource('/conditions', 'conditionsController');

    Route::get('index', function () {
        return View('admin.index');
    });
});

Notice the 'as' => 'admin.'. Don't forget the . on the end.
