Laravel 5 : multi-model middleware "Owner" -

i want create middleware check if authenticated user owner of item. single model, code easy , :

    <?php namespace app\http\middleware;      use closure;      class owner {          public function handle($request, closure $next)         {             $id = $request->segments()[1]; //get id parameter             $model = model::find($id); // find model db              if(!$item)               return 'not found'; //if item not found              //check if authenticated user owner             if($item->user_id == \auth::id()){                return $next($request);             }else{               return 'not allowed';             }         }     } 

now let's have multiple models (modelx, modely, modelz) , don't want rewrite middleware handle function several times. how 1 inject referenced model in middleware make accomodate multiple models app?

you use middleware parameters route/model binding. lets assume have post resource.

you define route. middleware gets parameter describing resource want check ownership of.

route::get('/post/{post}', ['middleware' => 'owner:post', 'as' => 'post', 'uses' => 'postcontroller@showpost']); 

then bind model in routeserviceprovider.php:

$router->bind('post', function ($value) {    return post::where('id', $value)->firstorfail(); }); 

finally make middleware. important know binding becomes available in request object $request->post. since you're passing name of resource middleware, becomes third parameter in handle method.

public function handle($request, closure $next, $resource) {     if ($request->{$resource}->user_id == \auth::id()) {       return $next($request);     }     return response('not allowed.', 401); } 

i suppose programmatically find resource name, using method resource name , route can different.
