When I clear caches in my Laravel 5.2 project, I see this error message:
[LogicException] Unable to prepare route [panel] for serialization. Uses Closure.
I think that it's related with a route
Route::get('/article/{slug}', 'Front@slug');
associated with a particular method in my controller:
public function slug($slug) {
$article = Article::where('slug',$slug)->first();
$id = $article ->id_article ;
if ( ($article=== null) || (is_null($id)) ) return view('errors/Db');
else return view('detail')->with(array('article'=> $article, 'title'=>'My title - '.$article->title));
}`
In short, from a master view I pass $slug, that is a shortlink to the article, with $slug , which is unique in the database, I identify the record and then I pass it's contents to the detail view.
I didn't have any problem when I wrote the method, infact it worked like a charm, but after I cleaned caches, I get that error and the links in the master view don't show any shortcode.
Where am I doing wrong?
This question is related to
laravel
serialization
routes
The Actual solution of this problem is changing first line in web.php
Just replace Welcome route with following route
Route::view('/', 'welcome');
If still getting same error than you probab
the solustion when we use routes like this:
Route::get('/', function () {
return view('welcome');
});
laravel call them Closure so you cant optimize routes uses as Closures you must route to controller to use php artisan optimize
Check your routes/web.php and routes/api.php
Laravel comes with default route closure in routes/web.php:
Route::get('/', function () {
return view('welcome');
});
and routes/api.php
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
if you remove that then try again to clear route cache.
If someone is still looking for an answer, for me the problem was in routes/web.php file. Example:
Route::get('/', function () {
return view('welcome');
});
It is also Route, so yeah...Just remove it if not needed and you are good to go! You should also follow answers provided from above.
If none of your routes contain closures, but you are still getting this error, please check
routes/api.php
Laravel has a default auth api route in the above file.
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
which can be commented or replaced with a call to controller method if required.
This is definitely a bug.Laravel offers predefined code in routes/api.php
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
which is unabled to be processed by:
php artisan route:cache
This definitely should be fixed by Laravel team.(check the link),
simply if you want to fix it you should replace routes\api.php code with some thing like :
Route::middleware('auth:api')->get('/user', 'UserController@AuthRouteAPI');
and in UserController put this method:
public function AuthRouteAPI(Request $request){
return $request->user();
}
check that your web.php file has this extension
use Illuminate\Support\Facades\Route;
my problem gone fixed by this way.
