I have a relationship between post and tag in post show page I'm trying to display post related to the post show content but excluding the main show content it's not working and I'm not getting error.
class PostShow extends Component
{
public $post;
public $body;
public $slug;
public $comment;
public function mount(Post $post) {
$this->post = $post;
}
protected $rules = [
'comment' => 'string|required|min:3|max:5000',
];
protected $listeners = [
'commentWasAdded'
];
public function commentWasAdded() {
$this->post->refresh();
}
public function render() {
$post = Post::where('slug', '=', $slug)->first();
$related = Post::whereHas('tags', function ($q) use ($post) {
return $q->whereIn('name', $post->tags->pluck('name'));
})
->where('id', '!=', $post->id) // So you won't fetch same post
->get();
return view('livewire.post-show',[
'related' => $related,
]);
}
}
My app was working fine until I wanted to replace my "get" routes with a single "resource" to be able to include a delete function. I remind you that I am a beginner in laravel so it is surely due to the fact that I can not be able to make a "resource" route.
This is my code :
Route::get('/', function(){
return view('front.pages.homepage');
})->name('homepage');
Route::get('/garages', [GarageController::class, 'index'])->name('garage.index');
Route::get('/garages/{garage}', [GarageController::class, 'show'])->name('garage.show');
Route::get('/garages_create', [GarageController::class, 'create'])->name('garage.create');
Route::post('/garages_create', [GarageController::class, 'garage_create'])->name('garage_create');
Route::resource('cars', [CarController::class]);
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Car;
use App\Models\Garage;
class CarController extends Controller
{
public function index()
{
$list = Car::paginate(10);
return view('cars', [
'list' => $list
]);
}
public function store()
{
$garages = Garage::orderBy('name')->get();
return view('carCreate/carCreate', [
'garages' => $garages,
]);
}
public function create(Request $request)
{
{
$request->validate([
'name' => 'required',
'release_year' => 'required',
'garage_id' => 'required', 'exists:garage_id'
]);
$car = new Car();
$car->name = $request->name;
$car->release_year = $request->release_year;
$car->garage_id = $request->garage_id;
$car->save();
return redirect('/cars');
}
}
public function show(Car $car)
{
return view('carShow/carShow', compact('car'));
}
public function edit($id)
{
//
}
public function update(Request $request, $id)
{
//
}
public function destroy($id)
{
//
}
}
And my error is : ErrorException

I've been stuck with Broadcasting on private channel in authentication part. What I have done is, I made custom authEndpoint in Echo server
"authEndpoint": "/broadcastAuth",
Controller:
public function broadcastAuth(Request $request){
$channel = $this->normalizeChannelName($request->channel_name);
$broadcaster = new CustomBroadcaster();
$channelAuth = $broadcaster->verifyUserCanAccessChannel($request, $channel);
if($channelAuth){
return true;
}
return response()->json([
'message' => 'Not allowed'
], 403);
}
I have made a custom broadcaster class that extends Illuminate\Broadcasting\Broadcasters\Broadcaster
so that I can override verifyUserCanAccessChannel method
My verifyUserCanAccessChannel method:
public function verifyUserCanAccessChannel($request, $channel)
{
Log::info($this->channels);
foreach ($this->channels as $pattern => $callback) {
if (! $this->channelNameMatchesPattern($channel, $pattern)) {
continue;
}
$parameters = $this->extractAuthParameters($pattern, $channel, $callback);
$handler = $this->normalizeChannelHandlerToCallable($callback);
if ($result = $handler($request->user(), ...$parameters)) {
return $this->validAuthenticationResponse($request, $result);
}
}
throw new AccessDeniedHttpException;
}
Here I have logged $this->channels to get the registered channels from routes/channel.php
But the result is empty.
Here is my BroadcastServiceProvider:
public function boot()
{
require base_path('routes/channels.php');
}
Here is my channel.php:
Broadcast::channel('App.User.{id}', function ($user, $id) {
return (int) $user->id === (int) $id;
});
Broadcast::channel('post-comment.{id}', function ($user, $id){
\Illuminate\Support\Facades\Log::info($user);
return true;
});
And I have uncommented both in config/app.php
Illuminate\Broadcasting\BroadcastServiceProvider::class,
App\Providers\BroadcastServiceProvider::class,
What could be the mistake here. Please help me figure this out.
Thank you in advance.
I going to do massage notification, I already make the notifications steps,
but gives me this error
when I do dd($notifiable); I found all data
Undefined index: user_id OR
Undefined index: name
public function store(Request $request)
{
$chating=new chats();
$chating->chat = $request->input('chat');
$chating->user_id = Auth::id();
$chating->employee_id = $request->input('employeeid');
$chating->save();
$user_id=$request->input('employeeid');
auth()->user()->notify(new SendMassages($user_id));
return redirect()->back();
}

}
}
It seems that you have problem with encapsulation in your code. First you have to make the property of your model into public if you want the quick and not-safe way but if you want the OOP way, You must write setters to do that logic for you.
First and not-safe approach :
class YourModel {
public $user_id;
.
.
.
}
The OOP way:
Class {
public function setUserId(int $userId)
{
$this->user_id = $userId;
}
.
.
.
}
if you are willing to get the exact answer please copy your controllerclass and model in here.
When creating a simple one-to-one relationship in Laravel 5.5, $person->user is returning a null value whenever I use the method/relation name user. If I change the name to foo, User, or login the code seems to work fine. This is the second project I've had this same issue on. Can anyone see what I'm doing wrong?
In Person model:
public function user() {
return $this->belongsTo(User::class, 'user_id', 'id');
}
public function foo() {
return $this->belongsTo(User::class, 'user_id', 'id');
}
public function getUser() {
if ($this->user_id) {
return User::find($this->user_id);
} else {
return null;
}
}
In PersonTest:
$user = factory(User::class)->create();
$person = factory(Person::class)->create(['user_id' => $user->id]);
// This works
$this->assertTrue( $person->getUser()->is($user) );
// This works
$this->assertTrue( !is_null($person->foo) );
if ( $person->foo ) {
$this->assertTrue( $person->foo->is($user) );
}
// This fails
$this->assertTrue( !is_null($person->user) );
if ( $person->user ) {
$this->assertTrue( $person->user->is($user) );
}
By request, here is all of the code relating to Person,

I have to be honest - quickly looking at the code I don't see anything wrong but it doesn't mean everything is for sure ok.
If I were you, I would try to limit Person model just to:
class Person extends \Illuminate\Database\Eloquent\Model {
protected $fillable = [
'person_type_id',
'email',
'fname',
'lname',
'user_id',
'modified_by_user_id',
'audited_at',
'custom_attributes'
];
protected $casts = [
'custom_attributes' => 'json',
'user_id' => 'integer',
'modified_by_user_id' => 'integer',
'person_type_id' => 'integer'
];
protected $dates = [
'audited_at'
];
public static $transformer = PersonTransformer::class;
public function user() {
return $this->belongsTo(User::class, 'user_id', 'id');
}
public function type() {
return $this->belongsTo(PersonType::class, 'person_type_id');
}
public function assets() {
return $this->hasMany(Asset::class, 'person_id');
}
}
and now I would verify if everything is fine. If it's fine, now you could investigate this further, add one trait and verify, add second trait and verify, finally extend from same class.
There must be bug somewhere but looking at this code it's hard do find anything
user is reserved name in eloquent.
try User instead of user
public function User() {
return $this->belongsTo(User::class, 'user_id', 'id');
}
