I am creating a command and a helper function in laravel.
In app/Helper/Function.php
<?php
namespace App\Helper;
class Function
{
static public function testCommand()
{
return "success";
}
}
In Console/Commands/TestCommand.php
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
class TestCommand extends Command
{
protected $signature = 'test:command';
protected $description = 'Test Command';
public function __construct()
{
parent::__construct();
}
public function handle()
{
// call the helper's testCommand function here
}
}
Now I want to call the testCommand() function on function handle() to process
And when I run: : php artisan test:command then it will get the result of the function :testCommand() . Thanks
I found the solution:
<?php
namespace App\Console\Commands;
use App\Helper\Function;
use Illuminate\Console\Command;
class TestCommand extends Command
{
protected $signature = 'test:command';
protected $description = 'Test Command';
public function __construct()
{
parent::__construct();
}
public function handle()
{
$test = Function:: testCommand();
return $test;
}
}

I tried to register my ObserverHelper in the AppServiceProvider as below, but I am getting the following error.
Unable to find observer: App\Helpers\App\Observers\FileLogObserver
AppServiceProvider.php
use Illuminate\Support\ServiceProvider;
use App\Helpers\ObserverHelper;
class AppServiceProvider extends ServiceProvider
{
public function register()
{
}
public function boot()
{
ObserverHelper::register();
}
}
ObserverHelper.php
namespace App\Helpers;
class ObserverHelper
{
protected static $observers = [
'App\Models\FileLogs' => App\Observers\FileLogObserver::class,
];
public static function register()
{
foreach (self::$observers as $model => $observer) {
$model::observe($observer);
}
}
}
Try adding a \ (backslash that references the global namespace) in front of the App\Observers\FileLogObserver::class, or import that class.
With backslash (reference global namespace):
<?php
namespace App\Helpers;
class ObserverHelper
{
protected static $observers = [
'App\Models\FileLogs' => \App\Observers\FileLogObserver::class,
];
public static function register()
{
foreach(self::$observers as $model => $observer) {
$model::observe($observer);
}
}
}
or with import:
<?php
namespace App\Helpers;
use App\Observers\FileLogObserver;
class ObserverHelper
{
protected static $observers = [
'App\Models\FileLogs' => FileLogObserver::class,
];
public static function register()
{
foreach(self::$observers as $model => $observer) {
$model::observe($observer);
}
}
}
Note: Even though your code is a valid solution, consider creating a separate provider for defining observers (ObserverServiceProvider for example).
Hello I want to use my own repository class in my Laravel 5.8 project
I created my file Repository in the App File and in this file I added A class called ConversationRepository
This is my class:
<?php
namespace App\Repository;
class ConversationRepository{
private $user;
public function __construct(User $user){
$this->user=$user;
}
public function getConversation(int $userId){
return $this->user->newQuery()
->select('name','id')
->where('id','!=',$userId)
->get();
}
}
And then when I use it on my controller :
<?php
namespace App\Http\Controllers;
use App\User;
use Auth;
use Illuminate\Http\Request;
use App\Repository\ConversationRepository;
class ConversationsController extends Controller
{
private $r;
private $auth;
public function __construct(ConversationRepository $conversationRepository,AuthManager $auth){
$this->r = $conversationRepository;
$this->auth = $auth;
}
public function index(){
return view('conversation.index',[
'users'=>$this->r->getConversation($this->auth->user()->id)
]);
}
public function show(User $user){
return view('conversation.show',['users'=>$this->r->getConversation(
$this->auth->user()->id),
'user'=>$user
]);
}
public function store(User $user){
}
}
I get the error
Class App\Repository\User does not exist
Apparently, you forgot to add use App\User; in the class ConversationsController file.
I can't get my repository working, when i'm just trying the get the entire list of documents it returns nothing
Here's my DocumentRepository
<?php
namespace App\Repositories\Document;
interface DocumentRepository
{
public function getall();
public function getById($id);
public function create(array $attributes);
public function update ($id, array $attributes);
public function delete ($id);
}
Here's the functions
<?php
namespace App\Repositories\Document;
class EloquentDocument implements DocumentRepository
{
private $model;
public function __construct(Document $model)
{
$this->model = $model;
}
public function getall()
{
return $this->model->all();
}
public function getById($id)
{
return $this->findById($id);
}
public function create(array $attributes)
{
return $this->model->create($attributes);
}
public function delete($id)
{
$this->getById($id)->delete();
return true;
}
public function update($id array $attributes)
{
$document = $this->model->findOrFail($id);
$document->update($attribute);
return $document;
}
}
and here's the controller
<?php
namespace App\Http\Controllers;
use App\Repositories\Document;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class DocumentController extends Controller
{
/**
* #var DocumentRepository
*/
private $document;
/**
* TodoController constructor.
*/
public function __construct(DocumentController $document)
{
$this->document = $document;
}
public function getalldocuments()
{
return $this->document->getAll();
}
}
For your information there's two rows of data in my Documents table/model so i just want to get both of them by just simply returning but in my case it simply returns nothing.
Here's the route
Route::get('/documents', 'DocumentController#getalldocuments');
here's the registration part insite AppServiceProviders.php
public function register()
{
$this->app->singleton(DocumentRepository::class, EloquentDocument::class);
}
You are type-hinting DocumentController instead of your actual repository.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Repositories\Document\DocumentRepository;
class DocumentController extends Controller
{
/**
* #var DocumentRepository
*/
private $document;
public function __construct(DocumentRepository $document)
{
$this->document = $document;
}
public function getalldocuments()
{
return $this->document->getAll();
}
}
Now, assuming you have properly binded the interface to resolve to your document repository implemented, this should work.
For more information on how to bind interfaces to implementation, read this: https://laravel.com/docs/5.7/container#binding-interfaces-to-implementations
Edit: You have some syntax issues in your repository's interface. You are missing function:
<?php
namespace App\Repositories\Document;
interface DocumentRepository
{
public function getall();
public function getById($id);
public function create(array $attributes);
public function update($id, array $attributes);
public function delete($id);
}
Edit 2: Your binding is correct. However, I noticed that you are not binding your App\Document model to the implementation correctly.
<?php
namespace App\Repositories\Document;
use App\Document;
class EloquentDocument implements DocumentRepository
{
private $model;
public function __construct(Document $model)
{
$this->model = $model;
}
//
//
//
}
You need to add the correct use statement at the top. Assuming your document model resides in App\Document this should work.
I want to have one public variable $users = User::all(); so i could use it in different methods inside controller and it doesn't work this way:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\User;
class AdminController extends Controller
{
public $users = User::all();
public function __construct() {
$this->middleware('auth');
}
public function index()
{
return view('admin.index');
}
public function showUsers()
{
return view('admin.users', compact('users'));
}
}
i get this error: Constant expression contains invalid operations
What am i doing wrong?
Try adding the assignment into the __construct() function instead:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\User;
class AdminController extends Controller
{
public $users;
public function __construct() {
$this->users = User::all();
$this->middleware('auth');
}
public function index()
{
return view('admin.index');
}
public function showUsers()
{
$users = $this->users;
return view('admin.users', compact('users'));
}
}
You need to initialize $users in your constructor:
<?php
public $users;
public function __construct() {
$this->middleware('auth');
$this->users = User::all();
}
I'm using Lumen and want to know how to pass data to my job class.
I have my job class like below;
<?php
namespace App\Jobs;
use App;
use Illuminate\Contracts\Mail\Mailer;
class TestEmailJob extends Job
{
/**
* Create a new job instance.
*
* #return void
*/
public function __construct()
{
//
}
/**
* Execute the job.
*
* #return void
*/
public function handle(Mailer $mailer)
{
//
$data; // I want to pass this from my function
$mailer->queue('emails.emailtemplate', $data , function ($message) {
$message->from('support#xxx.com', 'Laravel');
$message->to('xxx#gmail.com')->cc('xxx#yahoo.co.uk');
});
}
}
I then have a function to push the job on the queue;
public function emailTest () {
$data = ['user' => $user];
Queue::push(new TestEmailJob);
}
How can I pass $data and receive it and use it in the job class?
You can instantiate the variable by passing to the constructor
class TestEmailJob extends Job implements SelfHandling, ShouldQueue
{
use InteractsWithQueue;
protected $data;
public function __construct($data)
{
$this->data = $data;
}
public function handle()
{
// $this->data;
}
}
Now from the Controller, you can call it like:
$this->dispatch(new TestEmailJob($data));
