as I mentioned in last question I am beginner in Laravel therefore I need some help ,I have to make helper class to create random Id for some tables ,I create this class with table constructor to recieve deffirent tables :
<?php
namespace App\Helpers;
use Illuminate\Support\Facades\DB;
class RandomId
{
public function __construct($my_table)
{
$this->my_table=$my_table;
}
public function get_id()
{
$id = mt_rand(1000000000, 9999999999);
if($this->check_id($id)){
get_id();
}
return $id;
}
public function check_id($id)
{
$table=DB::table($this->my_table)->where('id',$id)->get();
if (count($course)==0){
return false;
}
return true;
}
}
then I add it as alias in config/app.php
'RandomId' => App\Helpers\RandomId::class,
now I want to call it in controller ,I did somethinf like this but don't work :
<?php
namespace App\Http\Controllers\course;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Helpers\RandomId;
class Course_controller extends Controller
{
public function add(Request $request)
{
$id=RandomId::get_id('courses');
dd($id);
}
}
I get this error :Non-static method App\Helpers\RandomId::get_id() should not be called statically
It's because get_id function is not static. You should add static keyword when defining static methods:
public static function get_id()
{
....

This is the code of model. I am unable to change access the function of conversation using the model method as i am passing data from view to botman conversation constructor through request.
<?php
This is the conversation class
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use App\Conversations\TestConversation;
class CheckSaved extends Model
{
public function hasDate($scheduled_date):bool
{
if($scheduled_date)
{
$testconv = new TestConversation($scheduled_date);
$testconv->showOther();
}
return false;
}
}][1]
<?php
namespace App\Conversations;
use BotMan\BotMan\Messages\Incoming\Answer;
use BotMan\BotMan\Messages\Conversations\Conversation;
use App\Http\Traits\PropertyDetails;
use App\Models\CheckSaved;
class TestConversation extends Conversation
{
public $is_saved;
public function __construct($request)
{
if(isset($request->scheduled_date))
{
$checkDate = new CheckSaved();
$this->is_saved = $checkDate->hasDate($request->scheduled_date);
}
}
public function sayHi()
{
// dd($request);
$this->say("<input type='datetime-local' id='birthdaytime' name='birthdaytime'>");
$this->say("<button class='btn-date' onclick='test()'>Save</button>");
}
public function showOther()
{
$this->say('Hi');
}
public function run()
{
$this->sayHi();
}
}
This is the image of Model
I am getting reply() on null if try to call a function called "showOther()" inside TestConversation. I am stuck on it please someone help or contact me.
In laravel 6 app I created facade app/Facades/MyFuncsClass.php :
<?php
namespace App\Facades;
use Illuminate\Support\Facades\Facade;
class MyFuncsClass extends Facade{
protected static function getFacadeAccessor() { return 'MyFuncsClass'; }
}
But I got error :
"message": "Non-static method App\\Helpers\\MyFuncsClass::debToFile() should not be called
statically",
calling it from boot method:
protected static function boot() {
parent::boot();
static::deleting(function($task) {
$hostel_image_image_path= Task::getTaskImagePath($task->id, $task->image);
MyFuncsClass::debToFile(print_r($hostel_image_image_path, true), '-9 $hostel_image_image_path::');
...
Is there is a way to escape this error and run MyFuncsClass::debToFile in boot method ?
MODIFIED :
Sure I registered my facade in config/app.php, 'providers' block :
...
App\Providers\MyFuncsClassProvider::class,
file app/Http/Helpers/MyFuncsClass.php has a lot of public methods, with heading:
<?php
namespace App\Helpers;
use Illuminate\Http\Request;
use Barryvdh\Debugbar\Facade as Debugbar;
use Carbon\Carbon;
use Illuminate\Support\Facades\File;
use Illuminate\Support\Facades\Storage;
class MyFuncsClass {
public $concat_str_max_length = 50;
public $m_concat_str_add_chars = '...';
public function debToFile($contents, string $descr_text = '', bool $is_sql = false, string $file_name = '')
{
try {
...
and in app/Providers/MyFuncsClassProvider.php :
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\App;
class MyFuncsClassProvider extends ServiceProvider
{
/**
* Register services.
*
* #return void
*/
public function register()
{
App::bind('MyFuncsClass', function()
{
return new \App\Helpers\MyFuncsClass;
});
}
/**
* Bootstrap services.
*
* #return void
*/
public function boot()
{
//
}
}
Actually I can call \MyFuncsClass::debToFile( ok from not static methods, like control actions, but I have the error
calling from static boot method...
MODIFIED # 2 :
With real time facades https://laravel.com/docs/5.7/facades#real-time-facades defintions
I tried
<?php
namespace App;
use DB;
use Illuminate\Support\Facades\File;
use Illuminate\Support\Facades\Storage;
use App\Facades\MyFuncsClass;
use App\Http\Helpers\MyFuncsClassContainer; // Alias for my helper class
use Illuminate\Database\Eloquent\Model;
use Barryvdh\Debugbar\Facade as Debugbar;
class Task extends Model
{
use Sluggable;
protected $table = 'tasks';
protected $primaryKey = 'id';
}
protected static function boot() {
parent::boot();
static::deleting(function($task) {
$hostel_image_image_path= Task::getTaskImagePath($task->id, $task->image);
\Log::info( '-9 $hostel_image_image_path::' );
\Log::info( print_r($hostel_image_image_path, true) );
$myFuncsClassCore = factory(MyFuncsClassContainer::class)->create();
$myFuncsClassCore->debToFile(' debToFile string REDSA');
Bur anywat I got error :
Cannot declare class App\Helpers\MyFuncsClassContainer, because the name is already in use {"userId":1,"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalErrorException
I tried a way to rename my helper class to “MyFuncsClassContainer”, supposing
having the same name for helper and facade could raise error, but failed
If there is a way to fix this error ?
Thanks!
I can not insert data in my table with migration
I have tried to put everywhere app/address, but this did not help me.
Can someone help me?
I want to know what is wrong here.
<?php
namespace App\Http\Controllers;
use App\Address;
use App\User;
use Illuminate\Http\Request;
class AddressController extends Controller
{
public function index()
{
//
}
public function create()
{
$user = User::findOrFail(1);
$address = new Address(['name' => 'ginta latina 11']);
$user->address()->save($address);
}
}
Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR)
Class 'App/Address' not found
Here is the model:
<?php namespace App;
use Illuminate\Database\Eloquent\Model;
class Address extends Model
{
protected $fillable = ['name'];
}
and here is where I am using the class:
public function address()
{
return $this->hasOne('App/Address');
}
Your hasOne('App/Address') should be hasOne('App\Address') notice the \ not the /.
This would mean your function would look like:
public function address()
{
return $this->hasOne('App\Address');
}
Alternatively, I would recommend using ::class instead:
public function address()
{
return $this->hasOne(Address::class);
}
If the Address class is not in the same namespace as the class you're using it in then you will need to add use App\Address; as well.
In Laravel 8.x,
use App\Address;
is replaced with
use App\Models\Address;
I am using laravel 5.6, when create controller and when run controller through route, I am facing error like
Declaration of App\Http\Controllers\XyzController::xyz(Illuminate\Http\Request $request) should be compatible with App\Http\Controllers\Controller::xyz($job)
My Code is
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class XyzController extends Controller
{
public function xyz(Request $request)
{
return view('xyz.xyz');
}
}
Missing route parameter: $job
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class XyzController extends Controller
{
public function xyz(Request $request, $job)
{
return view('xyz.xyz');
}
}
The base Controller that XyzController extends from defines a method named xyz with a different signature than the one you are defining.
You will need to adjust the method in XyzController to match the signature of xyz in the base Controller or adjust the base Controller to have a different signature.
Example of the problem:
class A
{
public function xyz($obj) {}
}
class B extends A
{
public function xyz(Illuminate\Http\Request $request) {}
}
Declaration of B::xyz(Illuminate/Http/Request $request) should be compatible with A::xyz($obj)
You forgot to use controller?
use App\Http\Controllers\Controller as Controller
I've just crossed this example, but it fails to resolve binding interface to implementation.
Having the follow code files:
// File: app/App/Services/Talkable.php
<?php
namespace App\Services;
interface Talkable {
public function talk();
}
// File: app/App/Services/Cat.php
<?php
namespace App\Services;
use App\Services\Talkable;
class Cat implements Talkable
{
public function talk()
{
return 'meow meow';
}
}
// File: app/Jobs/MakeSomeNoise.php
<?php
namespace App\Jobs;
use App\Jobs\Job;
use App\Services\Talkable;
class MakeSomeNoise extends Job
{
private $talkable;
public function __construct(Talkable $talkable)
{
$this->talkable = $talkable;
}
public function handle()
{
return ($this->talkable->talk());
}
}
The binding are taken place in app/Providers/AppServiceProvider.php
// File: app/Providers/AppServiceProvider.php
...
$this->app->bind('App\\Services\\Talkable', 'App\\Services\\Cat');
The MakeSomeNoise job is dispatched from a Controller
// File: any controller
public function makeNoises()
{
return $this->dispatch(new MakeSomeNoise); // (*)
}
At the (*), I expect Laravel will automatically resolve the binding, but it doesn't. Here the error,
Argument 1 passed to App\Jobs\MakeSomeNoise::__construct() must be an instance of App\Services\Talkable, none given, called in ...
But if I just inject into controller constructor, it works fine.
Any thought on this?
My mistake in the code. The DI should be taken in handle() method, not constructor.
public function handle(Talkable $talkable) {
// blah lbah
}
