Calling model inside a middleware laravel - php

I am trying to call a model Readdb inside a middleware. but I am getting error :
Class 'app\Models\Readdb' not found
My middlware code is:
<?php
namespace App\Http\Middleware;
use Closure;
use App\Models\Readdb;
class Adminlogin {
public function handle($request, Closure $next) {
if (!$request->session()->has('userid')) {
$db = new Readdb();
return response()->view('admin.auth.login');
} else {
return response()->view('admin.dash');
}
return $next($request);
}
}
Readdb File:
<?php
namespace App;
use \Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\DB;
class Readdb extends Model {
public function get_setting($name) {
$data = DB::table('setting')->select('value')->where('name', '=', $name)->get();
return $data->value;
}
}
path to readdb is: /var/www/html/ecommerce/app/Models/Readdb.php

Your Readdb exists in the namespace App, not App\Models, so either do this in the middleware:
use App\Readdb;
Or, if your composer.json says to look for App\Models in the app/Models dir, update the namespace on Readdb:
namespace App\Models;

inheritance i laravel :Class name must be a valid object or a string

this is my parent class which is a user class that has the main crud operations
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Repositories\UserRepository; //<----------- Here
class UserController extends Controller
{
protected $model;
public function index()
{
$users = $this->model::all();
return view('users.index', compact('users'));
}
}
this is my child class which is one of my user roles , it have the same crud operation but it need some more functinality
<?php
namespace App\Http\Controllers;
use App\Models\Teacher;
use App\Http\Controllers\UserController;
class TeacherController extends UserController
{
public function __construct()
{
$this->model = Teacher::class;
}
}
when I try to access the route i get this error : Class name must be a valid object or a string
at :
$users = $this->model::all();
Well, it seems my Laravel project used old cached routes. Just run
php artisan route:clear
from time to time before debugging anything.

undefined type Auth

namespace App\Http\Controllers;
use Auth;
use Illuminate\Http\Request;
class maincontroller extends Controller
{
public function home(Request $request)
{
if(Auth::Attempt($request->only('email','password'))) {
return redirect('/');
}
}
}
Change the Auth namespace to:
use Illuminate\Support\Facades\Auth;
You may use the auth helper instead and then no worries about any class name
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class maincontroller extends Controller
{
public function home(Request $request)
{
if(auth()->attempt($request->only('email','password'))) {
return redirect('/');
}
}
}
Try this :
\Auth::attempt([...]);
I think this is helpfull..
Use the Auth namespace to:
use Illuminate\Support\Facades\Auth;

Can't use laravel singleton inside Middleware

I have a custom middleware where I want to use a singleton I use to pass php variables into my frontend, however I get the following error:
ReflectionException (-1)
Class App\Http\Middleware\Javascript does not exist
My middleware:
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Http\Request;
use Auth;
class AuthAdmin
{
public function handle($request, Closure $next)
{
$user = Auth::user();
if($user && $user['privileges'] > 2)
{
return $next($request);
}
app(Javascript::class)->put(['showLoginModal' => true]);
return redirect('/');
}
}
My ServiceProvider:
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\Helpers\Javascript;
class JavascriptServiceProvider extends ServiceProvider
{
public function register()
{
$this->app->singleton(Javascript::class, Javascript::class);
}
}
composer dump-autoload didn't fix anything, I have been having problems where the Javascript Class is not found for some reason, any ideas or sugestions?
Try importing Javascript class in your middleware. It's trying to find it in wrong namespace.
middleware:
<?php
namespace App\Http\Middleware;
use App\Helpers\Javascript;

Class App\Http\Controllers\Panel does not exist

I'm following the Laracasts series and have run into an issue on the episode Laravel 5.4 From Scratch: Route Model Binding.
Laravel version:
Laravel Framework 5.6.13
The error:
Class App\Http\Controllers\Panel does not exist
This shows on both the /panel and /panel/1 pages
App\Http\Controllers\PanelController.php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
// Code works if I uncomment below line, and change the show function to "show($panel)"
//use App;
class PanelController extends Controller
{
public function index()
{
$panels = Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}
routes/web.php
// Main panel view
Route::get('/panel', 'PanelController#index');
// Individual panel view
Route::get('/panel/{panel}', 'PanelController#show');
App/Panel.php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Panel extends Model
{
public static function activePanels()
{
return static::where('status', 1)->get();
}
}
Add this line in panel controller before the class
use App\Panel;
You need to add use App\Panel; to top of class
Or call it by full namespace $panels = App\Panel::all();
You don't included your model to class.
Add App\Panel to main include section:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Panel;
class PanelController extends Controller
{
public function index()
{
$panels = Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}
or load model in your class method manually:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class PanelController extends Controller
{
public function index()
{
$panels = App\Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}

Laravel 5 - Where to define functions and call them in views & controllers

I have following function and want to call it from view. Basically i want to put all common functions in one file. I am not sure where to create that file and how to call it inside controller and view.
<?php namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
public function BytesToMB($bytes=0)
{
if(empty($bytes))
return 0;
$kb = ceil($bytes/1024);
$mb = ceil($kb/1024);
return $mb;
}
}
So far i have created CommonController.php in app/Http/Controllers and put above function in it.
Then in other controller i have tried to call it following way:
use App\Http\Controllers\Common;
class SongsController extends Controller {
public function index($id)
{
echo Common::BytesToMB('7012187');
}
}
But i am getting error:
Class 'App\Http\Controllers\Common' not found
Ok, new try. You missed to use the complete class name and add the static keyword:
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
public static function BytesToMB($bytes=0)
{
if(empty($bytes))
return 0;
$kb = ceil($bytes/1024);
$mb = ceil($kb/1024);
return $mb;
}
}
And then:
<?php
namespace App\Http\Controllers;
// You do not need to define this, if you are in the same namespace
use App\Http\Controllers\CommonController;
class SongsController extends Controller {
public function index($id)
{
echo CommonController::BytesToMB('7012187');
}
}
Another and more OOP solution is to use the function from the parent class:
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use DB;
class CommonController extends Controller {
protected function BytesToMB($bytes=0)
{
if(empty($bytes))
return 0;
$kb = ceil($bytes/1024);
$mb = ceil($kb/1024);
return $mb;
}
}
And then:
<?php
namespace App\Http\Controllers;
// You do not need to define this, if you are in the same namespace
use App\Http\Controllers\CommonController;
class SongsController extends CommonController {
public function index($id)
{
echo $this->bytesToMB('7012187');
}
}
