I have problem when i try to use routes. It can't be generated, i tried via /app/config/routes.xml but when i modify i get error that the file is not YAML format.
The controller looks:
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Request;
class MainController extends Controller
{
public function indexAction(Request $request)
{
return $this->render('main/index.html.twig', [
'base_dir' => realpath($this->getParameter('kernel.project_dir')).DIRECTORY_SEPARATOR,
]);
}
}
When i try to visit /index or main/index it gives me route not found!
:#
Nor works when i put use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; first before Controller.
First, you have to put namespace on header.
Second in Symfony 3.3.10 which route you want to use have to declare before on public function indexAction.
So, your route declaration would be as follows:
namespace AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Request;
class MainController extends Controller
{
/**
*#Route("visit/index")
*/
public function indexAction(Request $request)
{
return $this->render('main/index.html.twig', ['base_dir' => realpath($this->getParameter('kernel.project_dir')).DIRECTORY_SEPARATOR,]);
}
}

My route in api.php is like below
Route::apiResource('/suras', 'SuraController');
My Model Sura.php is like below
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Sura extends Model
{
}
My Controller SuraController.php is like below
<?php
namespace App\Http\Controllers;
use App\Model\Sura;
use Illuminate\Http\Request;
class SuraController extends Controller
{
public function index()
{
return Sura::all();
}
}
I am trying to browse in below URL
http://127.0.0.1:8000/api/suras
I am getting below error
It's looking for the class:
App\Model\Sura
But you declare your namespace as:
namespace App; // Which gives App\Sura
Therefore, just change the namespace of your class to:
namespace App\Model;
And move the class into app/Model directory.
I am new in using policies in Laravel. I am learning API Development using Laravel. My codes are as bellows.
TopicPolicy.php
<?php
namespace App\Policies;
use App\User;
use App\Topic;
use Illuminate\Auth\Access\HandlesAuthorization;
class Topicpolicy
{
use HandlesAuthorization;
public function update(User $user, Topic $topic)
{
return $user->ownsTopic($topic);
}
public function destroy(User $user, Topic $topic)
{
return $user->ownsTopic($topic);
}
}
AuthServiceProvider.php
<?php
namespace App\Providers;
use Laravel\Passport\Passport;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
class AuthServiceProvider extends ServiceProvider
{
protected $policies = [
'App\Model' => 'App\Policies\ModelPolicy',
];
public function boot()
{
$this->registerPolicies();
Passport::routes();
}
}
TopicController.php
<?php
namespace App\Http\Controllers;
use App\Topic;
use App\Post;
use Illuminate\Http\Request;
use App\Http\Requests\StoreTopicRequest;
use App\Transformers\TopicTransformer;
use League\Fractal\Pagination\IlluminatePaginatorAdapter;
class TopicController extends Controller
{
public function destroy(Topic $topic) {
$this->authorize('destroy',$topic);
$topic->delete();
return response(null,204);
}
}
I am getting error This action is unauthorized.. I don't know how to use policies. Could anyone guide me to use policies in Laravel 5.5.14 ?
In the AuthServiceProvider class you have to register the policy in the policies aray. Laravel documents is a good place to start
protected $policies = [
\App\Topic::class => \App\Policies\Topicpolicy::class
]
Second obtain a personal token from your app so you can use it to make calls to your api. You use passport and passport comes with ready to use Vue components to help you start.If you want to consume the api inside the same application check here.
I am not sure what you try to accomplice with the HandlesAuthorization trait inside the policy. Laravel has a middleware for this reason for us to use.
I'm newbie in Yii, especially Yii2. How can I create MY_Controller like CI in YII2 ? so other controllers will extend to MY_Controller.
in YII2, called as BaseController. I think in another framework have same name BaseController .
First, if you're using basic template, create BaseController.php inside component directory.
namespace app\components;
use Yii;
use yii\web\Controller;
use yii\helpers\Url;
class BaseController extends Controller
{
public function init()
{
parent::init();
}
public function _anotherMethod(){ /* your code goes here */ }
}
Next in your other controllers :
namespace app\controllers;
use Yii;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
use yii\helpers\Url;
use app\components\BaseController;
class YourController extends BaseController
{
public function init()
{
parent::init();
}
public function _anotherAction()
{
// your code
}
}
I hope it will help you
I can get the ID of the authenticated user like this:
Auth::user()->id = $id;
Great it works, ... but I have a load of methods which need it and I want a cleaner way of adding it to the class as a whole,so I can just reference the $id in each method. I was thinking of putting it into the constructor, but as Auth::user is a static, I am making a mess of things and don't know how to do it.
Many thanks for your help !
Laravel >= 5.3
you can't access the session or authenticated user in your controller's constructor because the middleware has not run yet.
As an alternative, you may define a Closure based middleware directly in your controller's constructor. Before using this feature, make sure that your application is running Laravel 5.3.4 or above:
class UserController extends Controller {
protected $userId;
public function __construct() {
$this->middleware(function (Request $request, $next) {
if (!\Auth::check()) {
return redirect('/login');
}
$this->userId = \Auth::id(); // you can access user id here
return $next($request);
});
}
}
Instead of using the Facade you can inject the contract for the authentication class and then set the user ID on your controller. Like #rotvulpix showed you could put this on your base controller so that all child controllers have access to the user ID too.
<?php
namespace App\Http\Controllers;
use Illuminate\Contracts\Auth\Guard;
class FooController extends Controller
{
/**
* The authenticated user ID.
*
* #var int
*/
protected $userId;
/**
* Construct the controller.
*
* #param \Illuminate\Contracts\Auth\Guard $auth
* #return void
*/
public function __construct(Guard $auth)
{
$this->userId = $auth->id();
}
}
The guard has an id() method which returns void if no user is logged in, which is a little easier than having to go through user()->id.
You can use Auth::user() in the whole application. It doesn't matter where you are. But, in response to your question, you can use the 'Controller' class present in your controllers folder. Add a constructor there and make the reference to the user ID.
<?php namespace App\Http\Controllers;
use Illuminate\Foundation\Bus\DispatchesCommands;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
/* Don't forget to add the reference to Auth */
use Auth;
abstract class Controller extends BaseController {
use DispatchesCommands, ValidatesRequests;
function __construct() {
$this->userID = Auth::user()?Auth::user()->id:null;
}
}
Then, in any method of any controller you can use the $this->userID variable.
I am new to yii.
I am using more than 1 controller in my website and each controller has few actions.
I want to use some variables across each controller (Value of variable will be fixed, I need some constants for a formula). Whats the best place (standard way) to define those variables ?
Should I use session ? (as value is not going to change).
Not sure what you are using your vars for, but you can do it by defining them in your config main.php
'params'=>array(
'someVar1'=>'varValue1',
'someVar2' => 'varValue2',
),
Then you can access them in ANYWHERE by calling
Yii::app()->params['someVar1']
They will be available anywhere in your application.
Or you can extend all your controllers off of a base class and define your constants there
Base Controller:
class Controller extends CController {
const SOME_VAR = 'someValue';
}
Your controller:
class YourController1 extends Controller
{
public function actionIndex()
{
echo parent::SOME_VAR;
}
}
Your other controller:
class YourController2 extends Controller
{
public function actionLogin()
{
echo parent::SOME_VAR;
}
}
