I know that this question was asked so many times, but none of answers helped me.
I'm getting exception in Laravel 5
BindingResolutionException in Container.php line 785:
Target [App\Contracts\CustomModelInterface] is not instantiable.
What I've done without success:
Register App\Providers\AppRepositoryProvider in app.php providers
php artisan clear-compiled
Everything works if I replace interfaces on repositories in MyService, but I feel that it's wrong (should it be handled by IoC container?).
Structure:
app
- Contracts
- CustomModelInterface.php
- Models
- CustomModel.php
- Repositories
- CustomModelRepository.php
- Providers
- AppRepositoryProvider.php
- Services
- MyService.php
App\Contracts\CustomModelInterface.php
<?php namespace App\Contracts;
interface CustomModelInterface {
public function get();
}
App\Repositories\CustomModelRepository.php
<?php namespace App\Repositories;
use App\Contracts\CustomModelInterface;
use App\Models\CustomModel;
class CustomModelRepository implements CustomModelInterface {
private $Model;
public function __construct(CustomModel $model) {
$this->Model = $model;
}
public function get() {
return 'result';
}
}
App\Services\MyService.php (Keep business logic / layer between controller and repositories)
<?php namespace App\Services;
use App\Contracts\CustomModelInterface;
class MyService {
private $Model;
public function __construct(CustomModelInterface $customModel) {
$this->Model= $customModel;
}
public function getAll() {
return $this->Model->get();
}
}
App\Providers\AppRepositoryProvider.php
<?php namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class AppRepositoryProvider extends ServiceProvider {
public function boot() {}
public function register() {
$models = array(
'CustomModel'
);
foreach ($models as $idx => $model) {
$this->app->bind("App\Contracts\{$model}Interface", "App\Repositories\{$model}Repository");
}
}
}
My controller looks like:
<?php namespace App\Http\Controllers;
use App\Services\MyService;
class SuperController extends Controller {
private $My;
public function __construct(MyService $myService) {
$this->My = $myService;
}
public function getDetails() {
return $this->My->getAll();
}
}
composer.json
"autoload": {
"classmap": [
"database"
],
"psr-4": {
"App\\": "app/",
"App\\Models\\": "app/Models/",
"App\\Contracts\\": "app/Contracts/",
"App\\Repositories\\": "app/Repositories/"
}
},
Thank you everyone, but problem was in my AppRepositoryProvider. As it's binding exception, then obviously the problem was with binding :)
Correct file is:
<?php namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class AppRepositoryProvider extends ServiceProvider {
public function boot() {}
public function register() {
$models = array(
'CustomModel',
'CustomModel2',
'CustomModel3'
);
foreach ($models as $model) {
$this->app->bind("App\Contracts\\{$model}Interface", "App\Repositories\\{$model}Repository");
}
}
}
Note, that I'm using "App\Contracts\\{$model}Interface" (not escaping "{" symbol) and it generate correct string App\Contracts\CustomModelInterface instead of App\Contracts\{$model}Interface (with unexpected escaping).
Every time I create a new repository/contract pair I make sure I do the following:
check the classes used in the service provider (copy/paste the namespaces)
register a new binding in config/app.php
php artisan optimize
Many hours of useless debugging led me to this short checklist.
For me, I forgot to bind in app->providers->RepositoryServiceProvider
the repository like this in the register method
public function register()
{
$this->app->bind(
\App\Play\Contracts\PatientRepository::class,
\App\Play\Modules\PatientModule::class
);
}
Make sure your RepositoryServiceProvider is registered in AppServiceProvider.
public function register()
{
$this->app->register(RepositoryServiceProvider::class);
}
I got past this error running:
php artisan config:clear
php artisan clear-compiled
php artisan optimize
php artisan config:cache
Related to:
Target is not instantiable. Laravel 5 - App binding service provider
The problem is solved by adding your repository in app/providers/AppServiceProvider
like the example below.
public function register()
{
$this->app->singleton(UserRepository::class, EloquentUser::class);
}
Dont forget the name space
use Test\Repositories\EloquentUser;
use Test\Repositories\UserRepository;
It worked for me
On App\Services\MyService.php you are passing that interface with dependency injection which tries to instantiate that -
public function __construct(CustomModelInterface $customModel) {
$this->Model= $customModel;
}
which is wrong.
Try implement that in that class - class MyService implements CustomModelInterface { and use the function of that interface like -
$this->get();
Or you are using it - class CustomModelRepository implements CustomModelInterface {
So if you do -
public function __construct(CustomModelRepository $customModel) {
$this->Model= $customModel;
}
then also you can access the interface methods.
I've just experienced an issue similar to this and the cause of my error was that I had set $defer to true in the service provider class but I had not implemented the required provides() method.
If you have deferred the creation of your class until it is need rather than it being loaded eagerly, then you need to also implement the provides method which should simply return an array of the classes that the provider provides. In the case of an interface, I believe it should be the name of the interface rather than the concrete class.
E.g.
public method provides(): array
{
return [
MyInterface::class,
];
}
Current documentation: https://laravel.com/docs/5.5/providers#deferred-providers
I hope this helps somebody else.
Don't worry guys. I have a solution to your problem.
I have an example for you.
Step1: php artisan make:repository Repository/Post //By adding this command you can create a repository and eloquent files
Step2: After adding that file you have to add/use this repository in the controller in which you want to use.
for eg: use App\Repositories\Contracts\PostRepository;
Step3: After adding that repo in your controller if you will run the app you will get an error like " Interface is not instantiable". It comes because you have created a repo and used in a controller, but laravel don't know where this repository is register and bind with which eloquent. So that it throws an error.
Step4: To solve this error you have to bind your repo with your eloquent in AppServiceProvider.
E.g:
AppServiceProvider.php file
<?php
namespace App\Providers;
// **Make sure that your repo file path and eloquent path must be correct.**
use App\Repositories\Contracts\PostRepository; // **Use your repository here**
use App\Repositories\Eloquent\EloquentPostRepository; **// Use your eloquent here**
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider {
/**
* Register any application services.
*
* #return void
*/
public function register() {
**// And bind your repository and eloquent here. **
$this->app->bind(PostRepository::class, EloquentPostRepository::class);
}
}
Step5: After binding repo and eloquent you can use all method of repo in your controller. Enjoy.....
Please let me know if you have any query.
execute this command :
composer dump-autoload
this command will remap your laravel autoload classes together with all other vendor's i had same issue before and this did the trick you can use it together with "-o" param for optimization .
Note that this can also be caused by the _constructor on the class being declared private, or otherwise being blocked...
If it cant call the constructor, the binding will fail
I think the problem here is that you don't bind App\Contracts\CustomModelInterface to anything so Laravel tries to create instance of interface.
In App\Providers\AppRepositoryProvider.php you have only:
$models = array(
'Model'
);
but you should have in this array CustomModel also, so it should look like this:
$models = array(
'Model',
'CustomModel',
);
The last thing you do is to use the interface you bound to the repository.
Set it up and try running your laravel app to make sure you get no errors.
In my case I had a mismatch between my repository and interface.
interface UserRepositoryInterface{
public function get($userId);
}
class UserRepository implements UserRepositoryInterface{
public function get(int $userId);
}
As you can see the interface get method does not include a type hint but the UserRepository class' get method has a type hint.
You won't get this error if you immediately start to use your Interface Binding.
register a new binding in config/app.php
In my case I forgot use App\Repositories\UserRepository in App\Providers\AppRepositoryProvider.php
intelephense wasn't complaining and the error-message did not give me any clue, but somehow I found out that it's missing and adding this line did the trick
I had this error, and found out that I should restart the queue because it runs in the job:
php artisan queue:restart
I've been comparing my code to this question and many other guides online but with little success. Everything works fine until I try to inject the the interface in my controller. When I do inject it, I get the Target Interface is not instantiable error.
app\models\Interfaces\InterviewInterface.php
<?php namespace app\models\Interfaces;
interface InterviewInterface {
public function fetch($id);
}
app\models\Interview.php
use app\models\Interfaces\InterviewInterface;
class Interview extends Eloquent implements InterviewInterface {
public function fetch($id)
{
return Interview::find($id);
}
}
routes.php
App::bind('app\models\Interfaces\InterviewInterface');
composer.json
"psr-4": {
"Blog\\Articles\\" : "app/lib/Blog/Articles",
"app\\models\\Interfaces\\" : "app/models/Interfaces/InterviewInterface.php"
}
AdminInterviewController.php
use app\models\Interfaces\InterviewInterface as InterviewInterface;
class AdminInterviewController extends BaseController {
public function __construct(InterviewInterface $interview)
{
$this->interview = $interview;
$this->beforeFilter('auth');
}
}
As soon as I add the
use app\models\Interfaces\InterviewInterface as InterviewInterface;
and
__construct(InterviewInterface $interview)
$this->interview = $interview;
lines, it gives me the error. I pull them out, no error.
I have run php composer.phar dump-autoload and php artisan dump-autoload commands multiple times and they succeed.
Any ideas? I really appreciate it.
You need to bind the interface to a class in order to resolve it from the IOC:
In routes.php, assuming it is not namespaced:
App::bind('app\modesl\Interfaces\InterviewInterface', 'Interview');
I'm attempting to create a repository and have it auto injected into some of my controllers. I am using Laravel 4.1 and PHP 5.3.10
I get the error message Class ConsumerRepositoryInterface does not exist
I've setup a service provider like so...
use Illuminate\Support\ServiceProvider;
class ConsumerServiceProvider extends ServiceProvider {
public function register()
{
$this->app->bind('ConsumerRepositoryInterface', function()
{
return new EloquentConsumerRepository(new Consumer);
});
}
}
I'm trying to inject it into my controller like so.
private $consumer;
public function __construct(ConsumerRepositoryInterface $consumer)
{
$this->consumer = $consumer;
}
I've got the service provider registered in the providers array in config\app.php as ConsumerServiceProvider. I've added app/providers and app/repositories where I have the service provider and repository respectively to the autoload classmap section of the composer.json file and have ran composer dump-autoload.
The confusing part is setting up my controller like so works fine...
private $consumer;
public function __construct()
{
$this->consumer = App::make('ConsumerRepositoryInterface');
}
This tells me the service provider and repositories are all fine, Laravel is for some reason not able to automatically inject my dependency into the controller.
The answer was painfully obvious.
It was saying ConsumerRepositoryInterface did not exist because it didn't exist. As soon as I made an actual interface and setup the EloquentConsumerRepository to implement it, everything worked.
I'm trying to use the extension php_pthreads with Symfony2.
I set up a simple controller:
<?php
namespace Test\TestBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class SimpleThread extends \Thread {
public function run() {
sleep(100);
}
}
class DefaultController extends Controller
{
public function indexAction()
{
$simpleThread = new SimpleThread();
$simpleThread->start();
return $this->render('TestTestBundle:Default:index.html.twig', array('name' => "World"));
}
}
And it just gives me a blank page (ERR_CONNECTION_RESET). I have nothing to try to fix it since there is no error, I don't know how to debug this.
When I try to run this simple test code (https://stackoverflow.com/a/15501449/3070307) outside of Symfony, it works fine.
Any help is much appreciated.
EDIT:
Ok two things:
sleep(100);
Sleeps for 100 seconds... I miss-typed usleep.
Second, the Symfony cache is messing with thread execution apprently, disabling it fixed it (http://symfony.com/doc/current/cookbook/debugging.html).
The only remaining problem is the render function does nothing, I'm not even sure it's called.
During debug, I'm experiencing a problem where any function call within my Controller action method will throw an exception, but when running the code without the debugger, it does not occur. I am using Xdebug 2.2.3, with Yii framework 1.1.14.
My Controller class is called TesterController, and this happens in the actionIndex:
class Controller extends CController
{
public $layout='//layouts/column1';
public $menu=array();
public $breadcrumbs=array();
}
class TesterController extends Controller {
public function actionIndex() {
printf("test\n");
$this->render('index');
}
}
When attempting to step into the printf function, execution goes to the following Yii exception handler:
public function handleException($exception)
{
// disable error capturing to avoid recursive errors
restore_error_handler();
restore_exception_handler();
...
where $exception complains that property TesterController.email does not exist. I've tried viewing the stack and exception traces, updating to the latest version of Xdebug, updating to the latest version of Yii, deleting all cache, grepping my code for any references to this property (email), and recreating my Controller and View classes from scratch to no avail. I've reduced it to this minimal demonstrable case, and I'm at a loss for what to try next besides rebuilding my Yii installation from scratch. Something tells me it might be related to PHP magic getters. Any insight would be greatly appreciated.
