In my Laravel 4 app, I have custom class sCAPTCHA in app/custom_libs/scaptcha/sCAPTCHA.php
class sCAPTCHA
{
public Create()
{
//.....some code
Session::put('sCAPTCHA_code',$code);
then in the controller ScaptchaController
$scaptcha = new sCAPTCHA();
$scaptcha->Create();
and Laravel 4 throw me an error:
Class 'scaptcha\Session' not found
It's very clear error, but how can I implement Session class of Laravel in my custom class sCAPTCHA?
I figured it out:
use Illuminate\Support\Facades\Session;
class sCAPTCHA
{
and now is working fine :)

Peeps, I'm lost. Tried everything and after 5 hours of searching through the 10th page of Google hits, I give up. Maybe I just dont know how to ask Google the correct keywords..
I have this scenario: In lumen app, lets call it X, I have require custom packages CRUD and Storage, Storage is using functionality of CRUD.
StorageService has:
use Crud\Services\BaseService;
class StorageService extends BaseService{}
And Crud\BaseService has constructor, that uses Model:
use Illuminate\Database\Eloquent\Model;
class BaseService
{
protected $model;
public function __construct(Model $model)
{
$this->model = $model;
}
}
When I try to do anything with my app X, I get error:
Target [Illuminate\Database\Eloquent\Model] is not instantiable while building [Lumee\Storage\Services\StorageService]
I cannot get my head around how to get to proper class of Model, since I saw, that Model is abstract class.
Also, I'm using this CRUD package successfully in another App, only difference is, there CRUD is used directly in app, not via some other package. I'm confused, why there is working without any additional bindings and service registering..
EDIT: Added some binding into StorageServiceProvider (boot and register methods):
$this->app->bind(BaseService::class, function(){
return new BaseService(new Model());
});
And registered StorageServiceProvider in my boostrap/app.php:
$app->register(Storage\Providers\StorageServiceProvider::class);
Thing still returns same error. I tried with binding in CrudServiceProvider, nope.
you can't get object from abstract class (Model class) to solve this try this :
use Illuminate\Database\Eloquent\Model;
class BaseService
{
protected $model;
}
suppose your model is (Storage) :
use Crud\Services\BaseService;
class StorageService extends BaseService{
public function __construct(Storage $model)
{
$this->model = $model;
}
}
In the Laravel documentation, I found the following - https://laravel.com/docs/5.4/container#the-make-method
but I am still confused as to what exactly the make() method does. I know the create() method uses the make() method and then persists them into the database, so does make() methods just temporarily save it in php tinker or something? Sorry, I'm Laravel noob. I'm trying to figure out these functions. Thank you! :)
The make method will return an instance of the class or interface you request.
Where you request to make an interface, Laravel will lookup a binding for that interface to a concrete class.
E.g.
$app->make('App\Services\MyService'); // new \App\Services\MyService.
One advantage to using the make method, is that Laravel will automatically inject any dependencies the class may define in it's constructor.
E.g. an instance of the Mailer class would be automatically injected here.
namespace App\Services;
use \Illuminate\Mail\Mailer;
class MyService
{
public function __construct(Mailer $mailer) {
$this->mailer = new Mailer;
}
}
I discovered recently that when you use make (), you are installing the class and you can access the methods of that class or model, this is a useful for the Test and validate that you are getting what you want Example:
User model
class User extends Authenticatable
{
public function getRouteKeyName ()
{
return 'name';
}
}
Test user
class UserTest extends TestCase
{
public function route_key_name_is_set_to_name ()
{
$ user = factory (User :: class) -> make ();
$ this-> assertEquals ('name', $ user-> getRouteKeyName ());
// When you access the getRouteKeyName method you get the return, that is 'name'
}
}
On the other hand if you use "create" that would give an error because you are creating a user
How to call a model in laravel.
My code is:
use Jacopo\Authentication\Models\Guide;
class SampleController extends BaseController
{
public function index()
{
$model='Guide';
$guide=$model::where('guide_link','=',"guide")->get();
print_r($guide);
}
}
This will produce Class 'Guide' not found error.
If you added your class you should run in terminal
composer dump-autoload
to update your class map. Otherwise autoloader may not "see" your class and you are getting this error.
You need to add the namespace to your string:
class SampleController extends BaseController
{
public function index()
{
$model='Jacopo\Authentication\Models\Guide';
$guide=$model::where('guide_link','=',"guide")->get();
print_r($guide);
}
}
You could also resolve it from the IoC container, but you need to register it first:
App::bind('Guide', 'Jacopo\Authentication\Models\Guide');
And then you should be able to:
$model = App::make('Guide');
$guide = $model::where('guide_link','=',"guide")->get();
But this is not a very good option
i am a beginner to laravel 4 framework.can any body help me why the following code showing an error when i am running it in the browser.
authors.php in controller
<?php
class Authors_Controller extends Base_Controller{
public $restful = true;
public function get_index(){
return View::make('authors.index');
}
}
routes.php
Route::get('authors',array('uses' => 'authors#index'));
can anybody suggest me a good video tutorial to learn laravel 4 clearly
You are extending the wrong class, based on the fact you are using laravel version 4.
Docs: http://laravel.com/docs/controllers#basic-controllers
class UserController extends BaseController {
I have the below code in the controller.
class Authors_Controller extends Base_Controller {
public $restful = true;
public function get_index() {
return View::make('authors.index');
}
}
When i run in the browser, i am getting the error,
class 'base_controller' not found
Change
class Authors_Controller extends Base_Controller {
to
class AuthorsController extends BaseController {
Edit: you might need to leave it as "Authors_Controller" depending how your file is named - but you should change it to the Laravel 4 convention of "AuthorsController"
In addition to The Shift Exchange's answer. You might also want to rename your function to getIndex, and rename your controller to AuthorsController as Laravel 4 is camelCased.
