Laravel 5 custom package class not found

Question

I am creating laravel 5.2 package, following are my files

packages/
-Shreeji/
--Ring/
---composer.json
---src/
----Ring.php
----RingModel.php
----RingServiceProvider

composer.json

{
 "name": "shreeji/ring",
 "description": "Simple",
 "license": "MIT",
 "authors": [
     {
         "name": "author",
         "email": "email@gmail.com"
     }
 ],
 "autoload": {
        "psr-4": {
             "Shreeji\\Ring\\": "src/"
         }
     },
 "minimum-stability": "dev",
 "require": {
     "Illuminate/support": "~5"
 }
}

Ring.php

namespace Shreeji\Ring;

use Illuminate\Http\Response;

Class Ring {

private $ringmodel;
protected $table_name = null;


function __construct() {

}

function set_table($table_name)
{
    $this->table_name = $table_name;
    $this->ringmodel = New RingModel($this->table_name);
    return $this;
}

}

RingModel.php

use \Illuminate\Database\Eloquent\Model as Eloquent;

class RingModel extends Eloquent {

// Set table name;
protected $table;
protected $primary_key;

public function __construct($table)
{
    $this->table = $table;
}
}

RingServiceProvider.php

namespace Shreeji\Ring;

use Illuminate\Support\ServiceProvider;

Class RingServiceProvider extends ServiceProvider
{
public function register()
{
    $this->app->bind('ring', function($app){
        return new Ring;
    });
}

public function boot()
{

}
}

And in app/Http/Controllers I have created test file like this

RingController.php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Shreeji\Ring;

class RingController extends Controller
{

 public function index()
 {
     $ring = New Ring();
     $ring->set_table('ring');
 }
}

In Routes.php

Route::get('ringtest', [ 'as' => 'ringtest', 'uses' => 'RingController@index' ]);

I have added service provider in config/app.php as

Shreeji\Ring\RingServiceProvider::class,

In composer.json I have added this as

.....
"psr-4": {
        "App\\": "app/",
        "Shreeji\\Ring\\": "packages/Shreeji/Ring/src"
    }
.....

When I call ringtest from browser I get following error.

FatalErrorException in RingController.php line 19: Class 'Shreeji\Ring' not found

What is wrong with my code why this class is not found I have also run composer dumpautoload.

Answer 1

Your namespaces are correct except when your importing the Ring class to your Ring controller

In your Ring controller change

use Shreeji\Ring;

to

use Shreeji\Ring\Ring;

where the first Ring is the folder and the second Ring is the class.

Next on the first line of your file add a namespace for your RingModel class

namespace Shreeji\Ring;

and add

use Shreeji\Ring\RingModel;

to the Ring class to import the RingModel class.

Then in your package's composer file change

"Shreeji\\Ring\\": "src/"

to

"Shreeji\\": "packages/shreeji/ring/src"

After that navigate to your package's directory and run

composer dump-autoload -o

in your terminal or command prompt to regenerate composer.json file .

Next add

"Shreeji\\": "packages/shreeji/ring/src"

to your Laravel application's composer.json file inside the autoload psr-4 array and then switch to your Laravel's application folder and run

composer dump-autoload -o

in your terminal or command prompt to regenerate composer.json file.

Answer 2

In your controller you have:

use Shreeji\Ring;

But, it must be:

use Shreeji\Ring\Ring;

The first 'Ring' is directory (namespace). The second 'Ring' is the class.

Your model is not in your namespace. The first line of your model must be:

namespace Shreeji\Ring;
