Laravel Concerns

The components that make up the Elnooronline's Laravel Projects.

Install

composer require elnooronline/laravel-concerns

Configuration

1. Import \Elnooronline\LaravelConcerns\Http\Controllers\Helpers trait in your base controller class

<?php

namespace App\Http\Controllers;

use Elnooronline\LaravelConcerns\Http\Controllers\Helpers;
...
class Controller extends BaseController
{
    use Helpers;
    ...
}

This feature enables to use flash() and getResourceName() methods.

• flash() : This method will set flash session with localed message.
  • example :

   public function store(Request $request)
   {
   	// Handle store
   
   	$this->>flash('created'); // returns : trans('%RESOURCE_NAME%.messages.created').
   
   	return view('home');
   }

• getResourceName() : This method returns the resource name of the specified crud used in Controller, Request, Model.
  • example : If you have UserController class will returns users. and you can add custom resource name by adding $resourceName property.

   class UserController extends Controller 
   {
   	public function index()
   	{
   		return $this->getResourceName();
   		// returns : users
   	}
   }
   class UserController extends Controller 
   {
   	/**
   	 * The controller resource name.
   	 *
   	 * @return string
   	 */
   	protected $resourceName = 'persons';
   	
   	public function index()
   	{
   		return $this->getResourceName();
   		// returns : persons
   	}
   }
  

2. All Request classes should extends \Elnooronline\LaravelConcerns\Http\RequestsFormRequest class.

API :

• getResourceName()
• parseLocale()
  • example :

   /**
    * Get the validation rules that apply to the request.
    *
    * @return array
    */
   public function rules()
   {
   	return $this->parseLocale([
   		'name:{default}' => 'required|string|max:255',
   		'name:{lang}' => 'nullable|string|max:255',
   	]);
   }
  

  insted of

   /**
    * Get the validation rules that apply to the request.
    *
    * @return array
    */
   public function rules()
   {
   	// The default locale is "en" in this example
   	return [
   		'name:en' => 'required|string|max:255',
   		'name:ar' => 'nullable|string|max:255',
   		'name:fr' => 'nullable|string|max:255',
   	];
   }
  

• getAproperRules()
  • example :

   /**
    * Get the validation rules that apply to the request.
    *
    * @return array
    */
   public function rules()
   {
   	return $this->getAproperRules();
   }
   
   /**
    * The rules of create request.
    *
    * @return array
    */
   public function createRules()
   {
   	return [];
   }
   
   /**
    * The rules of update request.
    *
    * @return array
    */
   public function updateRules()
   {
   	return [];
   }
  

Filterable

First you should use Filterable trait in your model.

namespace App\Models;

use Elnooronline\LaravelConcerns\Http\Filters\Filterable;
use Elnooronline\LaravelConcerns\Models\Abstracts\Authenticatable;

class User extends Authenticatable
{
    use Filterable;
    
    ...
}

Then run the following command to generate your filter class.

php artisan make:filter UserFilter

App\Http\Filters\UserFilter

<?php

namespace App\Http\Filters;

use Elnooronline\LaravelConcerns\Http\Filters\BaseFilters;

class UserFilter extends BaseFilters
{
    /**
     * Registered filters to operate upon.
     *
     * @var array
     */
    protected $filters = [
        'type',
        'created_at',
    ];
    
    /**
     * Filter the query by a given type.
     *
     * @param  string|int  $value
     * @return \Illuminate\Database\Eloquent\Builder
     */
    protected function type($value)
    {
        return $this->builder->where('type', $value);
    }

    /**
     * Filter the query by a given created at date.
     *
     * @param  string|int  $value
     * @return \Illuminate\Database\Eloquent\Builder
     */
    protected function createdAt($value)
    {
        return $this->builder->whereDate('created_at', $value);
    }
}

Now you can use the filter from controller.

Example Url : /users?type=admin

<?php

namespace App\Http\Controllers;

use App\Models\User;
use App\Http\Filters\UserFilter;
use Illuminate\Support\Facades\View;

class UserController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @param \App\Http\Filters\UserFilter $filter
     * @return \Illuminate\Http\Response
     */
    public function index(UserFilter $filter)
    {
        return View::make('users.index')
            ->withUsers(
                User::filter($filter)->latest()->paginate()
            );
    }
    
    ...
}

Eloquent Multiple Auth Provider

You should add 'eloquent.multiple' provider in your config/auth.php

'providers' => [
	'users' => [
		'driver' => 'eloquent.multiple',
		'model' => App\Models\User::class,
		'mapping' => [
			App\Models\User::ADMIN_TYPE => App\Models\Admin::class,
			App\Models\User::USER_TYPE => App\Models\User::class,
		],
	],

Add type column in users table.

Schema::table('users', function (Blueprint $table) {
	$table->string('type')->index();
});

In User model should add constants of user types.

class User extends Authenticatable
{
    /**
     * The code of normal user type.
     */
    const USER_TYPE = 'user';

    /**
     * The code of admin type.
     */
    const ADMIN_TYPE = 'admin';

Also you should use Elnooronline\LaravelConcerns\Models\Concerns\SingleTableInheritance trait in user model to fill type in creating event.

// User model

use Elnooronline\LaravelConcerns\Models\Concerns\SingleTableInheritance;

class User extends Authenticatable
{
    use SingleTableInheritance;

    /**
     * The type of the current model for single table inheritance.
     *
     * @var string
     */
    protected $modelType = 'user';
	...

// Admin Model

use Elnooronline\LaravelConcerns\Models\Scopes\UserTypeScope;
use Elnooronline\LaravelConcerns\Models\Concerns\SingleTableInheritance;

class Admin extends User
{
    use SingleTableInheritance;

    /**
     * The table associated with the model.
     *
     * @var string
     */
    protected $table = 'users';

    /**
     * The type of the current model for single table inheritance.
     *
     * @var string
     */
    protected $modelType = 'admin';

	/**
	 * The "booting" method of the model.
	 *
	 * @return void
	 */
	protected static function boot()
	{
		parent::boot();

		static::addGlobalScope(new UserTypeScope(static::ADMIN_TYPE));
	}
	...

The Elnooronline\LaravelConcerns\Models\Scopes\UserTypeScope used to determine the user type when use the model. and should be added to all user type models.

Now if your account type is admin will return App\Models\Admin instance when you call Auth::user() insted of App\Models\User.

Note : the App\Models\Admin model and other type models should extends App\Models\User model.
