How to set Permission module on Laravel

How to setup Permission Module in Laravel

PHP Feb 3, 2023 0 371 Add to Reading List

1) With help of packages

In Laravel, you can integrate the permission module by using a package such as Spatie's Laravel Permission package. Here are the steps to install and use the package:

Install the package:

composer require spatie/laravel-permission

Publish the migrations:

php artisan vendor:publish --provider="Spatie\Permission\PermissionServiceProvider" --tag="migrations"

Run the migrations:

php artisan migrate

Use the HasRoles trait in your User model:

use Spatie\Permission\Traits\HasRoles; class User extends Authenticatable { use HasRoles; }

Define the permissions and assign them to roles:

use Spatie\Permission\Models\Permission;

use Spatie\Permission\Models\Role;

$permission = Permission::create(['name' => 'edit articles']);

$role = Role::create(['name' => 'writer']);

$role->givePermissionTo($permission);

$user->assignRole('writer');

Check if a user has a permission:

if ($user->can('edit articles')) {

// The user can edit articles...

}

This is a brief overview of integrating the permission module in Laravel using the Spatie's Laravel Permission package. You can find more information and advanced usage in the official documentation: https://docs.spatie.be/laravel-permission/v3/introduction/

2) How to do it manually?

To implement permissions in Laravel manually, you can use Laravel's built-in authorization features and create your own custom solution. Here are the steps to do this:

1. Create a migration to add a roles table that will store the roles for each user:php artisan make:migration create_roles_table

php artisan make:migration create_roles_table

2. Add the necessary fields to the roles table, such as id, name, and description:

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateRolesTable extends Migration
{
    public function up()
    {
        Schema::create('roles', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->string('description')->nullable();
        $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('roles');
    }
}

3. Create a migration to add a permissions table that will store the permissions for each role:

php artisan make:migration create_permissions_table

4. Add the necessary fields to the permissions table, such as id, name, and description:

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreatePermissionsTable extends Migration
{
    public function up()
    {
        Schema::create('permissions', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('description')->nullable();
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('permissions');
    }
}

5. Create a migration to add a pivot table to connect roles and permissions:

php artisan make:migration create_role_permission_table

6. Add the necessary fields to the pivot table, such as role_id and permission_id:

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateRolePermissionTable extends Migration
{
    public function up()
    {
        Schema::create('role_permission', function (Blueprint $table) {
            $table->unsignedInteger('role_id');
            $table->unsignedInteger('permission_id');
            $table->timestamps();

            $table->primary(['role_id', 'permission_id']);
            $table->foreign('role_id')->references('id')->on('roles')->onDelete('cascade');
            $table->foreign('permission_id')->references('id')->on('permissions')->onDelete('cascade');
        });
    }
}
