Zero Configuration laravel Role Permission Setup 🔥🤩

#laravel #php #opensource #webdev

This package provides an effortless way to manage roles and permissions in your Laravel application. With automatic database configuration, one-command publishing, and easy integration, you can quickly set up robust role-based access control without hassle.

Getting Started

composer require erag/laravel-role-permission

Step 1: Add Trait to User Model

Before configuring the database and publishing the role-permission files, add the HasPermissionsTrait to define in your User model. This trait is essential for handling roles and permissions in your application.

HasPermissionsTrait

<?php

namespace App\Models;

use EragPermission\Traits\HasPermissionsTrait;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class User extends Authenticatable
{
    use HasFactory, HasPermissionsTrait, Notifiable;

}

Step 2: Database Configuration

Before proceeding with the setup, ensure that your database connection is properly configured in your .env file. Example configuration:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name
DB_USERNAME=your_database_user
DB_PASSWORD=your_database_password

Make sure to replace your_database_name, your_database_user, and your_database_password with your actual database credentials.

Step 3: Automatic Database Setup

After configuring your database connection, the package will automatically set up your database by running the necessary migrations and seeders without any additional setup.

Step 4: Register the Service Provider

For Laravel v11.x

Ensure the service provider is registered in your /bootstrap/providers.php file:

return [
    // ...
    EragPermission\PermissionServiceProvider::class,
];

For Laravel v10.x

Ensure the service provider is registered in your config/app.php file:

'providers' => [
    // ...
    EragPermission\PermissionServiceProvider::class,
],

Step 5: Publish Role-Permission Files

Once the database is configured, publish the required migration and model files with a single command:

php artisan erag:publish-permission

This command will publish the required migrations:

php artisan erag:publish-permission --migrate

If you want to run the published migrations and seed the datbase you cann add --migrate and --seed respectively. Then the command will automatically run the migrations and the seeder to set up roles and permissions in your database.

php artisan erag:publish-permission --migrate --seed

Step 6: Using Role-Based Permissions

You can now easily check user permissions within your application logic:

if (auth()->user()->can('permission_name')) {
    // The user has the specified permission
}

You can also use the helper method:

if (hasPermissions('post-create')) {
    dd('You are allowed to access');
} else {
    dd('You are not allowed to access');
}

if (hasPermissions('post-create|post-edit')) {
    dd('You are allowed to access');
} else {
    dd('You are not allowed to access');
}

if (hasPermissions('post-create,post-edit')) {
    dd('You are allowed to access');
} else {
    dd('You are not allowed to access');
}

To get all permissions:

getPermissions();

Using Role-Based Checks

if (hasRole('admin')) {
    dd('You are allowed to access');
} else {
    dd('You are not allowed to access');
}

To get all roles:

getRoles();

Step 7: Protecting Routes with Middleware

To protect routes based on roles and permissions, you can use the provided middleware. For example, to allow only users with the user role and create-user permission:


Route::group(['middleware' => ['role:user,user-create']], function () {
    // Protected routes go here
});

Route::group(['middleware' => ['role:admin,post-create']], function () {
    // Protected routes go here
});

Step 8: Displaying Content Based on Roles

You can also use Blade directives to display content based on the user's role:

@role('admin')
    {{ __('You are an admin') }}
@endrole

@role('user')
    {{ __('You are a user') }}
@endrole

Step 9: Displaying Content Based on Permissions

You can also use Blade directives to display content based on the user's permissions:

@hasPermissions('post-create')
    {{ __('You can create a post') }}
@endhasPermissions

@hasPermissions('post-create|post-edit')
    {{ __('You can create a post') }}
@endhasPermissions

@hasPermissions('post-create,post-edit')
    {{ __('You can create a post') }}
@endhasPermissions

Example Seeder for Roles and Permissions

Here's an example RolePermissionSeeder that seeds roles, permissions, and users:

<?php

namespace Database\Seeders;

use App\Models\User;
use EragPermission\Models\Role;
use EragPermission\Models\Permission;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Hash;

class RolePermissionSeeder extends Seeder
{
    /**
     * Run the database seeds.
     */
    public function run(): void
    {
        DB::transaction(function () {
            $this->seedPermissions();
            $this->seedRoles();
            $this->seedUsers();
        });
    }

    private function seedPermissions(): void
    {
        $permissions = [
            'post-create',
            'user-create',
        ];

        foreach ($permissions as $permissionName) {
            Permission::firstOrCreate(['name' => $permissionName]);
        }
    }

    private function seedRoles(): void
    {
        $roles = [
            'admin' => ['post-create', 'post-edit', 'post-delete', 'post-update'],
            'user' => ['user-create', 'user-edit', 'user-delete', 'user-update'],
        ];

        foreach ($roles as $roleName => $permissionNames) {
            $role = Role::firstOrCreate(['name' => $roleName]);

            foreach ($permissionNames as $permissionName) {
                $permission = Permission::firstOrCreate(['name' => $permissionName]);
                $role->permissions()->syncWithoutDetaching($permission);
                $permission->roles()->syncWithoutDetaching($role);
            }
        }
    }

    private function seedUsers(): void
    {
        $users = [
            [
                'name' => 'Admin',
                'email' => 'admin@gmail.com',
                'password' => Hash::make('admin'),
                'roles' => ['admin'],
                'permissions' => ['post-create', 'post-edit'],
            ],
            [
                'name' => 'User',
                'email' => 'user@gmail.com',
                'password' => Hash::make('user'),
                'roles' => ['user'],
                'permissions' => ['user-create', 'user-edit'],
            ],
        ];

        foreach ($users as $userData) {
            $user = User::updateOrCreate(
                ['email' => $userData['email']],
                [
                    'name' => $userData['name'],
                    'password' => $userData['password'],
                ]
            );

            foreach ($userData['roles'] as $roleName) {
                $role = Role::where('name', $roleName)->first();
                if ($role) {
                    $user->roles()->syncWithoutDetaching($role);
                }
            }

            foreach ($userData['permissions'] as $permissionName) {
                $permission = Permission::where('name', $permissionName)->first();
                if ($permission) {
                    $user->permissions()->syncWithoutDetaching($permission);
                }
            }
        }
    }
}
