Entrust package provides a flexible way to add Role-based Permissions to your Laravel application.

This package creates four tables:

  1. Roles table: For storing role records
  2. Role_user table: For storing one-to-many relations between roles and users
  3. Permissions table: For storing permission records
  4. Permission_role table: For storing many-to-many relations between roles and permissions

Step 1: Install Entrust

open the composer.json in project and update the require object with entrust like this

OR

Open Terminal and run following command in root directory of your project

composer require zizaco/entrust:dev-master –no-update

Then Run

composer update

Step 2: Add Entrust Provider and Facades

Open up config/app.php, find the providers array and add the entrust provider:

Zizaco\Entrust\EntrustServiceProvider::class,

Find the aliases array and add the entrust facades:

‘Entrust’ => Zizaco\Entrust\EntrustFacade::class,

Then Run this command

php artisan vendor:publish
After this you will see a new file in config directory named entrust.php

If you want to use Middleware, You also need to add the following in the routeMiddleware array in app/Http/Kernel.php.

'role' => \Zizaco\Entrust\Middleware\EntrustRole::class,
'permission' => \Zizaco\Entrust\Middleware\EntrustPermission::class,
'ability' => \Zizaco\Entrust\Middleware\EntrustAbility::class,

Step 3: Now generate the Entrust migration:

php artisan entrust:migration

After the migration, four new tables will be present in the Database:
Roles, permissions, role_user, permission_role

Step 4: Create Models

1. Role Model

2. Permission Model

3. User Model

Now you can attach role to user at register time as per requirements like this:

Step 5 : Attaching roles and permissions

<?php
Route::get('/start', function()
{
$admin = new Role();
$admin->name = Admin;
$admin->save();

$customer = new Role();
$customer->name = ‘Customer’;
$customer->save();

$read = new Permission();
$read->name = 'can_read';
$read->display_name = 'Can Read Posts';
$read->save();

$edit = new Permission();
$edit->name = 'can_edit';
$edit->display_name = 'Can Edit Posts';
$edit->save();

$admin->attachPermission($read);
$customer->attachPermission($read);
$admin->attachPermission($edit);

$user1 = User::find(1);
$user2 = User::find(2);

$user1->attachRole($admin);
$user2->attachRole($customer);

return 'Woohoo!';
});

Now you can attach role to users at register time using this:

$user->roles()->attach(1);

To filter users according a specific role, you may use withRole() scope, for example to retrieve all admins:

$admins = User::withRole(‘admin’)->get();

Step 6 : Set Routes Role wise

Route::group(['middleware' => ['auth']], function()
{
Route::group(['prefix' => 'admin', 'middleware' => ['role:admin']], function() {
Route::get('/', 'AdminController@welcome');
});

Route::group(['prefix' => customer’, 'middleware' => ['role:customer']], function() {
Route::get('/', 'CustomerController@welcome');
});
});

Now you can access your project role wise.
