How to Implement Authorization using Gates in Laravel 6
In this article, I’m going to share how to implement authorization using gates in Laravel 6. Let’s start:

- Install Laravel and Basic Configurations
- Generate Auth Scaffolding
- Add Role to User Table
- Create Custom Gates
- Use Gates in View
- Use Gates in Controller
- Use in Route with Middleware
Step 1 : Install Laravel and Basic Configurations
Each Laravel project needs this thing. That’s why I have written an article on this topic. Please see this part from here: Install Laravel and Basic Configurations.
Step 2 : Generate Auth Scaffolding
To generate auth scaffolding, we need to install the laravel/ui package:
composer require laravel/ui
Now we’re able to generate auth scaffolding in Laravel 6 using this command:
php artisan ui bootstrap --auth
To see good UI, we need to run this last command:
npm install && npm run dev
Step 3 : Add Role to User Table
After setting up basic configurations, let’s add role column in the user name. We’re going to define 2 roles: admin & user. Run this command to create a migration file:
php artisan make:migration add_role_column_to_users_table
Go to database/migrations
folder and open the newly created migration file and update the up()
function like this:
public function up()
{
Schema::table('users', function (Blueprint $table) {
$table->enum('role', ['admin', 'user'])->default('user');
});
}
We’ve set the user role as default. Now migrate the migrations:
php artisan migrate
Let’s insert 2 dummy user data using Laravel Tinker:
# open tinker console
php artisan tinker
# insert 2 data
factory(App\User::class, 2)->create();
After inserting data, from the phpMyAdmin set role to the dummy users.

Step 4 : Create Custom Gates
Now we’re going to define 2 gates for the 2 roles. Navigate to app/Providers
folder and open AuthServiceProvider.php file & let’s set gates in boot()
function.
public function boot()
{
$this->registerPolicies();
// define admin role
Gate::define('isAdmin', function($user) {
return $user->role == 'admin';
});
// define user role
Gate::define('isUser', function($user) {
return $user->role == 'user';
});
}
Step 5 : Use Gates in View
We can use gates in view easily. The syntax is:
@can('isAdmin')
Your role: Admin!
@elsecan('isUser')
Your role: User!
@endcan
Let’s set gates in the dashboard blade file. Open resources/views/home.blade.php
and update with this code:
@extends('layouts.app')
@section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">Dashboard</div>
<div class="card-body">
@if (session('status'))
<div class="alert alert-success" role="alert">
{{ session('status') }}
</div>
@endif
You are logged in.
@can('isAdmin')
Your role: Admin!
@elsecan('isUser')
Your role: User!
@endcan
</div>
</div>
</div>
</div>
</div>
@endsection
Admin role:

User role:

Step 6 : Use Gates in Controller
Like the view, we can use gates in the controller too. I’m showing some uses.
public function functionName()
{
// allows
if (Gate::allows('isAdmin')) {
dd('Admin area');
} else {
dd('Your role is not Admin');
}
// denies
if (Gate::denies('isAdmin')) {
dd('Your role is not Admin');
} else {
dd('Admin area');
}
}
Step 7 : Use in Route with Middleware
Like view & controller, we’re able to use gates in route with middleware. Here’s the example:
Route::get('settings', function () {
return "This route is for admin role only";
})->middleware('can:isAdmin');
Route::get('profile', function () {
return "This route is for user role only";
})->middleware('can:isUser');

Links
You can add links by adding text inside of [] and the link inside of (), like so:
Lists
To add a numbered list you can simply start with a number and a ., like so:
1. The first item in my list
For an unordered list, you can add a dash -, like so:
- The start of my list
Images
You can add images by selecting the image icon, which will upload and add an image to the editor, or you can manually add the image by adding an exclamation !, followed by the alt text inside of [], and the image URL inside of (), like so:
Dividers
To add a divider you can add three dashes or three asterisks:
--- or ***
