first of all we need to get fresh Laravel 6 version application using bellow command, So open your terminal OR command prompt and run bellow command:
Step 2: Database Configuration
In second step, we will make database configuration for example database name, username, password etc for our crud application of laravel 6. So let's open .env file and fill all details like as bellow:
In this step, we will create new migration for adding new column for "role". we will take enum datatype for role column. we will take only "user", "manager" and "admin" value on that. we will keep "user" as default value.
so let's create as like bellow:
After this command you will find one file in following path "database/migrations" and you have to put bellow code in your migration file for create products table.
Now you have to run this migration by following command:
Step 4: Add Some Dummy Users
You need to add some dummy users to users table as like bellow screen shot:
You have to follow few step to make auth in your laravel 6 application.
First you need to install laravel/ui package as like bellow:
Here, we need to generate auth scaffolding in laravel 6 using laravel ui command. so, let's generate it by bellow command:
Now you need to run npm command, otherwise you can not see better layout of login and register page.
Install NPM:
Run NPM:
Step 6: Define Custom Gates
In this step, we will define custom gate for user role access. we will define "user", "manager" and "admin" user. So let's update AuthServiceProvider.php file as like bellow:
app/Providers/AuthServiceProvider.php
Step 7: Use Gates
Now, we will user our custom gate in our blade file. i created three button for each roles. When user will login then user will see only user button and same way others.
So, let's update your home file as like bellow:
resources/views/home.blade.php
Now we can run our application.
Now you can test it by using following command:
You can login with each user and output will be as like bellow:
User Login
Manager Login
Admin Login
Gates in Controller:
You can also check in Controller file as like bellow:
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Gate;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*/
public function register(): void
{
//
}
/**
* Bootstrap any application services.
*/
public function boot(): void
{
/* define a admin user role */
Gate::define('isAdmin', function ($user) {
return $user->role == 'admin';
});
/* define a manager user role */
Gate::define('isManager', function ($user) {
return $user->role == 'manager';
});
/* define a user role */
Gate::define('isUser', function ($user) {
return $user->role == 'user';
});
}
}
