    DocumentRoot /var/www/html/code/public

    <Directory /var/www/html/code/public>
        AllowOverride All
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

sudo nano /etc/apache2/ports.conf
Listen 8082

sudo a2ensite laravel.conf
sudo service apache2 restart

Auth

Enable Authentication

php artisan make:auth

DB access

.env
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

create database homestead;
grant all privileges on homestead.* to homestead@localhost identified by 'secret';

Site Creation

ROUTES

cd routes/
sudo nano web.php

Route::get('contact', function () {
    return 'Hello from Aman';
});

Route::get('contact/{category}', function ($category) {
    return 'Hello from '.$category. ' Aman';
});

Check resulting pages:

http://192.168.1.35/hello/public/contact/
http://192.168.1.35/hello/public/contact/Test

CONTROLLERS

Routes page can have URLS but this is for small Apps only for Industrial ones, use Controllers

sudo php artisan make:controller RecordController

cd app/Http/Controllers/ sudo nano RecordController.php

class RecordController extends Controller {

 public function showAll()
       {
               return view('view');
       }

 public function showNew()
       {
               return view('new');
       }

 public function showEdit()
       {
               return view('edit');
       }

}

cd ../../routes/ aman@ubuntu:/var/www/html/hello/routes$ sudo nano web.php

Route::get('/view', 'RecordController@showAll');

Route::get('/new', 'RecordController@showNew');

Route::get('/edit', 'RecordController@showEdit');

DATABASE

Create new DB: hello

sudo nano .env

~add DB credentials

Create a DB table using Artisan:

sudo php artisan make:migration create_records_table

Created Migration: 2017_09_19_190352_create_records_table

cd database/migrations/ aman@ubuntu:/var/www/html/hello/database/migrations$ ls 2017_09_19_190352_create_records_table.php

Easy to create tables with Migrations Easy to manage them in large environments,

sudo nano 2017_09_19_190352_create_records_table.php

   public function up()
   {
       Schema::create('records', function (Blueprint $table) {
           $table->increments('id');
           $table->string('country');
           $table->string('city');
           $table->string('date');
           $table->string('no_of_aliens');
           $table->string('color_of_aliens');
           $table->timestamps();
       });

   /**
    * Reverse the migrations.
    *
    * @return void
    */
   public function down()
   {
       Schema::dropIfExists('records');
   }

sudo php artisan migrate

ELOQUENT

sudo php artisan make:model Record

cd app/

sudo nano Record.php

class Record extends Model {

   protected $table='records';
   protected $fillable=['id','country','city','date','no_of_aliens','color_of_aliens'];

}

Feed test data using Seeding:

create seed file:

sudo php artisan make:seeder RecordsTableSeeder

cd database/seeds/ aman@ubuntu:/var/www/html/hello/database/seeds$ sudo nano RecordsTableSeeder.php

use App\Record; //to import records.php file

class RecordsTableSeeder extends Seeder {

 public function run()
   {
      for ($i=0; $i<20; $i++)
       {
          Record::create
           (
               [
                  'country' => "country$i",
                  'city' => "city$i",
                  'date' => "date$i",
                  'no_of_aliens' => "no_of_aliens$i",
                  'color_of_aliens' => "color_of_aliens$i"
               ]
           );
       }
   }

}

sudo nano DatabaseSeeder.php

use App\Record;

class DatabaseSeeder extends Seeder {

   public function run()
   {
       $this->call('RecordsTableSeeder');
   }

}

aman@ubuntu:/var/www/html/hello$ sudo php artisan db:seed

Seeding: RecordsTableSeeder
