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
