# Seeder - seeding database with test data using seed classes

- Create seeding script

- How run all seeds
  php artisan db:seed
- Run individual seed
  php artisan db:seed --class= CustomerTableSeeder
- When need remove all tables, create all again and seed from the beginning,
  php artisan migrate:refresh --seed

# General utility functions

- To catch http request - $request->input('name', '<default value>');

# Tinker
- php artisan tinker
- When we need to print sql statement on tinker,
  DB::listen(function($query) { var_dump($query->sql); });

# Debugging techniques
- Write out executed SQLs
DB::listen(function ($query){
   var_dump($query->sql, $query->bindings);
});
- Log info
Log::info('some info'); // use Illuminate\Support\Facades\Log;

# General
- Clean up package: php artisan clear-compiled

- How add composer added packages to laravel:

- How create dummy records on tables
composer require fzaninotto/faker --dev : seems this is now ships with laravel package itself
