• https://laravel.com/docs/8.x/starter-kits (Starter Kits)
• Installation
• • laravel new <repo_name> (add --auth if you want Authentication ) if you have laravel install as a global package - composer global require laravel/installer
• • composer create-project --prefer-dist laravel/laravel <repo_name>
• Serve app by using php artisan serve --port=8081, if vhost is used, URL : http://blog.laravel.local:8081/
• Controllers located at app/Http/Controller/
• php artisan storage:link create symlink in <app_name>/public/ for <app_name>/storage/app/public/
• Routes routes/web.php - Auth & check role middleware
• Models are named singular and tables are created in plural
• Helpers :
• • In repo : Utils/helper.php
• • Added in composer.json - autoload section, then composer dump-autoload
• • Used in resources/views/admin/posts.blade.php
• Routes admin - adminPostEdit updated for multiple parameter
• php artisan route:list - Routes list

Auth package

• composer require laravel/ui for GUI
• Then php artisan ui:auth (get list by php artisan list)
• Files created : resources/views/auth & app/Http/Controllers/Auth
• Added middleware - app/Http/Middleware/CheckRole.php
• Register class in app/Http/Kernel.php

NPM / Laravel Mix

• Run npm install
• Some packages were missing, so npm install less-loader --save-dev & npm install stylus stylus-loader --save
• Then npm run dev
• Check webpack.mix.js & package.json

Database & Migrations

• config/database.php & .env hold DB connection details and type of database used
• Connect to MySQL CLI using command prompt by mysql -u <username> -p, then type your password.
• • show databases;
• • use your_database_name;
• • show tables;
• • desc your_table_name;
• php artisan make:model <NAME> - file created in app\Models and php artisan make:migrations <your_migration_name> - file created in database/migrations
• N.B - php artisan make:modeal <NAME> -m - create model & migration directly
• Create your table structure in the newly created migration

Schema::create('cars', function (Blueprint $table) {
    $table->increments('id');
    $table->string('model_name');
    $table->longText('information');
    $table->integer('year');
});

• After migrations are created, php artisan migrate OR php artisan migrate:install
• Might need to add fix in app\Providers\AppServiceProvider
• Some commands :
• • php artisan migrate:reset - rollback
• • php artisan migrate:refresh - rollback & migrate
• • php artisan migrate:status - Get information

Factory

• php artisan make:factory PostFactory --model=Post - create file in database/factories based on model argument
• Use of laravel/tinker by php artisan tinker for table population (N.B change protected $model in <NAME>Factory.php) and populate by :
• • \App\Models\User::factory()->count(5)->create(); - create 5 users (N.B Models should have use HasFactory;)
• • \App\Models\Post::factory()->count(7)->create(); - create 7 posts
• • \App\Models\Comment::factory()->count(15)->create(); - create 15 comments
• • \App\Models\Car::factory()->count(10)->create(); - create 10 cars

Query Builder

• Code in app/Http/Controllers/PubloicController.php, methods : carsList & carSingle
• More about DB in <project>\vendor\laravel\framework\src\Illuminate\Support\Facades\DB.php

Eloquent

• php artisan make:controller CarsController --resource - create controller with CRUD methods
• In web.php, add Route::resource('car-lists', \App\Http\Controllers\CarsController::class);, then routes will be created automatically
