Database Migration & Model View Controller

Model:

• A Model is a file that describes 1 database table.
• It should be a singular form of the database table.
• It extends the Model class means it ties to the Database and ready to use.

class Category extends Model
{
    use HasFactory;

}

Controller:

• It is a bridge that gets data from the database and passed it into the views.
• It also takes data from the view (shape of HTML Forms) and stored in the data.

class HomeController extends Controller
{
    public function index()
    {
        // This will get all the records from the categories table
        // and every record is an object and passed into the view
        $allCategories = Category::all();
        return view('index', compact('allCategories'));
    }
}

View:

• Represents presentation layer of our application.

<div class="list-group">
      @foreach($allCategories as $category)
          <a href="/?category_id={{ $category->id }}" class="list-group-item">{{ $category->name }}</a>
      @endforeach
</div>
