Question

我有一个名为CardsController的控制器和一个型号名称Card.I想知道当我在控制器中使用Card :: all（）时它与卡片db表的关系。不是其他表。我是laravel的新手。可能是某人建议我？

 cntroller: 

        <?php

            namespace App\Http\Controllers;

    use DB;
    use Illuminate\Http\Request;
    use App\card;
    class CardsController extends Controller
    {
        //
        public function index()
        {
            # code...
            // $cards = DB::table('cards')->get();
            $cards= card::all();
            return view('cards.index',compact('cards'));
        }

         public function show($id)
         {
            $cards = card::find($id);
            return view('cards.show',compact('cards'));
         }
    }

Model:


    <?php

    namespace App;

    use Illuminate\Database\Eloquent\Model;

    class card extends Model
    {
        //
    }

miggrations table:

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateCardsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('cards', function (Blueprint $table) {
            $table->increments('id');
            $table->string('title');
            $table->timestamps();
        });
    }

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

按照惯例，＆＃34; snake case＆＃34;，该类的复数名称将用作表名，除非明确指定了另一个名称。因此，在这种情况下，Eloquent将假设Flight模型将记录存储在航班表中。
