CRUDの作成

CRUDの作成

環境構築

curl -s https://laravel.build/crud | bash
cd crud
./vendor/bin/sail up -d
vi config/app.php
以下を修正。
'timezone' => 'Asia/Tokyo', 'local' => 'ja',
./vendor/bin/sail composer require jeroennoten/laravel-adminlte
./vendor/bin/sail artisan adminlte:install
./vendor/bin/sail artisan make:migration
create_products_table createメソッドに追加
$table->string('name');
$table->integer('price');
./vendor/bin/sail artisan migrate
./vendor/bin/sail artisan make:model Product
./vendor/bin/sail artisan make:controller ProductController -r
※ -rはリソース用コントローラ
vi routes/web.php
use App\Http\Controllers\ProductController;
と
Route::resource('product', ProductController::class);
を追加。

一覧ページの作成

mkdir resources/views/product
touch resources/views/product/index.blade.php

@extends('adminlte::page')

@section('title', '商品一覧')

@section('content_header')
    <h1>商品一覧</h1>
@stop

@section('content')
    {{-- 完了メッセージ --}}
    @if (session('message'))
        <div class="alert alert-info alert-dismissible">
            <button type="button" class="close" data-dismiss="alert" aria-hidden="true">
                ×
            </button>
            {{ session('message') }}
        </div>
    @endif

    {{-- 新規登録画面へ --}}
    <a class="btn btn-primary mb-2" href="{{ route('product.create') }}" role="button">新規登録</a>

    <div class="card">

                        <th style="width: 70px"></th>
                    </tr>
                </thead>
                <tbody>

                        <tr>
                            <td>{{ $product->name }}</td>
                            {{-- 数字フォーマット --}}

                                    @csrf
                                    @method('DELETE')
                                    {{-- 簡易的に確認メッセージを表示 --}}

登録ページの作成
