Laravel 9 x CRUD with Tests

#webdev #tutorial #laravel

Hi there,

In this tutorial, we will see how to create a web application using Laravel version 9. We will build a application from scratch.

We will create a Product CRUD application.

We will use Bootstrap 5 for Styling.

Step 1: Create new Laravel application

Using the Laravel installer to create a new application.

laravel new shop-app
cd shop-app

Step 2: Database Configuration

We will update database configuration, we need to add database name, mysql username and password.

Open .env file and fill all details like as bellow:

file: .env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=blog
DB_USERNAME=root
DB_PASSWORD=""

Step 3: Create Migrations

Here, we will create products table using laravel migration. so let's use following command to create migration file.

php artisan make:migration create_products_table --create=products

A file in "database/migrations" will be generated

<?php
// ...
public function up() {
    Schema::create('products',  function  (Blueprint $table)  {
        $table->id();
        $table->string('name');
        $table->text('detail');
        $table->timestamps();
    });

}
// ....

php artisan migrate

Step 4: Create Controller and Model

We create a new resource controller named ProductController.

php artisan make:controller ProductController --resource --model=Product

A new file app/Http/Controllers/ProductController.php.

In this controller there will seven methods by default as bellow methods:

1) index()
2) create()
3) store()
4) show()
5) edit()
6) update()
7) destroy()

Copy code below and put on ProductController.php file.

file: app/Http/Controllers/ProductController.php

<?php

namespace App\Http\Controllers;

use App\Models\Product;
use Illuminate\Http\Request;

class ProductController extends Controller {

  /**
   * Display a listing of the resource.
   *
   * @return \Illuminate\Http\Response
   */
  public  function index()
  {

    $products = Product::latest()->paginate(5);

    return view('products.index')
      ->with('products',$products);

  }

  /**
   * Show the form for creating a new resource.
   *
   * @return \Illuminate\Http\Response
   */
  public  function create()
  {
    return view('products.create');
  }

  /**
   * Store a newly created resource in storage.
   *
   * @param  \Illuminate\Http\Request  $request
   * @return \Illuminate\Http\Response
   */
  public  function store(Request $request) {
    $data = $request->validate([
      'name'  =>  'required|string',
      'detail'  =>  'required|string',
    ]);
    Product::create($data);

    return redirect()->route('products.index')
      ->with('success','Product created successfully.');

  }

  /**
   * Display the specified resource.
   *
   * @param  \App\Models\Product  $product
   * @return \Illuminate\Http\Response
   */
  public  function show(Product $product) {

      return view('products.show',compact('product'));

  }

  /**
   * Show the form for editing the specified resource.
   *
   * @param  \App\Models\Product  $product
   * @return \Illuminate\Http\Response
   */
  public  function edit(Product $product) {

    return view('products.edit',compact('product'));

  }

  /**
   * Update the specified resource in storage.
   *
   * @param  \Illuminate\Http\Request  $request
   * @param  \App\Models\Product  $product
   * @return \Illuminate\Http\Response
   */
  public  function update(Request $request,  Product $product) {
    $data = $request->validate([
      'name'  =>  'required',
      'detail'  =>  'required',
    ]);

    $product->update($data);
    return redirect()->route('products.index')
      ->with('success','Product updated successfully');
  }

  /**
 * Remove the specified resource from storage.
 *
 * @param  \App\Models\Product  $product
 * @return \Illuminate\Http\Response
 */
  public  function destroy(Product $product) {

    $product->delete();
    return redirect()->route('products.index')
      ->with('success','Product deleted successfully');
  }

}

file: app/Models/Product.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{

  use HasFactory;

  protected $fillable = [
    'name', 
    'detail'
  ];

}

Step 5: Add Resource Route

Here, we need to add resource route for product crud.
Open your routes/web.php file and add following route.

file: routes/web.php

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ProductController;

// ...skippped
Route::resource('products',  ProductController::class);

Step 6: Add Blade Files

In last step. In this step we have to create just blade files. So mainly we have to create layout file and then create new folder "products" then create blade files of crud app. So finally you have to create following bellow blade file:

1). layout.blade.php
2). index.blade.php
3). create.blade.php
4). edit.blade.php
5). show.blade.php

So let's just create following file and put bellow code.

file: resources/views/products/layout.blade.php

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">

 <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">
    @yield('content')
</div>
</body>
</html>

file: resources/views/products/index.blade.php

@extends('products.layout')

@section('content')
  <div  class="row">
  <div  class="col-lg-12 margin-tb">
    <div  class="pull-left">
       <h2>Laravel Shop | All Products</h2>
    </div>
    <div  class="pull-right">
        <a  class="btn btn-success" href="{{ route('products.create') }}"> Create New Product</a>
    </div>
  </div>
  </div>
 @if ($message = Session::get('success'))
  <div  class="alert alert-success"> 
    <p>{{ $message }}</p>
  </div>
 @endif

  <table class="table table-bordered">
  <tr>
    <th>No.</th>
    <th>Name</th>
    <th>Details</th>
    <th width="280px">Action</th>
  </tr>
  @foreach ($products as $product)
  <tr>
    <td>{{ $loop->iteration }}</td>
    <td>{{ $product->name }}</td>
    <td>{{ $product->detail }}</td>
    <td>
    <form  action="{{ route('products.destroy',$product->id) }}" method="POST">
    <a class="btn btn-info" href="{{ route('products.show',$product->id) }}">Show</a>
    <a class="btn btn-primary" href="{{ route('products.edit',$product->id) }}">Edit</a>
       @csrf
       @method('DELETE')
     <button type="submit" class="btn btn-danger">Delete</button>
    </form>
    </td>
  </tr>
 @endforeach
  </table>
 {!! $products->links() !!}
