Laravel 8 CRUD Tutorial by Example

 


#Laravel is one of the most popular PHP-based frameworks for creating database-driven apps.

#laravel8 #CRUD #EXAMPLE

Step 1 — Installing Laravel 8

Let's get started by installing Laravel 8 using Composer.

Open a new command-line interface and run the following command:

$ composer create-project laravel/laravel=8.0 laravel8app --prefer-dis   

Step 2 — Setting up a MySQL Database
Let's now create a MySQL database that we'll use to persist data in our Laravel application. In your terminal, run the following command to run the mysql client:
$ mysql -u root -p

When prompted, enter the password for your MySQL server when you've installed it.
Next, run the following SQL statement to create a db database:
mysql> create database db;

Open the .env file and update the credentials to access your MySQL database:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db
DB_USERNAME=root
DB_PASSWORD=******

You need to provide the database name, the username and password.
At this point, you can run the migrate command to create your database and a bunch of SQL tables needed by Laravel:
$ php artisan migrate

Note: You can run the migrate command at any other points of your development to add other SQL tables in your database or to later your database if you need to add any changes later.
Step 3 — Creating a Database Migration
We'll be creating a CRUD application with Laravel 8 for a products app so we'll need to create the corresponding SQL table in the database using a migration.
Head back to your terminal and run the following commands:
$ cd laravel8app
$ php artisan make:migration create_products_table --create=products

A migration file will be created inside the database/migrations folder of your product, next we need to add the fields to our database table. A product will have a name, description, price, date created, and date updated.
Open the 2020_09_12_222716_create_products_table.php file that contains the migration class and update it as follows:
<?php

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

class CreateProductsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->string('name', 255)->nullable();
            $table->string('description', 500)->nullable();
            $table->decimal('price', 22)->nullable()->default(0.00);
            $table->timestamp('created_at')->useCurrent();
            $table->timestamp('updated_at')->nullable();
        });
    }

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

To avoid running into errors, you need to specify the default string length before running your migration.
Open the app/Providers/AppServiceProvider.php file and add Schema::defaultstringLength(191) as follows:
<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;


class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }

    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        Schema::defaultStringLength(191);
    }
}

Next, head back to your terminal and run the following command:
$ php artisan migrate

This will add the fields to our database table.
Step 4 — Adding a Resource Route
After creating our database table using a Laravel 8 migration. We'll next need to add routes for our CRUD operations.
Open the routes\web.php file and add our resource route as follows:
<?php

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

Route::get('/', function () {
    return view('welcome');
});


Route::resource('products', ProductController::class);

Step 5 — Adding a Laravel 8 Controller and Model
Next, we need to create a Laravel controller and model by running the following command:
$ php artisan make:controller ProductController --resource --model=Product

You'll be prompted if you want to create the Product model because it does not exist. Type yes and it will create the model and controller.
Open the app/Http/Controllers/ProductController.php file and update it as follows:
<?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', compact('products'))
            ->with('i', (request()->input('page', 1) - 1) * 5);
    }

    /**
     * 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)
    {
        $request->validate([
            'name' => 'required',
            'description' => 'required',
            'price' => 'required'
        ]);

        Product::create($request->all());

        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)
    {
        $request->validate([
            'name' => 'required',
            'description' => 'required',
            'price' => 'required'
        ]);
        $product->update($request->all());

        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');
    }
}



Laravel 8 makes use of a Models folder for storing model files.
Open the app/Models/Product.php, add the following functions and the fillable, the fillable are the fields in the database that a user can fill:
<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    use HasFactory;

    protected $table = 'products';
    public $timestamps = true;

    protected $casts = [
        'price' => 'float'
    ];

    protected $fillable = [
        'name',
        'description',
        'price',
        'created_at'
    ];
}


Step 6 — Adding your Larevl 8 Blade Views
Laravel makes use of the blade templating system for views.
Inside the resources/views folder, create two Layouts and Products folders.
Update yhe Layouts/App.blade.php file with the following content:
<html>

<head>
    <title>App Name - @yield('title')</title>

    <!-- Bootstrap -->
    <link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha/css/bootstrap.css" rel="stylesheet">

    <!-- Font Awesome JS -->
    <script defer src="https://use.fontawesome.com/releases/v5.0.13/js/solid.js"

    </script>

    <style>
        .footer {
            position: fixed;
            left: 0;
            bottom: 0;
            width: 100%;
            background-color: #9C27B0;
            color: white;
            text-align: center;
        }

    </style>

</head>

<body>
    @section('sidebar')

    @show

    <div class="container">
        @yield('content')
    </div>
</body>

</html>


Open the Index.blade.php and update it as follows:
@extends('layouts.app')

@section('content')
    <div class="row">
        <div class="col-lg-12 margin-tb">
            <div class="pull-left">

    </div>

    @if ($message = Session::get('success'))
        <div class="alert alert-success">
            <p></p>
        </div>
    @endif

    <table class="table table-bordered table-responsive-lg">
        <tr>
            <th>No</th>
            <th>Name</th>
            <th>description</th>
            <th>Price</th>
            <th>Date Created</th>
            <th>Actions</th>
        </tr>
        @foreach ($products as $product)
            <tr>
                <td></td>

                        @csrf
                        @method('DELETE')

                        <button type="submit" title="delete" style="border: none; background-color:transparent;">

That's it, we have finished implementing our Laravel 8 CRUD application.
You can serve your Laravel 8 application using the following command:
$ php artisan serve

You can access your app from http://127.0.0.1:8000.

Laravel 8 Auth (Registration and Login)

 

Laravel 8 Auth (Registration and Login)





Previously, in Laravel 7 and Laravel 6 in other to do user authentication, we use an artisan command composer require laravel/ui while from Laravel 5.9 downwards uses php artisan make:auth

In Laravel 8, there is a major change in that area in the sense that many things are introduced and a lot of configurations have been done to get you started and not minding the boilerplate of your application, one of those changes is the introduction of Jetstream, Laravel Jetstream is a beautifully designed application scaffolding for Laravel. A major shift from the legacy authentication UI of Laravel.

Step 1: Install a new Laravel app

composer create-project laravel/laravel projectapp --prefer-dist

The command above only install Laravel, however, if you want to install Jetstream together then either


Laravel new projectapp --jet

or

composer require laravel/jetstream

we are going with the first of only installing Laravel, I want to explain other things in the process.

Before we migrate, let’s catch one bug before it throws an error, go to App/Providers/AppServiceProvider.php
and add

Schema::defaultstringLength(191);

to the boot function, also add

use Illuminate\Support\Facades\Schema;

to the top

Step 3: Migration

php artisan migrate

migration file

Step 4: install Jetstream

composer require laravel/jetstream


Step 5: Install livewire or inertia

We need to install one of the stacks, either a livewire or an inertia stack, in this tutorial, I will only be using livewire because it set up everything I need for the app

php artisan jetstream:install livewire 


As suggested, run npm install && npm run dev to build all the javaScript files and CSS we need for our app. On successful build, Laravel will send a notification at the bottom left.


Step 5: Migrate the new table that is created

php artisan migrate


Let’s run our app

php artisan serve
