Generate primary key from group keys, Tạo khóa chính từ khóa nhóm

C:\xampp82\htdocs\lva2\database\migrations\2023_10_06_020036_create_role_user_table.php

<?php

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

return new class extends Migration
{
  /**
   * Run the migrations.
   */
  public function up(): void
  {
    Schema::create('role_user', function (Blueprint $table) {
      $table->id();
      $table->unsignedInteger('role_id');
      $table->unsignedInteger('user_id');
      $table->primary(['role_id', 'user_id']);
    });
  }
  /**

  public function down(): void
  {
    Schema::dropIfExists('role_user');
  }
};

Facker slug

C:\xampp82\htdocs\testvn\database\migrations\2023_04_17_130047_create_posts_table.php

<?php

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

class CreatePostsTable extends Migration
{
  /**
   * Run the migrations.
   *
   * @return void
   */
  public function up()
  {
    Schema::create('posts', function (Blueprint $table) {
      $table->id();
      $table->string('detail');
      $table->string('slug');
      $table->timestamps();
    });
  }
  /**
   * Reverse the migrations.
   *
   * @return void
   */
  public function down()
  {
    Schema::dropIfExists('posts');
  }
}

C:\xampp82\htdocs\testvn\database\factories\PostFactory.php

<?php
namespace Database\Factories;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;
class PostFactory extends Factory
{
  /**
   * Define the model's default state.
   *
   * @return array
   */
  public function definition()
  {
    $detail = $this->faker->text(15);
    // $slug = str_slug($detail, '-');
    $slug = Str::slug($detail, '-');
    return [
      'detail'    => $detail,
      'slug'    => $slug
    ];

}

Cách thêm một cột vào một bảng cho trước

php artisan make:migration add_role_column_to_users_table

<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class AddRoleColumnToUsersTable extends Migration
{
  /**
   * Run the migrations.
   *
   * @return void
   */
  public function up()
  {
    Schema::table('users', function (Blueprint $table) {
      $table->enum('role',  ['user', 'manager', 'admin'])->default('user');
    });
  }
  /**
   * Reverse the migrations.
   *
   * @return void
   */
  public function down()
  {
  }
}

Sử dụng $table->unique dưới dạng mảng

C:\xampp82\htdocs\testcom\database\migrations\2023_04_04_023335_create_roles_table.php

<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration
{
  /**
   * Run the migrations.
   */
  public function up(): void
  {
    Schema::create('roles', function (Blueprint $table) {
      $table->id();
      $table->string('name');
      $table->string('guard_name');
      $table->timestamps();
      $table->unique(['name','guard_name']);
    });
  }
  /**
   * Reverse the migrations.
   */
  public function down(): void
  {
    Schema::dropIfExists('roles');
  }
};

Một cách sử dụng class tác riêng ra kết hợp database\seeders\DatabaseSeeder.php

C:\xampp82\htdocs\testfr\database\seeders\DatabaseSeeder.php

<?php
namespace Database\Seeders;
// use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
class DatabaseSeeder extends Seeder
{
  /**
   * Seed the application's database.
   */
  public function run(): void
  {
    // call others seeder class
    $this->call([
      PermissionTableSeeder::class,
      CreateAdminUserSeeder::class,
    ]);
  }
}

C:\xampp82\htdocs\testfr\database\seeders\PermissionTableSeeder.php

<?php
namespace Database\Seeders;
use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use Spatie\Permission\Models\Permission;
class PermissionTableSeeder extends Seeder
{
  /**
   * Run the database seeds.
   */
  public function run(): void
  {
    $permissions = [
      'role-list',
      'role-create',
      'role-edit',
      'role-delete',
      'product-list',
      'product-create',
      'product-edit',
      'product-delete',
      'user-list',
      'user-create',
      'user-edit',
      'user-delete',
    ];
    foreach ($permissions as $permission) {
      Permission::create(['name' => $permission]);
    }
  }
}

C:\xampp82\htdocs\testfr\database\seeders\CreateAdminUserSeeder.php

<?php
namespace Database\Seeders;
use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use App\Models\User;
use Spatie\Permission\Models\Role;
use Spatie\Permission\Models\Permission;
class CreateAdminUserSeeder extends Seeder
{
  /**
   * Run the database seeds.
   */
  public function run(): void
  {
    $user = User::create([
      'name' => 'Noor E Alam',
      'email' => 'admin@email.com',
      'password' => bcrypt('123456')
    ]);
    $role = Role::create(['name' => 'Admin']);
    $permissions = Permission::pluck('id', 'id')->all();
    $role->syncPermissions($permissions);
    $user->assignRole([$role->id]);
  }
}

Sử dụng morphs thiết kế database :)

<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration
{
  /**
   * Run the migrations.
   *
   * @return void
   */
  public function up()
  {
    Schema::create('taggables', function (Blueprint $table) {
      $table->integer('tag_id');
      $table->morphs('taggable');
    });
  }
  /**
   * Reverse the migrations.
   *
   * @return void
   */
  public function down()
  {
    Schema::dropIfExists('taggables');
  }
};

Một ví dụ sử dụng faker trực tiếp rất hay

C:\xampp\htdocs\datvietcoconut\database\seeders\DatabaseSeeder.php

<?php
use Illuminate\Database\Seeder;
// Import DB and Faker services
use Illuminate\Support\Facades\DB;
use Faker\Factory as Faker;
class DatabaseSeeder extends Seeder
{
  /**
   * Seed the application's database.
   *
   * @return void
   */
  public function run()
  {
    $faker = Faker::create();
    foreach (range(1, 500) as $index) {
      DB::table('employees')->insert([
        'firstname' => $faker->firstname,
        'lastname' => $faker->lastname,
        'email' => $faker->email,
        'dob' => $faker->date($format = 'D-m-y', $max = '2010', $min = '1980')
      ]);
    }
  }
}

C:\xampp\htdocs\datvietcoconut\database\migrations\2022_12_09_185509_create_employees_table.php

<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateEmployeesTable extends Migration
{
  /**
   * Run the migrations.
   *
   * @return void
   */
  public function up()
  {
    Schema::create('employees', function (Blueprint $table) {
      $table->id();
      $table->string('firstname');
      $table->string('lastname');
      $table->string('email')->unique();
      $table->string('dob');
    });
  }
  /**
   * Reverse the migrations.
   *
   * @return void
   */
  public function down()
  {
    Schema::dropIfExists('employees');
  }
}

C:\xampp\htdocs\datvietcoconut\routes\web.php

Route::get('/convert-to-json', function () {
  return Employee::paginate(5);
});

Laravel Factory: Manual Increment of Column, Number

class AliasCommandFactory extends Factory {

    private static $order = 1;

    protected $model = AliasCommand::class;

    public function definition() {
         $faker = $this->faker;
         return [
            'user_id' => User::inRandomOrder()->first()->id,
            'command' => $faker->word,
            'content' => $faker->sentence,
            'order'   => self::$order++
        ];
    }
}

Laravel 5.5 set size of integer fields in migration file

$table->increments('id')->length(11);
$table->dateTime('created_time');
$table->integer('bank_id')->length(11);
$table->tinyInteger('is_black')->length(1);

Length firstName 😒

'permission_id' => $this->faker->numberBetween(1, 30),
'permission_name' => $this->faker->firstName(10),
'created_at' => $this->faker->dateTime(),
'create_user' => $this->faker->firstName(10),
'deleted_at' =>$this->faker->dateTime(),
'delete_user' => $this->faker->firstName(10)

Chú ý cách dùng: migration

$faker = Faker\Factory::create();

$faker->name; // First and second name
$faker->randomDigit; // A random number
$faker->word; // A single word
$faker->sentence; // A sentence
$faker->unique()->word; // A single unique word
$faker->text($maxNbChars = 300); // 300 character long text
$faker->safeEmail; // An email address
$faker->hexcolor; // Hex color

Dùng giá trị mặc định cho cột, default, enum

C:\xampp\htdocs\reset\database\migrations\2022_05_20_184747_create_products_table.php

<?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');
      $table->enum('status', ['Pending', 'Wait', 'Active'])->default('Pending');
      $table->timestamps();
    });
  }
  /**

  public function down() {
    Schema::dropIfExists('products');

Laravel 8 pagination Example with Bootstrap 4

June 24, 2021Laravel Home » Laravel » Laravel 8 pagination Example with Bootstrap 4

Hey guys, in this tutorial I am going to cover how you can create the pagination in laravel 8 with the example of bootstrap 4. This is a step-by-step guide on laravel pagination example with Bootstrap 4 which is easy to follow. In this article, we are using articles as the example case and will paginate the articles. We will start off with setting up the laravel, then updating the DB credentials, creating model, migration and controller, connecting route with controller and creating the view, getting data from database and using paginate and links to create the pagination. So let’s get started.

Step 1: Install Laravel

First of all, you need to install the laravel. I am installing the laravel in pagination folder.

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

Step 2: Update the ENV file and start server

In this step, you need to update the DB credentials in the env file and start the server by typing:

php artisan serve

Step 3: Create Article model and migration

Now we will create the article model and its migration. For migration, we are using -m flag.

php artisan make:model article -m

Step 4: Update the migrate function and run migration

We will add the title and description in the article migration up function in database/migrations/create_articles_table.php.

Schema::create('articles', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->string('description');
            $table->timestamps();
        });

Now we need to migrate the table we created.

php artisan migrate

Step 5: Add the fake article data

You can skip this step if will add the data manually in the table. To add the dummy data we are using the seeders, so open up the seeders/DatabaseSeeder.php and update the run function to have the following code:

$faker= Faker::create();

        foreach (range(1,100) as $index){
            Article::create([
                'title'=>$faker->sentence(6),
                'description'=>$faker->paragraph(1),
            ]);
        }

We are using Faker to add the dummy title and description in the Article Table. 'title'=>$faker->sentence(6) will add the 6 words as the title and 'description'=>$faker->paragraph(1) will add 1 sentence as the description. We are adding 100 articles by doing that. Make sure to include the use App\Models\Article; and use Faker\Factory as Faker; in the header as well. To generate the data run command:

php artisan db:seed

Step 6: Create Controller and Route

Run the following command to create ArticleController.

php artisan make:controller ArticleController

Place the following code in the ArticleController.

<?php

namespace App\Http\Controllers;

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

class ArticleController extends Controller
{
    //
    public function get_data(){
        $articles = Article::all();
        return view('home', compact('articles'));
    }

}

Now lets create the route in routes/web.php file.

Route::get('get_data',[\App\Http\Controllers\ArticleController::class,'get_data']);

Step 7: Create View

Now create a blade file resources/views/home.blade.php and place the following code:

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>

    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css">
</head>
<body>

<div class="container mt-5">

    <h1 class="text-center">All the Articles</h1>

    <div class="row mt-5">
        @foreach($articles as $each_article)
            <div class="col-lg-4">
                <div class="card mt-2">
                    <div class="card-body">
                        <h5 class="card-title">{{$each_article->title}}</h5>
                        <p class="card-text">{{$each_article->description}}</p>
                    </div>
                </div>
            </div>
        @endforeach
    </div>
</div>

</body>
</html>

In this above home blade template, we have included the bootstrap and have used the card components to create the layout to show all the articles by traversing the $articles variable which we have passed from the ArticleController. If you open the browser and type get_data with the url on which your application is running you will see something like this.

So at this point the articles are loading without any pagination. Lets convert it so that it will load with pagination.

Step 8: Add the paginate in Controller

So in order to show articles with pagination we need to replace Article::all(); to Article::paginate(10); in ArticleController. So our final controller code will look like:

<?php

namespace App\Http\Controllers;

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

class ArticleController extends Controller
{
    //
    public function get_data(){
        $articles = Article::paginate(10);
        return view('home', compact('articles'));
    }

}

Where 10 is number of articles we want to display per page. You can change this number as you like. For now I am sticking to 10 articles per page.

Now if you refresh the browser page you will see that only 10 articles are loading but there is no pagination. So next step is we need to add the links in the home.blade.php file as well.

Step 9: Add the pagination links in the view file

So in the resources/views/home.blade.php, after the row div, we need to add {!! $articles->links() !!}.

So our final view file will look like this:

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>

    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css">
</head>
<body>

<div class="container mt-5">

    <h1 class="text-center">All the Articles</h1>

    <div class="row mt-5">
        @foreach($articles as $each_article)
            <div class="col-lg-4">
                <div class="card mt-2">
                    <div class="card-body">
                        <h5 class="card-title">{{$each_article->title}}</h5>
                        <p class="card-text">{{$each_article->description}}</p>
                    </div>
                </div>
            </div>
        @endforeach
    </div>

    {!! $articles->links() !!}
</div>

</body>
</html>

So the final result will look like this:

As you can see that the pagination links but its not looking good. As there is no CSS for the pagination. You can either write custom css for that or you can use the bootstrap pagination. In order to use the bootstrap pagination, we need to add the Paginator::useBootstrap(); in boot() function in app/Providers/AppServiceProvider.php .

So your AppServiceProvider file will look like this:

<?php

namespace App\Providers;

use Illuminate\Pagination\Paginator;
use Illuminate\Support\ServiceProvider;

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

    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        //
        Paginator::useBootstrap();
    }
}

And if you refresh the page, it will look like this:

Okay we are finally here just add the following CSS style in the head of the home.blade.php file.

<style>
        .pagination{
            float: right;
            margin-top: 10px;
        }
</style>

So the final home.blade.php will look like this:

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>

    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css">

    <style>
        .pagination{
            float: right;
            margin-top: 10px;
        }
    </style>
</head>
<body>
<div class="container mt-5">

    <h1 class="text-center">All the Articles</h1>

    <div class="row mt-5">
        @foreach($articles as $each_article)
            <div class="col-lg-4">
                <div class="card mt-2">
                    <div class="card-body">
                        <h5 class="card-title">{{$each_article->title}}</h5>
                        <p class="card-text">{{$each_article->description}}</p>
                    </div>
                </div>
            </div>
        @endforeach
    </div>

    {!! $articles->links() !!}
</div>

</body>
</html>

And if you refresh the browser it will look like this:
