]
'aliases' => [
....
'DataTables' => Yajra\DataTables\Facades\DataTables::class,
]

Step 4 – Create Migration and Modal
In this step, execute the following command on the terminal to create post table migration and create Post Modal:
php artisan make:modal Post -m
database/migrations/2020_05_20_070104_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->integer('user_id');
$table->string('title');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('posts');
}
}
Now run the following command
php artisan migrate
After you have to update following code in your Post model file to create a posts table.
Next open Post.php model, which is placed inside App/models directory and create relationship in this model:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use App\Models\User;
class Post extends Model
{
use HasFactory;
protected $fillable = ['title'];
public function users()
{
return $this->belongsTo(User::class,'user_id','id');
}
}
Step 5 – Add route
Next, open your “routes/web.php” file and add the following route:
use App\Http\Controllers\PostController;
Route::get('posts', [PostController::class, 'index'])->name('posts.index');
Step 6 – Create Controller by Artisan Command
In this step, open your terminal execute the following command to create PostController.php file:
php artisan make:controller PostController
This command will create PostController by the artisan command.
Next, go to app/http/controller/PostController.php. and update the following methods into your controller file:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use App\Models\Post;
use DataTables;
class PostController extends Controller
{
/**
* Show the application dashboard.
*
* @return \Illuminate\Contracts\Support\Renderable
*/
public function index(Request $request)
{
if ($request->ajax()) {
$model = Post::with('users');
return DataTables::eloquent($model)
->addColumn('users', function (Post $post) {
return $post->users->name;
})
->toJson();
}
return view('users');
}
}
Step 7 – Create Blade File
In this step, Visit resources/views directory and create new file users.blade.php.
After that, update the following html and javascript code into your blade view file:
<!DOCTYPE html>

});
});
