Step 2: Database Setup

In the second step, we will configure the database for the example database name, username, password, etc for our AJAX crud example of laravel. So open the .env file and fill in all details like as below:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database name(blog)
DB_USERNAME=database username(root)
DB_PASSWORD=database password(NULL)

Step 3: Add/Create Migration Table

We are creating an AJAX crud example for posts. So first, we have to create migration for the "posts" table using Laravel php artisan command, so the first type below command:

php artisan make:migration create_posts_table --create=posts

After running this command you will find php file here location "database/migrations/" in this file you need to add the below code.

<?php 

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

class CreatePostsTable extends Migration { 

/** 
* Run the migrations. 
* 
* @return void */ 

public function up() 
{ 
    Schema::create('posts', function (Blueprint $table) { 
            $table->bigIncrements('id');
            $table->string('title')->nullable();
            $table->longText('description')->nullable();
            $table->timestamps();
        });
    }

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

after this we need to run this migration by following command in our terminal:

php artisan migrate

Step 4: Add Resource Route

Now Add the Resource route in Routes/web.php

Route::resource('ajaxposts','PostAjaxController');

Step 5: Add Controller and Model

create the PostAjaxController using the following command.

php artisan make:controller PostAjaxController --resource --model=Post

Now make changes in Model, you will find a model in this path App/Post.php add the below code in post.php

<?php
  
namespace App;
  
use Illuminate\Database\Eloquent\Model;
   
class Post extends Model
{
    protected $fillable = [
        'id', 'title', 'description'
    ];
}

After changes in the model you will find PostAjaxController.php in this path app/Http/Controllers/PostAjaxController.php:

So, Copy code in your postajaxcontroller

<?php
         
namespace App\Http\Controllers;
          
use App\Post;
use Illuminate\Http\Request;
use DataTables;
        
class PostAjaxController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index(Request $request)
    {
   
        if ($request->ajax()) {
            $post = Post::latest()->get();
            return Datatables::of($data)
                    ->addIndexColumn()
                    ->addColumn('action', function($row){
   
                           $btn = '<a href="javascript:void(0)" data-toggle="tooltip"  data-id="'.$row->id.'" data-original-title="Edit" class="edit btn btn-primary btn-sm editPost">Edit</a>';
   
                           $btn = $btn.' <a href="javascript:void(0)" data-toggle="tooltip"  data-id="'.$row->id.'" data-original-title="Delete" class="btn btn-danger btn-sm deletePost">Delete</a>';
    
                            return $btn;
                    })
                    ->rawColumns(['action'])
                    ->make(true);
        }
      
        return view('postAjax',compact('post'));
    }
     
    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        Post::updateOrCreate(['id' => $request->id],
                ['title' => $request->title, 'description' => $request->description]);        
   
        return response()->json(['success'=>'Post saved successfully.']);
    }
    /**
     * Show the form for editing the specified resource.
     *
     * @param  \App\Post
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        $post = Post::find($id);
        return response()->json($post);
    }
  
    /**
     * Remove the specified resource from storage.
     *
     * @param  \App\Post
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        Post::find($id)->delete();
     
        return response()->json(['success'=>'Post deleted successfully.']);
    }
}

Now make changes in Model, you will find a model in this folder App/Post.php add the below code in post.php

<?php
  
namespace App;
  
use Illuminate\Database\Eloquent\Model;
   
class Post extends Model
{
    protected $fillable = [
        'id', 'title', 'description'
    ];
}
