Laravel 7 Elasticsearch integration from scratch with example

May 12, 2020 XpertPhp Comments 0 Comment

In this article, we will discuss how to integrate Elasticsearch from scratch with example in laravel 7.

Elasticsearch is a real-time distributed and multitenant-capable full-text search engine. it provides HTTP web interface and JSON documents.

Overview

Step 1: Install Elasticsearch

Step 2: Create Table using migration

Step 3: Install Package

Step 4: Add providers and aliases

Step 5: Create Route

Step 6: Create a Model and Controller

Step 7: Create Blade Files

Step 8: Run Our Laravel Application

Step 1: Install Elasticsearch

We are going to install Elasticsearch in our system, If you haven’t downloaded elastic search then you can follow here.

Step 2: Create Table using migration

Now, We need to create a migration. so we will below command using create the students table migration.

php artisan make:migration create_students_table --create=students

1	php artisan make:migration create_students_table --create=students

After complete migration. we need below changes in the database/migrations/create_students_table file.

<?php

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

class CreateStudentsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('students', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('first_name');
            $table->string('last_name');
            $table->text('address');
            $table->timestamps();
        });
    }

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

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class CreateStudentsTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('students', function (Blueprint $table) {

$table->bigIncrements('id');

$table->string('first_name');

$table->string('last_name');

$table->text('address');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('students');

}

Run the below command. after the changes above file.

php artisan migrate

1	php artisan migrate

Step 3: Install Package

Now, We will install “elasticquent/elasticquent” package. so first open the composer.json file and add the below line.

"elasticquent/elasticquent": "dev-master"

1	"elasticquent/elasticquent": "dev-master"

Step 5: Add providers and aliases

We will add below providers and aliases in the “config/app.php” file.

'providers' => [
	....
	Elasticquent\ElasticquentServiceProvider::class,
],
'aliases' => [
	....
	'Es' => Elasticquent\ElasticquentElasticsearchFacade::class,
]

'providers' => [

....

Elasticquent\ElasticquentServiceProvider::class,

'aliases' => [

....

'Es' => Elasticquent\ElasticquentElasticsearchFacade::class,

]

Now, We will generate a configuration file for elastic search using the following command.

php artisan vendor:publish --provider="Elasticquent\ElasticquentServiceProvider"

1	php artisan vendor:publish --provider="Elasticquent\ElasticquentServiceProvider"

Step 6: Create Route

Add the following route code in the “routes/web.php” file.

<?php
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', function () {
   // return view('welcome');	
});
Route::get('studentSearch', 'StudentController@index');
Route::post('studentSearchCreate', 'StudentController@create');
?>

<?php

|--------------------------------------------------------------------------

| Web Routes

|--------------------------------------------------------------------------

| Here is where you can register web routes for your application. These

| routes are loaded by the RouteServiceProvider within a group which

| contains the "web" middleware group. Now create something great!

Route::get('/', function () {

// return view('welcome');

});

Route::get('studentSearch', '[email protected]');

Route::post('studentSearchCreate', '[email protected]');

Step 7: Create a Model and Controller

Here below command help to create the controller and model.

php artisan make:controller StudentController
php artisan make:model Student

1 2	php artisan make:controller StudentController php artisan make:model Student

Student.php

<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Student extends Model
{
    //
	protected $fillable = [
        'first_name','last_name', 'address'
    ];
}
?>

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Student extends Model

{

protected $fillable = [

'first_name','last_name', 'address'

];

}

StudentController.php

<?php
namespace App\Http\Controllers;
use App\Student;
use Illuminate\Http\Request;
use Response;
class StudentController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index(Request $request)
    {
      if($request->has('search')){
        $students= Student::search($request->input('search'))->toArray();
      }
        return view('student-search',compact('students'));
    }
    /**
     * create student.
     *
     * @return \Illuminate\Http\Response
     */
    public function create(Request $request)
    {
      $this->validate($request, [
               'first_name' => 'required',
               'last_name' => 'required',
               'address' => 'required',
        ]);
        $student= Student::create($request->all());
        $student->addToIndex();
        return redirect()->back();
    }
}
?>

<?php

namespace App\Http\Controllers;

use App\Student;

use Illuminate\Http\Request;

use Response;

class StudentController extends Controller

{

/**

* Display a listing of the resource.

* @return \Illuminate\Http\Response

public function index(Request $request)

{

if($request->has('search')){

$students= Student::search($request->input('search'))->toArray();

}

return view('student-search',compact('students'));

}

/**

* create student.

* @return \Illuminate\Http\Response

public function create(Request $request)

{

$this->validate($request, [

'first_name' => 'required',

'last_name' => 'required',

'address' => 'required',

]);

$student= Student::create($request->all());

$student->addToIndex();

return redirect()->back();

}

Step 8: Create Blade Files

Finally, We will create student-search file in the “resources/views/” folder directory and paste the below code.

student-search.blade.php

@extends('layouts.app')
@section('content')
<div class="row">
    <div class="col-md-8 col-md-offset-2">
        <h1 class="text-primary" style="text-align: center;">Laravel 7 Elasticsearch integration from scratch with example</h1>
    </div>
</div>
<div class="container">
  <div class="panel panel-primary">
    <div class="panel-heading">
      <div class="row">

        </div><!-- /input-group -->

                <p>{{ $value['last_name'] }}</p>
                <p>{{ $value['address'] }}</p>
              @endforeach
            @endif
          </div>
          <div class="col-lg-6">
            <div class="panel panel-default">
              <div class="panel-heading">

              <div class="panel-body">
                @if (count($errors) > 0)
                <div class="alert alert-danger">

                  <ul>
                    @foreach ($errors->all() as $error)
                      <li>{{ $error }}</li>
                    @endforeach
                  </ul>
                </div>
              @endif
                {{ Form::open(array('url' => 'StudentSearchCreate','autocomplete'=>'off')) }}
                  <div class="row">

Step 9: Run Our Laravel Application
We can start the server and run this example using the below command.

php artisan serve

1	php artisan serve

Now we will run our example using the below Url in the browser.

http://127.0.0.1:8000/studentSearch

1	http://127.0.0.1:8000/studentSearch
