Cannot use Neo4j with Laravel with the help of NeoEloquent

Question

I am trying to use Neo4j database in a Laravel project using NeoEloquent driver. I followed the instructions there. The config/database.php file has:

'default' => 'neo4j',

    'connections' => [

        'neo4j' => [
        'driver' => 'neo4j',
        'host'   => 'localhost',
        'port'   => 7687,
        'username' => 'neo4j',
        'password' => 'neo4j',
    ],
      .........
]

In web.php, I have:

Route::get('/save/country', [CountryController::class,'store'])->name('save_country');

Country.php model file has:

namespace App\Models;

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

// class Country extends Model
class Country extends NeoEloquent 
{
    use HasFactory;

    protected $fillable = [
      'country'
    ];


   
}

In CountryController.php, I have -

public function store(StoreCountryRequest $request) {

$country_info = new Country();
$country_info->country='India';
$relation = $country_info->save();

echo 'Success';

}

When I hit the URL save/country, I get the Exception:

RuntimeException Cannot connect to any server on alias: default with Uris: ('bolt://localhost:7687')

What is the thing that I am doing wrong ? How to make the problem go away ?

EDIT: I am using Neo4j Desktop app from here.

Is your database running? Are you able to connect from outside Laravel? — apokryfos, Jul 02 '23 at 12:10
@apokryfos, I have a created a Project named `tweety` in neo4j desktop app. Under it, I have tweetyDBMS. Then under it , I have neo4j and tweetdb. I clicked on the tweetyDBMS to start it. That's all. — Istiaque Ahmed, Jul 02 '23 at 12:27

You can use post and put to store and update data, get is only used when you pull data from a database.

Update your code Route::get('/save/country', [CountryController::class,'store'])->name('save_country');

to store Route::post('/save/country', [CountryController::class,'store'])->name('save_country'); and to update Route::put('/update/country', [CountryController::class,'update'])->name('update_country');

Regarding the Neo4j driver exception, though I am not an expert in Neo4j, you can check and try the following things:

What is your development environment?
Check if port 7687 is open and available or not.
If you are using or installing multiple Apache servers for development, then close or shut down the other Apache server.
