How to use multiple databases in Laravel
(7 answers)
Closed 4 years ago.
I'm trying to make a laravel use using multiple databases:
Laravel version: 5.5.28
Php Version 7.2.0
Database Driver & version: MariaDB 10.1.29
Define Connections:
return array(
'default' => 'mysql',
'connections' => array(
# Primary/Default database connection
'mysql' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'bdd1',
'username' => 'root',
'password' => ''
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
# Secondary database connection
'mysql2' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'bdd2',
'username' => 'root',
'password' => ''
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
),
);
Define model:
class Products extends Model {
protected $connection = 'mysql';
}
Define controller:
class ProductController extends BaseController {
public function find()
{
$productModel= new Products;
$productModel->setConnection('mysql2');
$product= $productModel->find(1);
return $product;
}
}
The code above works without error, but if I change the name of the connection in the controller it continues using what was configured in the .env file
Please, could anyone help me solve this problem?

Answer 1

You can config:
In .env
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=bdd1
DB_USERNAME=root
DB_PASSWORD=
DB_CONNECTION_SECOND=mysql2
DB_HOST_SECOND=localhost
DB_PORT_SECOND=3306
DB_DATABASE_SECOND=bdd2
DB_USERNAME_SECOND=root
DB_PASSWORD_SECOND=
In config/database.php :
'mysql' => [
'driver' => env('DB_CONNECTION'),
'host' => env('DB_HOST'),
'port' => env('DB_PORT'),
'database' => env('DB_DATABASE'),
'username' => env('DB_USERNAME'),
'password' => env('DB_PASSWORD'),
],
'mysql2' => [
'driver' => env('DB_CONNECTION_SECOND'),
'host' => env('DB_HOST_SECOND'),
'port' => env('DB_PORT_SECOND'),
'database' => env('DB_DATABASE_SECOND'),
'username' => env('DB_USERNAME_SECOND'),
'password' => env('DB_PASSWORD_SECOND'),
],
Good luck !

There are two methods to achieve this, once you change the connection on the fly you have to propagate the connection which you can do like this.
if ($this->propogateConnection) {
$instance->setConnection($this->getConnectionName());
}
Another thing is you can use Model::on('connection_name',true) and true is for propagating the connection.
Hope this helps.
