Laravel 5.6 change database connection in the runtime permanently - php

Question

I have two databases. The second database changes dynamically, i.e. each client has its own database so the database name and password are different but the architecture is the same for all clients. So I have two model groups, the first for the first database and the second for the second database. Indeed, the second model group must be able to make queries to the client database and not to the default database
so I want to set the default database connection dynamically.Config::Set() will do it for one request only. I want it for every subsequent request.
I use the Laravel Framework, you know of a clean solution that might solve my problem and help others interested
thanks to everyone for your help

Answer 1

Create two entries in config/database.php:
'connections' => array(
# Connection one
'mysql_1' => array(
'driver' => 'mysql_1',
'host' => 'host_1',
'database' => 'db_1',
'username' => 'username_1',
'password' => 'password_1'
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
# Connection two
'mysql_2' => array(
'driver' => 'mysql_2',
'host' => 'host_2',
'database' => 'db_2',
'username' => 'username_2',
'password' => 'password_2'
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
),
Create a base model or a Trait for each group of models which sets the connection at the model level. Change all your models to extends from their respective base model.
Base Models
class BaseGroupOneModel extends Model
{
protected $connection = 'mysql_1';
}
class BaseGroupTwoModel extends Model
{
protected $connection = 'mysql_2';
}
Traits
trait GroupOneTrait
{
protected $connection = 'mysql_1';
}
trait GroupTwoTrait
{
protected $connection = 'mysql_2';
}
class GroupOneModel extends Model
{
use app/Models/Traits/GroupOneTrait;
}
class GroupTwoModel extends Model
{
use app/Models/Traits/GroupTwoTrait;
}
