Laravel: connect to databases dynamically

Closed 3 years ago.
I would like to get databases informations stored in my database and add it in the database.php.
I tried to get all infos in the database but I always have an error like this :
[2019-04-18 20:22:20] laravel.ERROR: Call to a member function
connection() on null {"exception":"[object]
(Symfony\Component\Debug\Exception\FatalThrowableError(code: 0):
Call to a member function connection() on null at
/var/www/vhosts/xxxx.net/httpdocs/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php:1249)
I added this on the top of database.php :
<?php
use App\Campaign;
$database_infos = Campaign::all();
$campains_db = array();
foreach ($database_infos as $info) {
if (isset($info->db_name)) {
$campains_db[$info->keyword] = array(
'driver' => 'mysql',
'host' => $info->db_host,
'database' => $info->db_name,
'username' => $info->db_user,
'password' => decrypt($info->db_password),
'prefix' => $info->db_prefix,
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'strict' => false,
'engine' => null,

}

I found this on an other post :
The simplest solution is to set your database config at runtime.
Laravel might expect these settings to be loaded from the
config/database.php file, but that doesn't mean you can't set or
change them later on.
The config loaded from config/database.php is stored as database in
Laravel config. Meaning, the connections array inside
config/database.php is stored at database.connections.
Config::set("database.connections.mysql", [
"host" => "...",
"database" => "...",
"username" => "...",
"password" => "..."
]);
