Change the Database Connection Dynamically in Laravel

Question

I have the master database with login table and corresponding database settings for each user. On login I should dynamically change the db settings fetching from the table. I can change the db connection but this is not persisting.

Config::set("database.connections.mysql", [
'driver' => 'mysql',
"host" => $usr_host,
"database" => $usr_database,
"username" => $usr_username,
"password" => $usr_password,
...
]);

edit: New database is created for each user when he/she registers with the app and thus i dont have the database connection for each user defined in the config/database.php

Answer 1

这样，您可以在涉及数据库时设置新参数：

 \Config::set('database.connections.mysql.database', $schemaName);

记住PURGE要保留此设置

 DB::purge('mysql');

干杯!

Answer 2

那么您可以使用默认数据库进行用户登录，并为数据库名称添加一个新字段。然后，每当您需要查询不同的数据库时，您只需更改数据库连接即可。

像这样的东西

$someModel = new SomeModel;
$databaseName = "mysql2"; // Dynamically get this value from db
$someModel->setConnection($databaseName);
$something = $someModel->find(1);
