在Laravel中动态更改数据库连接 [英] Change the Database Connection Dynamically in Laravel

问题描述

我有一个具有登录表和每个用户相应数据库设置的主数据库.登录时，我应该动态更改从表中获取的数据库设置. 我可以更改数据库连接，但是这种连接不会持久.

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,
...
]);

当他/她在应用程序中注册时，会为每个用户创建一个新数据库，因此我没有在config/database.php

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

推荐答案

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，每当需要查询其他数据库时，只需更改数据库连接即可.

Well you can use the default database for user login and have a new field for the database name. Then whenever you need to query a different database, you can just change your db connection.

类似这样的东西

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