Laravel 6 config()->get('database.connections.mysql

问题描述

在我的本地环境中，我使用多个租户和 Redis(需要身份验证).
为了服务这个项目，我正在使用 Valet.

In my local environment I am working with multiple tenants and Redis (Auth required).
To serve the project I am using Valet.

对于这种情况，我要解决这两个连接:

For this case I am addressing these two connections:

- basic_foo (is defined in my .env)
- tenant_foo (is the one to change to during a request)

直到现在我成功地改变了连接:

Until now I successfully changed the connections like so:

config()->set('database.connections.mysql', 
       array_merge(
        config()->get('database.connections.mysql') , 
        ['database' => 'tenant_foo']
    ); 

问题

但是，现在我发现查询构建器存在问题，保持或回退到基本连接.

Problem

However, now I am seeing an issue with the query builder, keeping or falling back to the basic connection.

运行时得到tenant_foo的预期连接结果(Redis相同)

I get the expected connection results of tenant_foo (same for Redis) when I run

dd(config()->get('database.connections.mysql'));

当我运行时，basic_foo 的结果是错误的但显然是活跃的

I get the wrong but apparently active results of basic_foo when I run

dd(DB::connection()); // returns IlluminateDatabaseMySqlConnection

所以总而言之，应用程序将返回这个 IlluminateDatabaseQueryException

So all in all the app will return this IlluminateDatabaseQueryException

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'basic_foo.table_bar' doesn't exist...

应该在哪里搜索

'tenant_foo.table_bar'

还没有解决问题的事情

• 重启Redis
• 重新安装Redis
• php 工匠配置:缓存
• php artisan 缓存:清除
• php artisan route:clear
• php artisan view:clear
• php artisan 优化
• 作曲家转储自动加载

像下面那样简单地将数据库名称更改为 tenant_foo 是不够的，因为配置数组保持与 basic_foo 相同.

Simply changing the database name to tenant_foo like below is not enough, as the config array remains the same of basic_foo.

DB::connection()->setDatabaseName('tenant_foo');

想法

• 我想更改 DB::connection() 的配置数组，但我不知道除了 config->set() 之外的其他方法.
• 我安装了 Telescope 这会影响数据库连接吗?
• 还有其他想法吗?

Thoughts

• I want to change the config-array the of DB::connection(), but I don't know another way than the config->set().
• I installed Telescope could this affect the db connection?
• Any other ideas?

推荐答案

要动态更改数据库名称，您应该使用:

To dynamically change database name you should use:

DB::disconnect(); 
Config::set('database.mysql.database', 'tenant_foo'); 
DB::reconnect();
