Laravel-根据存储在数据库中的设置处理作业中的多个Eloquent Model DB连接

编程问答 2022-06-08

问题描述

我的多租户Laravel 7 / mysql应用程序中有两种模型，例如：

  • Company->使用默认的连接/中央数据库，并配置为默认方式。
  • CompanySettings->属于Company-使用默认的连接/中央数据库，配置默认的方式-还保存Company的特定数据库的连接凭据。
  • Category->属于Company-它存储在特定的数据库中，专门为每个公司创建。连接凭据存储在CompanySettings中。

现在，当我创建http请求时，我能够基于主机识别公司，并且在中间件中，我将辅助连接凭据设置为存储在CompanySettings中的凭据。

但是，我的某些请求触发了排队事件（发送通知），该事件将Models与辅助连接一起使用。由于已排队事件作为后台作业运行，没有中间件，因此第二连接未填充正确的连接数据。注意：我在事件/通知上附加了Company，因此我可以识别公司，但是在这种情况下为模型设置数据库连接的正确方法在哪里，以便不触发以下错误？

使用的堆栈：Laravel 7，Mysql db，数据库中的作业
