Question

我有一种情况需要让delayed_job在单独的数据库/表上使用自定义后端。

所以基本上强迫它使用单独的架构而不是我的应用主要使用的架构。

关于如何做到这一点的任何想法？提前谢谢。

Answer 1

你可以让你的一些模型连接到不同的数据库并使用不同的表。

在database.yml

中指定新数据库的配置

delayed_jobs_db_connection:
  adapter: mysql # or any other adapter
  database: delayed_jobs_db
  username: root
  password:
  host: localhost

在模型中，我们将使用establish_connection建立与此数据库的连接。您还可以直接在模型中指定所有配置，将其保留在配置中只是一种更好的方法。希望这会有所帮助。

我知道这个问题已经问了很久了，但是我也面临着同样的挑战，这种简单的方法对我有用：
