我有一个有工作的Rails应用程序（使用Active Job）。我使用resque和resque-scheduler宝石对后端进行排队。
我想通过Heroku上的Resque将Rails应用程序连接到Redis-to-go服务器，但在日志中会收到很多错误消息，如下所示：
2019-12-01T12:04:00.942767+00:00 app[worker.1]: resque-scheduler: [INFO] 2019-12-01T12:04:00+00:00: Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)

2019-12-01T12:04:02.990485+00:00 app[worker.1]: resque-scheduler: [INFO] 2019-12-01T12:04:02+00:00: Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)
2019-12-01T12:04:04.004590+00:00 app[worker.1]: resque-scheduler: [INFO] 2019-12-01T12:04:04+00:00: Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)
2019-12-01T12:04:05.012344+00:00 app[worker.1]: resque-scheduler: [INFO] 2019-12-01T12:04:05+00:00: Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)
一切都适用于开发和生产环境，但不适用于Heroku。我发现了很多问题，但有类似的问题，但是他们的解决方案对我没有帮助。
我在Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)方法中从redis gem收到一条错误消息establish_connection。但是，当我从Rails控制台中找出必要的值时，我知道可以。

此外，我了解resque和resque-scheduler宝石的设置在Heroku上重新启动我的应用程序后可以正常工作，但是由于某些原因，Resque连接到localhost:6379而不是Redis-to-go服务器。您有什么想法，为什么会这样？以及如何解决这个问题？
我在下面提供了有关设置，使用宝石等的必要信息。
