控制台中的 ActionCable.server.broadcast [英] ActionCable.server.broadcast from the console

问题描述

我可以在控制器中使用以下代码，但不能在控制台中使用(都是开发环境).我使用的是 Rails 5.0.0.beta2.

I can use the following code in the controller but not in the console (both development environment). I'm using Rails 5.0.0.beta2.

ActionCable.server.broadcast 'example_channel', message: '<p>Test</p>'

控制台:

>> ActionCable.server.broadcast 'example_channel', message: '<p>Test</p>'
[ActionCable] Broadcasting to example_channel: {:message=>"<p>Test</p>"}
=> []

如何在控制台中使用它?

How can I use it in the console?

推荐答案

ActionCable 在开发模式下的默认行为是使用 async 适配器，它仅在同一进程中运行.对于进程间广播，您需要切换到 redis 适配器.

The default behavior for ActionCable in development mode is to use the async adapter, which operates within the same process only. For inter-process broadcasting, you will need to switch to the redis adapter.

要在开发模式下启用redis，您需要编辑config/cable.yml:

To enable redis in development mode, you will need to edit config/cable.yml:

redis: &redis
  adapter: redis
  url: redis://localhost:6379/1

production: *redis
development: *redis
test: *redis
