module ActionCable module Helpers module ActionCableHelper # Returns an "action-cable-url" meta tag with the value of the url specified in your # configuration. Ensure this is above your javascript tag: # # # <%= action_cable_meta_tag %> # <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %> # # # This is then used by ActionCable to determine the url of your websocket server. # Your CoffeeScript can then connect to the server without needing to specify the # url directly: # # #= require cable # @App = {} # App.cable = Cable.createConsumer() # # Make sure to specify the correct server location in each of your environments # config file: # # config.action_cable.url = "ws://example.com:28080" def action_cable_meta_tag tag "meta", name: "action-cable-url", content: Rails.application.config.action_cable.url end end end end
