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 Action Cable 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.mount_path = "/cable123" # <%= action_cable_meta_tag %> would render: # => # # config.action_cable.url = "ws://actioncable.com" # <%= action_cable_meta_tag %> would render: # => # def action_cable_meta_tag tag "meta", name: "action-cable-url", content: ( ActionCable.server.config.url || ActionCable.server.config.mount_path || raise("No Action Cable URL configured -- please configure this at config.action_cable.url") ) end end end end
