before_action - performing an action to prevent

class WebsocketController < WebsocketRails::BaseController

private

def authenticate?
unless current_user.token == message[:token]
current_redirect_to ‘home/index’
false # that here we need to do to stop the further execution?
end
end

end

class WorldsController < WebsocketController
before_action :authenticate?

def index
current_html_insert ‘worlds/index’
end

end

From the documentation: If you call render, head or redirect_to from a before_action, the filter chain will be halted, but I have a different situation:
current_redirect_to and current_html_insert - are methods of controlling the behavior of the client through websockets,
they do not call methods render, head or ***redirect_to.***Please tell me how can I fix this problem.

Render nothing (literally.)

class WebsocketController < WebsocketRails::BaseController
  private

  def authenticate?
    unless current_user.token == message[:token]
      current_redirect_to 'home/index'
      render :nothing => true, :status => 301
    end
  end
end

Thank you, this is what you need!
