devise: Warden Key Missing - Action Cable

I’ve got an up to date Rails 5 app running Devise, and Action Cable. I can authorize the connection just fine, that is not the problem. The issue is using current_user helper within a notification partial that’s pushed out using Action Cable. It’s causing an error because no middleware is exec in Action Cable.

TLDR;

model record contains an after action that creates a notification record
notifications are background jobs, thus they do NOT stem from a controller
current_user helper causing error of missing warden key when used in a partial broadcasted with action cable

This sums it up better than I can. Here’s the accompanying link: https://evilmartians.com/chronicles/new-feature-in-rails-5-render-views-outside-of-actions

I’ve tried a few work arounds and haven’t had much luck, and I’m definitely not in the mindset of monkey patching. Any thoughts?

I’m bumping this again after researching on Google how to fix this error, and coming across my own bug report from back in March. I realize you don’t get paid to maintain this gem but if you have any thoughts, I’d love to hear them.

I was facing the same problem, when I tried to use ApplicationController.render to render the partial view that I want to pass to the action cable.

I’ve got the solution from the article linked below, but this solution makes sign_in_count increase whenever rendering a partial view using ApplicationController.render_with_signed_in_user.

 def self.render_with_signed_in_user(user, *args)
   ActionController::Renderer::RACK_KEY_TRANSLATION['warden'] ||= 'warden'
   proxy = Warden::Proxy.new({}, Warden::Manager.new({})).tap{|i| i.set_user(user, scope: :user) }
   renderer = self.renderer.new('warden' => proxy)
   renderer.render(*args)
 end

Hi there,

I’m running a project that uses:

Ruby 2.3.0
Rails 5.0.1
Actioncable 5.0.6

We are using Action Cable, and for authentication using Devise and Warden, we have the following code in the app/channels/connection.rb file.

module ApplicationCable
  class Connection < ActionCable::Connection::Base
  identified_by :current_user

 def connect
    self.current_user = find_verified_user
    logger.add_tags 'ActionCable', current_user.email
  end

  protected

  def find_verified_user
    if verified_user == env['warden'].user
     verified_user
    else
      reject_unauthorized_connection
    end
  end
end

Hope it helps. Regards.

Actually, this is an issue that happens when you want to render a partial outside of your actions…Like in a job, and your partial uses devise helpers (current_user, user_signed_in? etc). This is similar to the following issue: https://github.com/plataformatec/devise/issues/4271
