Doorkeeper: Dookeeper and ActionCable

[ViTVetal]

Hello!
I know that I should use stackoverflow for this kind of questions. I asked question

Is it possible use Dookeeper and ActionCable?
Look like approach should be similar to this or this.

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

    def connect
      self.current_user = find_verified_user
    end

    protected

      def find_verified_user 
        #CODE RELATED TO DOORKEEPER ????

        if user 
          user
        else
          reject_unauthorized_connection
        end
      end
  end
end

How can I get user by access_token and scope? (I use only access_token and refresh_token)

use_doorkeeper do
    skip_controllers :authorizations, :applications, :authorized_applications
end

I think it would be great if you add ActionCable related example to wiki

Hi @ViTVetal . max on StackOverflow already answered you. You can store access token in cookies (don't sure it is secure way, but) and send it with ActionCable requests. And then you can find Resource Owner by Access Token that associated with requested token.

@nbulaj ok. Thank you!
I can send token as param during connection:
ws://localhost:3000/cable/?access-token=********
But how can I "find Resource Owner by Access Token that associated with requested token."? I didn't find how can I do this.

[nbulaj]

Something like this:

def access_token
  @access_token ||= Doorkeeper::AccessToken.by_token(params[:token])
  # or
  #
  # Doorkeeper::OAuth::Token.authenticate(
  #   request, # don't sure how it can be replaced in ActionCable
  #   *Doorkeeper.configuration.access_token_methods
  # )
end

def current_user
  @current_user ||= begin
    User.find_by(id: access_token.resource_owner_id) if access_token # no need to raise ActiveRecord::RecordNotFound
  end
end

@nbulaj Thank you!

Try it and tell me if it is OK for you :) Or describe another solution, we can add it to Wiki as you said

[ViTVetal]

@nbulaj Yes. It is ok for me.
Draft version https://stackoverflow.com/a/49819013/3194048 (I am new in Rails so you may refactor this code but I think idea should be same).

Thank you again. Nice gem.

Thanks! It is now described in Doorkeeper and ActionCable. We can close the issue?

[ViTVetal]

@nbulaj Yes
