Rails Devise Action Cable

Question

I\'m trying to get Action Cable working with Devise.

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

    identified_by :current_us         


        

Answer 1

Update your connection.rb with the following:

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.studentid
    end

    protected

    def find_verified_user # this checks whether a user is authenticated with devise
      if verified_user = env['warden'].user
        verified_user
      else
        reject_unauthorized_connection
      end
    end
  end
end

Answer 2

Try setting the cookie in a warden callback.

Add a file to `config/initializers/your_file.rb``

Add this to the file:

Warden::Manager.after_set_user do |user, auth, opts|
  scope = opts[:scope]
  auth.cookies.signed["#{scope}.id"] = user.id
  auth.cookies.signed["#{scope}.expires_at"] = 60.minutes.from_now
end

Warden::Manager.before_logout do |user, auth, opts|
  scope = opts[:scope]
  auth.cookies.signed["#{scope}.id"] = nil
  auth.cookies.signed["#{scope}.expires_at"] = nil
end

Or you could do something like this:

verified_user = env['warden'].user
