Env ['warden'] doesn't work with Rails 5
I'm following this tutorial to create a chat function using websites. https://www.sitepoint.com/rails-and-actioncable-adding-advanced-features/
I am having a problem that env['warden'].user
nothing is reconfiguring even when Im connected to an application with a standard development form.
And if I use another method (which is now commented out) - it returns the wrong user
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 # this checks whether a user is authenticated with devise
verified_user = env['warden'].user
if verified_user
verified_user
else
reject_unauthorized_connection
end
end
# def find_verified_user
# user_id = request.headers['HTTP_AUTHORIZATION']
# if verified_user = User.find_by(user_id)
# verified_user
# else
# reject_unauthorized_connection
# end
# end
end
end

I found a solution from this article https://rubytutorial.io/actioncable-devise-authentication/
I'm not sure how this works, but it makes the deal. How does it help people with a similar problem.
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
verified_user = User.find_by(id: cookies.signed['user.id'])
if verified_user && cookies.signed['user.expires_at'] > Time.now
verified_user
else
reject_unauthorized_connection
end
end
end
end
And I also created a file / config / initializers / warden _hooks.rb
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
