How to access session from Warden/Devise after_authentication callback in Rails

Question

I'm trying to access the current session from Warden's after_authenticate callback (running underneath Devise) in Rails 3.

At the top of my application controller I want to do something like:

Warden::Manager.after_authentication do |user,auth,opts|
  user.associate_with_ids(session[:pending_ids])
end

The ultimate goal is to take a list of record IDs that were stored in the session before sign up and associate them with the user model after sign in.

Any help would be much appreciated.

Answer 1

"auth.session" get/sets the data in the session key "warden.user.#{scope}.session".

Supposing you had saved pending_ids within your rails app:

session[:pending_ids] = ...

and you wanted to acces in the warden hook, you could access it this way:

Warden::Manager.after_authentication do |user,auth,opts|
  user.associate_with_ids(auth.env['rack.session'][:pending_ids])
end

It took me a while to find that out, so I guess it might be of some help for somebody.

You can access the session store via auth:

Warden::Manager.after_authentication do |user,auth,opts|
  user.associate_with_ids(auth.session[:pending_ids])
end

I found that auth.session did not work. It exists, but is not the same as session from the controller context. – Stemware

When i do that i get undefined local variable or method `session' for #<Class:0x007fa2cbfe6c60> – Carchemish

Answer 3

You can also access the session through auth.request.session.

So your example would be:

Warden::Manager.after_authentication do |user,auth,opts|
  user.associate_with_ids(auth.request.session[:pending_ids])
end

you can also find the whole session from the auth.raw_session
