strange Devise / Warden hooks error / behavior

Question

I have implemented the code in Devise call backs in my application controller. First of all is this the right place?

I get both the

after_authentication 

and

after_set_user

to work. But I get this error for

before_logout

NoMethodError in Devise::SessionsController#destroy
undefined method `update_attribute' for nil:NilClass

The funny thing is that the database record is updated, dispite the error message. Strange.

Answer 1

This was a while back. When I implemented the after_authentication and before_logout I got multiple records, really strange.

To clarify I wanted to store ip etc on every session not just the last session.

I solved it by adding this in the config/initializers/devise.rb. Add code for what ever you want to store about the session.

Warden::Manager.after_authentication do |user,auth,opts|
  #store what ever you want on login
end

Warden::Manager.before_logout do |user,auth,opts|
  # store what ever you want on logout
  # If not in initializer it will generate two records (strange)
end
