Does devise have 'callback'?

Question

After a user log in, I want to manually log this event and increment a counter column in database.

Is there something like after_login in Devise? Just as ActiveRecord's before_save?

Answer 1

Devise uses Warden behind the scenes and Warden supplies you with a number of callbacks:

Have a look at the after_authentication callback. That's what you are looking for.

Code:

Warden::Manager.after_authentication do |user, auth, opts|
  # your code here.. 
end

You can simply create a new initializer file and put the code there. (Like /config/initializers/warden_callbacks.rb)
