Devise + Switch User : How to avoid update in trackable devise columns for a switch user?

Detlef_R · May 3, 2014, 5:15am

I am using switch_user https://github.com/flyerhzm/switch_user rails
gem
to login as any other devise user from an admin account. When I use
switch_user for an account, the devise session updates all the devise
trackable attributes for that user such as:

t.integer “sign_in_count”,
t.datetime “current_sign_in_at”
t.datetime “last_sign_in_at”
t.string “current_sign_in_ip”
t.string “last_sign_in_ip”

which I don’t want to happen. These updates should happen only when an
end
user actually logs in and not for an admin account through switch_user.

How can I achieve this?

Thanks.

Regards,
Ankur

There is a way provided by devise gem to skip the Trackable fields
updates
for a specific request. Devise uses a condition as :

if record.respond_to?(:update_tracked_fields!) &&
warden.authenticated?(options[:scope]) &&
!warden.request.env[“devise.skip_trackable”]

Above condition can be found at

github.com

heartcombo/devise/blob/main/lib/devise/hooks/trackable.rb#L6


      
          # frozen_string_literal: true
          
          
# After each sign in, update sign in time, sign in count and sign in IP.
          # This is only triggered when the user is explicitly set (with set_user)
          # and on authentication. Retrieving the user from session (:fetch) does
          # not trigger it.
          Warden::Manager.after_set_user except: :fetch do |record, warden, options|
            if record.respond_to?(:update_tracked_fields!) && warden.authenticated?(options[:scope]) && !warden.request.env['devise.skip_trackable']
              record.update_tracked_fields!(warden.request)
            end
          end

In whichever request you want to skip the Trackable fields updates you
just
need to set an variable devise.skip_trackable from environment as :

prepend_before_filter { env[“devise.skip_trackable”] = true }

This will skip the updating of following columns:

sign_in_count
current_sign_in_at
last_sign_in_at
current_sign_in_ip
last_sign_in_ip
