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

I am using 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.

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 https://github.com/plataformatec/devise/blob/master/lib/devise/hooks/trackable.rb#L6
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:

  1. sign_in_count
  2. current_sign_in_at
  3. last_sign_in_at
  4. current_sign_in_ip
  5. last_sign_in_ip
