This devise extension, will ensure that devise will update a flag/timestamp on the model whenever a user is set. With this kind of feature you could show in your views something like last seen 3 weeks ago or last seen 2 minutes ago.

You know, add this line to your application's Gemfile:

gem 'devise_last_seen'

And then execute:

$ bundle

In your model, add :lastseenable module as such:

# app/models/user.rb
class User < ApplicationRecord
  devise :database_authenticable, ..., :lastseenable
end

Generate a rails migration to add the column to your devise model:

bundle exec rails g migration add_last_seen_to_users last_seen:datetime

class AddLastSeenToUsers < ActiveRecord::Migration[6.1]
  def change
    add_column :users, :last_seen, :datetime
  end
end

Besides the column requirement you don't need customizations, but if you want to...

# config/initializers/devise.rb
Devise.setup do |config|
  ...
  # Interval (in seconds) to update the :last_seen_at_attribute attr
  # config.last_seen_at_interval = 5.minutes
  # Attribute who will be updated every time a user is set by the Warden's after_save callback
  # Remember to check if this column name is present on the devise model table.
  # config.last_seen_at_attribute = :last_seen
end

After checking out the repo, run bin/setup to install dependencies. Then, run bundle exec rspec to run the tests.
