# devise_last_seen
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**.

## Installation
You know, add this line to your application's Gemfile:
```ruby
gem 'devise_last_seen'
```
And then execute:
$ bundle
## Usage
In your model, add `:lastseenable` module as such:
```rb
# 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
```
```rb
class AddLastSeenToUsers < ActiveRecord::Migration[6.1]
def change
add_column :users, :last_seen, :datetime
end
end
```
## Configuration
Besides the column requirement you don't need customizations, but if you want to...
```rb
# 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
```
