BooleanTimestamps

Use boolean API's on your model, and persist the boolean as a timestamp when it was changed

Add this line to your application's Gemfile:

gem 'boolean_timestamps'

class Post < ActiveRecord::Base
  # assume published_at is in the schema
  boolean_timestamps :published_at
end

# use the boolean attribute to auto-update the timestamp attribute
post = Post.create!(published: true)
puts post.published_at
#=> 2015-10-17 08:27

# clear the timestamp with by setting the boolean to false
post.update!(published: false)
puts post.published_at
#=> nil

This also adds a scope for each timestamps column

Post.published
#=> [#<Post published_at: Fri, 04 Sep 2020 18:16:38 UTC +00:00>]

Post.published(false)
#=> [#<Post published_at: nil>]
