Sniffed

Have you ever faced a code that, for whatever reason, does something like this?

dog = Dog.find(1)
# => <Dog:0x00000 id: 1, first_name: "Jujuba", last_name: "The Crazy">
ActiveRecord::Base.transaction do
  dog.update(first_name: 'Sif')
  dog.update(last_name: 'The Dog')
end

Depending on your logic, it may make sense. And one day, you suddenly wake up needing to use saved_changes, but then...:

dog.saved_changes
# => { 'last_name' => ['Doe', 'The Dog'] }

Yep, you've lost track of the first_name changes. Sad, isn't it? But wait! I have a solution

Sniffed is the tool you were asking for all along!!!

Add this line to your application's Gemfile:

gem 'sniffed'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install sniffed

Just add sniffed to the model you want to keep track of those changes and then starting using like:

dog.sniffed_changes # if you are a funny guy like me
# => { 'first_name' => ['Jujuba', 'Sif'], 'last_name' => ['The Crazy', 'The Dog'] }
dog.commited_changes # if you are all serious
# => { 'first_name' => ['Jujuba', 'Sif'], 'last_name' => ['The Crazy', 'The Dog'] }

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.
