Recorder

Recorder tracks changes of your Rails models

Add this line to your application's Gemfile:

gem 'recorder'

And then execute:

$ bundle

Or install it yourself as:

$ gem install recorder

To enable logging on a model you just need to include Recorder::Observer into the model and configure logging options for it:

class Post < ActiveRecord::Base
  include ::Recorder::Observer

  recorder only: %i[title tags],
    associations: {
      author: { only: %i[full_name] },
      category: { only: %i[name slug] }
    }
end

Recorder supports the following options:

• ignore: [array] - attributes that are ignored on logging;
• only: [array] - only these attributes are logged, other attributes are ingored;
• associations: {hash} (hash) - allows to set what associations will be logged alongside with the model. For each association you can also set ignore and only options;
• async: bool - a logging strategy (true - asynchronous, false - synchronous).

There are two strategies for logging: synchronous and asynchronous. When the synchronous strategy is used, a revision record is saved immediately after a model is saved, and the async strategy moves creating of revision records to Sidekiq.

To enable storing of such data as user_id and ip, you need to include Recorder::Rails::ControllerConcern to ApplicationController. Recorder uses request_store to safely store these data on a thread level.

  class ApplicationController < ActionController::Base
    include Recorder::Rails::ControllerConcern
    ...
  end

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. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
