This gem allows you to track any changes in your tables. This approach not only is suitable for model updates but also enables you to track dataset updates.

You should wrap your updating code as follows:

Model.with_current_user(current_user) do
  Model.where(...).update(...)
end

Method #with_current_user expects current_user to be an object (or record) having attributes id and login

You are able setup polymorphic associations between audit records and corresponding records.

Add this line to your application's Gemfile:

gem 'sequel-bulk-audit'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sequel-bulk-audit

After Installation you should run rails g audit_migration generator.

You can exdend this migration by attaching the trigger to audited tables.

Models, changes in which you plan to audit should contain

plugin :bulk_audit

Method #with_current_user should wrap all the operations on the table.

Model.with_current_user(current_user) do
  Model.where(...).update(...)
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.
