Additional real/virtual attribute change tracking independent of ActiveRecords

gem install delta_changes

class User < ActiveRecord::Base
  include DeltaChanges::Extension
  delta_changes columns: [:name], attributes: [:full_name]
end

user.name = "bar"
user.delta_changes # => {"name" => [nil, "bar"]}

user.full_name_will_change!
user.delta_changes # => {"name" => [nil, "bar"], "full_name" => [nil, "Mr. Bar"]}

user.save!
user.delta_changes # => {"name" => [nil, "bar"], "full_name" => [nil, "Mr. Bar"]}

user.reset_delta_changes!
user.delta_changes # => {}

To run tests: $ rake spec

To run tests with a specific Rails version listed in ./gemfiles, e.g. Rails 7.0:

$ BUNDLE_GEMFILE=gemfiles/rails7.0.gemfile rake spec

A new version is published to RubyGems.org every time a change to version.rb is pushed to the main branch. In short, follow these steps:

1. Update version.rb,
2. update version in all Gemfile.lock files,
3. merge this change into main, and
4. look at the action for output.

To create a pre-release from a non-main branch:

1. change the version in version.rb to something like 1.2.0.pre.1 or 2.0.0.beta.2,
2. push this change to your branch,
3. go to Actions → “Publish to RubyGems.org” on GitHub,
4. click the “Run workflow” button,
5. pick your branch from a dropdown.
