SmartIgnoredColumns

Now you won't forget to delete those ignored columns.

• ruby 3.2+
• activerecord 7.2+

Add this line to your application's Gemfile:

gem "smart_ignored_columns", group: [:development, :test]

1. Specify deadlines when ignoring columns:

class User < ApplicationRecord
  self.ignored_columns += [
    { name: "first_name", remove_after: "2025-08-24" } # date can be a String or a Date
  ]
end

2. Run a check on CI to warn when it is time to remove ignored columns:

bundle exec rake smart_ignored_columns:obsolete

If there are any obsolete ignored columns, the check will print them and exit with an error status code.

If you want to print all ignored columns with their deadlines, run:

bundle exec rake smart_ignored_columns:list

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 the created tag, and push the .gem file to rubygems.org.
