LegacyColumn

A gem that will print a message if a developer is trying to use a column that is from a legacy system but has to stay there.

gem 'legacy_column'

Just list the column names:

legacy_column :old_email, :old_phone_number

A custom message can be added:

legacy_column :old_email, :old_phone_number, message: 'Do not touch this!!!'

It will output something like this in rails logs:

Use of legacy column detected.
  User => old_email
  Do not touch this!!!
