README

Permits a grace period for substractive column changes, via Active Record migrations.

This was inspired by (read: entirely lifted) from Whitehall with a few modifications.

Installation

Add this line to your application’s Gemfile:

gem 'deprecated_columns'

And then execute:

$ bundle

Or install it yourself as:

$ gem install deprecated_columns

Usage

class User < ActiveRecord::Base
  deprecated_columns :name
end

For subtractive migrations to columns in your schema you’ll see a warning, unless you’ve specifically marked the column(s) using the deprecated_columns macro.
