Installation

Add this line to your application's Gemfile:

gem 'safe_migrations'

And then execute:

$ bundle

Or install it yourself as:

$ gem install safe_migrations

Usage

TODO: Write usage instructions here

To mark a step in the migration as safe, despite using method that might otherwise be dangerous, wrap it in a safety_assured block, e.g.

class MySafeMigration < ActiveRecord::Migration
  def self.up
    safety_assured { remove_column :foo_table, :foo_column }
  end
end

To override the safety check from the command line, without modifying the migration code, set the FORCE environment variable. This is useful when running migrations in a development environment rather than on a production server.

bundle exec rake db:migrate FORCE=t
