ActsAsScrubbable

Scrubbing made easy

Acts as scrubbable give you model level access to scrub your data per object.

It runs using the parallel gem for faster processing which is dependent on the amount of cores available on the box. More cores == faster scrubbing

Installation

gem 'acts_as_scrubbable'

Usage

Simple add the configuration for your fields that map directly to your columns

class User < ActiveRecord::Base
  ...

  acts_as_scrubbable :first_name, :last_name


  # optionally you can add a scope to limit the rows to update
  scope :scrubbable_scope, -> { where(some_value: true) }

  ...
end

Incase the mapping is not straight forward

class Address
  acts_as_scrubbable :lng => :longitude, :lat => :latitude
end

To run

The confirmation message will be the db host

rake scrub

ActsAsScrubbable.configure do |c|
  c.add :email_with_prefix, -> { "prefix-#{Faker::Internet.email}" }

  c.after_hook do
    puts "Running after commit"
    ActiveRecord::Base.connection.execute("TRUNCATE some_table")
  end
end
