RailsAnonymizer

Anonymize your DB.

Usage

• Setup your blacklist in the initializer
• Restore your prod DB on a local environment with bin/rails db:anonymize:restore FILE=prod.dump
• Run bin/rails db:anonymize
• Dump your anonymized DB with bin/rails db:anonymize:dump (currently works only for postgresql, PR to support other DBs welcome)

Example of initializer

# config/initializers/rails_anonymizer.rb
begin
  ANONYMOUS_PASSWORD = User.new(password: "password").encrypted_password
rescue ActiveRecord::NoDatabaseError, ActiveRecord::StatementInvalid => e
end

RailsAnonymizer.setup do |config|
  config.before do
    # run some code before anonymizing
  end

  config.after do
    # run some code after anonymizing
  end

  config.black_list = {
    "email" => -> { Faker::Internet.unique.safe_email },
    "encrypted_password" => -> { ANONYMOUS_PASSWORD },
    "name" => ->(record) { "customer_#{record.id}" },
    "address" => -> { Faker::Address.full_address },
    "User" => {
      "phone_number" => -> { "+33333333333" },
    },
  }
end

Skip model

If you want to skip a model, add the class method skip_anonymizer? to the model and make it return true.

Installation

Add this line to your application's Gemfile:

gem 'rails_anonymizer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_anonymizer

Contributing

PRs welcome.
This gem depends on Rails, but we could imagine a version of it that only depends on ActiveRecord or even just read and write directly into the SQL file. Feel free to suggest a PR that does that.
