Simple Rewriter

As usually staging and production databases are different from each other, so testing new features on staging database can be painful because of lack of data, and diferrences of data.

Simple Rewriter enables ability to anonymize whole database with simply mappings, you can use dump production data to have production-like data on staging database without worrying about personal data.

Instalation

gem install simple_rewriter

Or in gemfile

gem "simple_rewriter", "~> 0.0.2"

Sample usage:

SimpleRewriter.call(
  record: user, 
  attributes: [
    :created_at, 
    { token: :hex },
    { email_field: :email },
    { address_field: :address },
    { hash_field: [:deep, :detect_type] },
    { remote_file_urls: { sample_pdf: true, default: [] }, # carrierwave support
    { hash: [
        :deep,
        {
          deep_attributes_map: [
            { zip: :zip },
            { street: :street },
            { name: [:first_name, :last_name] }
          ]
        }
      ] 
    }
  ]
)

Options	Expected Output
:email	eac94f-example@domain.com
:address	{:street=>"137 Fahey Street", :city=>"New Terryville", :zip=>"30752"}
:hex	6fe6a2485164f0
:name	Evie Upton
:first_name	Evie
:last_name	Upton
:phonenumber	333-333-3333
:zip	58517
:street	282 Kevin Brook
:city	Imogeneborough
:date	1972-01-02 01:23:21 +0100
:sample_pdf	http://www.africau.edu/images/default/sample.pdf
:deep	nil Only used to trigger rewriter to go deeper into record
:deep_attributes_map	nil Used to map deeper attributes of record

Options can be joined for e.g. passing [:first_name, :last_name] will give the same as [:name]

Configuration

Prevent rewriter from saving record

SimpleRewriter.configure do |config|
  config.save = false
end

Custom seeds

SimpleRewriter.configure do |config|
  config.integer_range = 0..10
  config.hash_key_length = 5
  config.rand_num_max = 10
  config.address = nil # override default address generator as hash with values
end

Custom readers/writers

SimpleRewriter.configure do |config|
  config.reader = SimpleRewriter::Reader
  config.writer = SimpleRewriter::Writer
end

Sample Pdf url

SimpleRewriter.configure do |config|
  config.sample_pdf_url = "http://www.africau.edu/images/default/sample.pdf"
end
