GIGO (Garbage In, Garbage Out) For ActiveRecord

See the GIGO project for general information.

Add this line to your application's Gemfile:

gem 'gigo-activerecord'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gigo-activerecord

This gem allows you to use GIGO with ActiveRecord in a few convenient ways. First by easily declaring that a column should be loaded through GIGO. Assuming you have a Note model with a subject column.

class Note < ActiveRecord::Base
  gigo_column :subject
end

@note.subject # => "€20 – “Woohoo”"

GIGO extends your model in such a way that still allows you to define your own instance methods and super up through the attribute method stack.

class Note < ActiveRecord::Base
  gigo_column :subject
  def subject
    super.upcase
  end
end

@note.subject # => "€20 – “WOOHOO”"

If you want to extend all :string and :text columns, use the gigo_columns method. All string/text columns will be GIGO'ized. Any arguments passed to gigi_columns will be excluded.

class LegacyTable < ActiveRecord::Base
  gigo_columns
end

Sometimes your serialized attributes need GIGO before loading the YAML.

class Order < ActiveRecord::Base
  serialize :notes, gigo_coder_for(Hash)
end

GIGO is fully tested with ActiveRecord 4.2 - 5 and upward. If you detect a problem, open up a github issue or fork the repo and help out. After you fork or clone the repository, the following commands will get you up and running on the test suite.

$ bundle install
$ bundle exec appraisal install
$ bundle exec appraisal rake test

We use the appraisal gem from Thoughtbot to help us generate the individual Gemfiles for each ActiveSupport version and to run the tests locally against each generated Gemfile. The rake appraisal test command actually runs our test suite against all Rails versions in our Appraisal file. If you want to run the tests for a specific Rails version, use rake -T for a list. For example, the following command will run the tests for Rails 5 only.

$ bundle exec appraisal activerecord50 rake test
