field_serializer

FieldSerializer

Ruby module which allows you to specify a set of fields that you'd like serialized in the #to_h method. We (EveryPolitician) are using this library in our scrapers to make them more declarative. It allows us to specify which fields we'd like to be scraped from a page without coupling ourselves to how the page is fetched or where the data ends up being stored.

Installation

Add this line to your application's Gemfile:

gem 'field_serializer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install field_serializer

Usage

require 'field_serializer'

class Person
  include FieldSerializer

  field :name do
    'Alice'
  end

  field :fruit do
    :apple
  end
end

puts Person.new.to_h
# => { :name => "Alice", :fruit => :apple }

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
