GreyscaleRails

This is a collection of handy tools to make your life developing against the Greyscale.io platform easy and delightful.

Add this line to your application's Gemfile:

gem 'greyscale_rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install greyscale_rails

There are a few things this gem provides

GreyscaleRecord is the default ORM for the Greyscale.io platform and there's some configuration that needs to happen, but it's somewhat verbose. To spare you the pain of reading all those docs, you can configure everything in a single yaml file: greyscale.yml

Here's what it looks like

development:
  driver: yaml
  data_root: db/fixtures
  live_reload: true

test:
  driver: yaml
  data_root: test/db/fixtures

# in progress. For now production should use yaml or your own API with drivers
production:
  driver: greyscale
  data_root: http://api.greyscale.io
  revision_root: http://revisions.greyscale.io
  app_id: <APP_ID>
  app_key: <APP_KEY>

Here's what all the fields are:

• driver: tells the application to load the proper data fetcher. The options are
  • yaml: will load yaml files from your local file system folder, specified by data_root
  • greyscale: will load data from a remote server that complies to the Greyscale.io API standard (in progress)
• data_root: the root path of the source from which you want to load your data
• revision_root: the root path of the source from which you load data previews
• live_reload: reloads the data from source on every page load. Not recommended in production.
• app_id: Your app's Greyscale.io API id
• app_key: Your app's Greyscale.io API key

This is a module that's loaded into Application Controller that detects a revision key in params[:revision], and automatically applies the patch for the duration of the call.

NOTE: it applies it to GreycaleRecord::Base's data store, so if you have more than one store that you are using, this may not work as well as you hope.
