2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.


What is Relay?


Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).
  

## embedded_many.rb
child_coll = Mongoid.default_session[:children]

Parent.all.each do |p|
  p.childs.all.each do |c|
    c.attributes['parent_id'] = p.id

    child_coll.insert c.attributes # save children to separate collection
  end

  p.childs = nil # remove embedded data

## active_model_serializer.rb
class LoLSerializer < ActiveModel::Serializer
...
hash["super_trooper"] = options[:super_trooper]
...
end
..

#Usage:
ActiveModel::ArraySerializer.new(ololol_collection,
  each_serializer: LoLSerializer, super_trooper: params[:super_trooper]).to_json

## overlaping_date.rb
class Interval < ActiveRecord::Base

  validates_presence_of :start_date, :end_date

  # Check if a given interval overlaps this interval
  def overlaps?(other)
    (start_date - other.end_date) * (other.start_date - end_date) >= 0
  end

  # Return a scope for all interval overlapping the given interval, including the given interval itself

## factories.rb
Factory.define :item do |f|
  include ActionDispatch::TestProcess

  f.name "Macbook Pro 15"
  f.price_in_dollars 1500
  f.photo fixture_file_upload('/files/avatar.jpg', 'image/jpg')
end

## symbolic_link.sh
ln -s /home/Data1 /home/Stores/abc
ln -f -s /home/Data2 /home/Stores/abc

## state_machine_names.rb
def available_types
  ClassName.state_machines[:message_type].states.map &:name
end
