we4tech / lazy_attribute.rb
Created December 30, 2013 08:39
Define attribute which value is loaded and stored lazily. Ie. You want to get some data from a 3rd party API call but instead of setting them explicitly you want to get those on demand. Here are few lines of code to get it workable.
module Concerns
module LazyAttribute
extend ActiveSupport::Concern
included do
class_attribute :lazy_attributes
end
module ClassMethods
def attr_lazy(name, &logic_impl)

An illustration how we can use ruby thread for accelerating our normal RAKE tasks. (intended for posting in a local Ruby developers group https://www.facebook.com/groups/rubydevs/)
namespace :somestuffs do
desc 'Importing some big stuff that requies lotta network stuff'
task :import
file, tasks = ENV['FILE'], Queue.new
# Parse out CSV file and retrieve each row and queue them up
# for further processing.
#
# Keeping it a thread allows us to let this process continue while other
# threads are not in RUNNING state.

Last active December 24, 2015 06:59
What if, we've more pictorial relationship syntax than syntactical sugar ?
class Message
include Mongoid::Document
include Mongoid::Timestamps
field :subject, type: String
field :content, type: String
belongs_to :replied_to, class_name: 'Message', inverse_of: :replies, touch: true
belongs_to :sender, class_name: 'User', inverse_of: :sent_messages
has_many :replies, class_name: 'Message', inverse_of: :replied_to

we4tech / exp_factory_method.rb
Created September 21, 2013 05:48
Instead of relying on 3rd party service, we could wrap them in bridge or expose through factory or facade
def handle_action_created(action)
if action.from.kind_of?(Source)
$redis.lpush(
"#{self.class.name}:#{self.id}",
[action.from.node.id, action.from.node.neo_id].join(":")
)
end
end
# Perhaps we could do
