ippeiukai / sequel_abstract_model.rb
Last active November 25, 2015 09:47
Monkey patch to Sequel (http://github.com/jeremyevans/sequel) that lets you cleanly create an abstract model.
require 'sequel/model'
module Sequel
class << self
# abstract model needs to avoid inherited callback
# (see https://groups.google.com/forum/#!msg/sequel-talk/OG5ti9JAJIE/p1iqO57cwqwJ)
# MyAbstractModel = Sequel.new_abstract_model do
# # ... your common stuff ...

2 + 2 = 5 in Ruby. (http://en.wikipedia.org/wiki/Two_plus_two_make_five)
module TwoPlusTwoIsFive
def self.included(base)
base.class_exec do
alias_method :plus_without_two_plus_two_is_five, :+
private :plus_without_two_plus_two_is_five
alias_method :+, :plus_with_two_plus_two_is_five
public :+
end

ippeiukai / faster_fixture_loading.rb
Last active December 18, 2015 09:59
A monkey patch that speeds up fixture loading of Rails 3.2. The speed up in my case was by five-fold (with ``time rake db:fixtures:load``), quite significant if you have a large set of fixtures and load them regularly.
# for Rails 3.2.12
# loads fixtures a lot faster
require 'active_record/fixtures'
class ActiveRecord::Fixtures
# based on activerecord-3.2.12/lib/active_record/fixtures.rb l.462
# modified lines are marked CHANGED
def self.create_fixtures(fixtures_directory, table_names, class_names = {})
table_names = [table_names].flatten.map { |n| n.to_s }
