the-undefined / minitest_vs_rspec_example

Created October 18, 2013 10:24

The main difference between Minitest and Rspec for ME is the conciseness of the assertion you can impose using Rspec.

	# Minitest
	it "should create a new credit card" do
	from_hash = CreditCard.create_from_hash(hash)
	assert from_hash.valid?
	assert from_hash.number == number
	assert from_hash.cvv == cvv
	assert from_hash.expiry_month == expiry_month
	assert from_hash.expiry_year == expiry_year
	end

the-undefined / n_plus_one_inserts.rb

Created September 2, 2013 20:22

Multiple record attribute hashes handed to an ActiveRecord model create method uses multiple SQL Insert statements, disappointingly.

	Item.create(name: 'one record, one query') # One SQL Insert Query

	multiple_items = [{ name: 'record one'}, { name: 'record two' }]
	Item.create(multiple_items) # Two Consecutive SQL Insert Queries

the-undefined / attr_capcessor.rb

Created August 20, 2013 20:54

Take advantage of metaprogramming and avoid littering the logic of your code with `define_method` declarations.

	module Cappy
	def attr_capcessor attr
	attr_reader attr.to_sym

	define_method "#{attr}=" do \|value\|
	instance_variable_set("@#{attr}", value.to_s.upcase)
	end
	end
	end

the-undefined / fetch_and_delete_stale_branches

Created August 12, 2013 10:52

When fetching in git use `-p` flag to delete stale local branches (when their tracking branches have been deleted on the remote repo).

	$ git fetch -p
	remote: Counting objects: 1, done.
	remote: Total 1 (delta 0), reused 1 (delta 0)
	Unpacking objects: 100% (1/1), done.
