Data Integrity

Programming is hard. We must valiantly fight complexity on a daily basis. Conditional statements quickly increase the complexity of a system. Every time we’re unsure about a value, we add a conditions to decide how to proceed. If only we could become more confident with the state of the system…

Hurrah! Data integrity can give us this confidence. By constraining our data, we can make some assumptions about the state of the system. Gone are the days of guarding potentially nil values. Out with orphaned and duplicate records! Data is the [life] of our software. Let’s take [life] by the reigns.

MailChimp's default popup scripts can break on WordPress sites that use jQuery/jQuery UI unless you include their embed code as the final elements before the closing body tag.

Including them in this way isn't always possible or easy with WordPress.

The code below is an alternative implementation of the loader that forces MailChimp's popup scripts to appear below all other scripts upon page load.

To use it, modify the baseUrl, uuid, and lid attributes with the ones from the original popup script that MailChimp supplies.

	def select2_select(text, options)
	page.find("#s2id_#{options[:from]} a").click
	page.all("ul.select2-results li").each do \|e\|
	if e.text == text
	e.click
	return
	end
	end
	end

	# select2_ajax helper to make capybara work with ajax-enabled Select2 elements
	# assumes 'placeholder' option is used in Select2 (if it is using ajax, it should be)
	#
	# usage:
	#
	# it "should have a select2 field for searching by team name" do
	# @team = Factory :team
	# select2_ajax @team.name, :from => "Select a Team", :minlength => 4
	# click_button "Join"
	# page.should have_content "You are now on '#{@team.name}'."

	def merge(pdf_paths, destination)

	first_pdf_path = pdf_paths.delete_at(0)

	Prawn::Document.generate(destination, :template => first_pdf_path) do \|pdf\|

	pdf_paths.each do \|pdf_path\|
	pdf.go_to_page(pdf.page_count)
