nickhoffman / app--helpers--application_helper.rb

Created October 18, 2011 15:20

pjax is awesome, but causes code within #content_for not to be rendered. Here's a solution.

	module ApplicationHelper
	def content_for_or_pjax(name, &block)
	request.headers['X-PJAX'] ? capture(&block) : content_for(name, &block)
	end
	end

	RSpec::Core::RakeTask.new('spec:changed') do \|t\|
	changed_files = `git status -s \| grep '^ M spec/' \| grep '_spec.rb$'`.split "\n"

	changed_files.each {\|file\| file.sub! /\A M /, '' }

	puts
	puts "Found #{changed_files.count} changed spec file(s):"
	changed_files.each {\|file\| puts " #{file}"}
	puts
