Rails 4 Upgrade Notes

I recently completed our upgrade to Rails 4. Below are various notes and links that may help you if you are upgrading your application to Rails 4. YMMV.

Overview

There is a good Rails Guide on upgrading, with a specific section on upgrading from Rails 3.2 to Rails 4.0. First, a bit about our specific application and the technologies used, pre-Rails 4 upgrade:

• Rails 3.2.14
• Ruby 2.0.0-p247

    return '' if resource.errors.empty?

    messages = resource.errors.full_messages.map { |msg| content_tag(:li, msg) }.join
    sentence = I18n.t('errors.messages.not_saved',
      count: resource.errors.count,
      resource: resource.class.model_name.human.downcase)

function number_to_currency(number, options) {
  try {
    var options = options || {};
    var precision = options["precision"] || 2;
    var unit = options["unit"] || "\u20AC";
    var separator = precision > 0 ? options["separator"] || "." : "";
    var delimiter = options["delimiter"] || ",";
    var parts = parseFloat(number).toFixed(precision).split('.');

    return unit + number_with_delimiter(parts[0], delimiter) + separator + parts[1].toString();

# the admin password for all of the IE VMs is “Password1″ without the quotes, it's also used for the password hints

1) Install VirtuaBox on your mac

http://download.virtualbox.org/virtualbox/4.1.10/VirtualBox-4.1.10-76795-OSX.dmg

2) Decide which versions of Internet Explorer you want to download and install – each version of Internet Explorer is contained within a separate virtual machine that runs within VirtualBox. In other words, if you want to run Internet Explorer 7, 8, and 9, you will need to download three separate VM’s, which may take a while so keep that in mind. Select the text below and copy it:

# Install ALL versions of Internet Explorer: IE 7, IE 8, and IE 9 (for now this script will also pull down a IE 6 vm with windows xp)
