class ApplicationDecorator < Draper::Base

  # See +ApplicationDecorator.humanize+
  def humanize(attribute, key = model.send(attribute), default = key.to_s.humanize)
    self.class.humanize attribute, key, default
  end

  # By default, humanize the attributes listed.
  #
  # Contrived Example:

amiel

# Show a user-friendly version of our identifier
Status: <%= current_user.status.humanize %>

# Now we need to customize some of them, use I18n
Status: <%= t current_user.status, default: current_user.status.humanize %>

# But that's polluting our I18n namespace
Status: <%= t :"user.status.#{ current_user.status }", default: current_user.status.humanize %>

# Ok, this is getting out of hand, lets refactor this to the model

amiel

# Instead of this
after_create :advance_plan
def advance_plan
  plan.advance if plan

Avian hidden HTML Output Work Around

Open ~/Library/Application Support/TextMate/Session/Info.plist (the XCode plist editor makes it nice and easy, but you can open it in textmate as well if you are comfortable editing plists).

You are looking for htmlOutputHeight. Mine was set to a negative value, setting it to a positive value should fix the issue (it did for me).
