Page title helper for I18n with to_s for :show!

helpers.rb

  def page_title()
    object_name = controller_name.singularize
    if controller.instance_variables.include?(('@' + object_name).to_sym)
      locals = {
        object_name.to_sym => controller.instance_variable_get('@' + object_name).to_s
      }
    else
      locals = {}
    end

    I18n.t([controller_name, action_name, 'title'].join('.'), locals)
  end



### meanwhile, in en.yml
en:
  foos:
    index:
      title: "showing foos"
    show:
      title: "check out this awesome %{foo}"
    edit:
      title: "editing %{foo}"

Translate with all the controller instance variables

def tv(key, opts)
locals_hash = controller.instance_variables.collect{|var|
unless var.to_s.match(/^@/) then
[var.to_s.match(/^@(._)/)[1].to_sym, controller.instance_variable_get(var).to_s] rescue nil
end
}.compact

I18n.t(key, Hash[locals_hash].merge(opts))
