Rails 3 - Ideal way to set title of pages

Question

Whats the proper way to set the page title in rails 3. Currently I\'m doing the following:

app/views/layouts/application.html:

Answer 1

I prefer this:

module ApplicationHelper
  def title(*page_title)
    if Array(page_title).size.zero?
      content_for?(:title) ? content_for(:title) : t(:site_name)
    else
      content_for :title, (Array(page_title) << t(:site_name)).join(' - ')
    end
  end
end

If title is called without arguments, it returns the current value of title or the default which in this example will be "Example".

It title is called with arguments, it sets it to the passed value.

# layouts/application.html.erb


# views/index.html.erb
<% title("Home") %>

# config/locales/en.yml
en:
  site_name: "Example"
