Rails: How to change the title of a page?

Question

What is the best way to create a custom title for pages in a Rails app without using a plug-in?

Answer 1

This simple approach sets a default title, but also let you override it whenever you please.

In app/views/layouts/application.html.erb:

<title><%= yield(:title) || 'my default title' %></title>

And to override that default, place this in any view you like

<% content_for :title, "some new title" %>

Answer 2

You can also set it in a before_filter in your controller.

# foo_controller.rb

class FooController < ApplicationController

  before_filter :set_title

  private

  def set_title
    @page_title = "Foo Page"
  end

end

# application.html.erb

<h1><%= page_title %></h1>

You can then set conditions in the set_title method to set a different titles for different actions in the controller. It's nice to be able to see all the relevant page titles within your controller.

Answer 3

In short, I can write this down as follow

<%content_for :page_title do %><%= t :page_title, "Name of Your Page" %> <% end %>
