Rails: How to change the title of a page?

Best practice is to use content_for.

First, add a couple of helper methods (ie. stick in app/helpers/application_helper.rb):

def page_title(separator = " – ")
  [content_for(:title), 'My Cool Site'].compact.join(separator)
end

def page_heading(title)
  content_for(:title){ title }
  content_tag(:h1, title)
end

Then in your layout view you can simply use:

<title><%= page_title %></title>

...and in the view itself:

<%= page_heading "Awesome" %>

This way has the advantage of allowing you to shuffle where you stick the h1 tag for your title, and keeps your controller nice and free of pesky @title variables.


Here's a simple option that I like to use

In your layout

<head>
  <title><%= @title %></title>
</head>

And at the top of your page template (first line)

<% @title="Home" %>

Because of the way the layout and page templates are parsed the @title="Home" is evaluated before the layout is rendered.


In your views do something like this:

<% content_for :title, "Title for specific page" %>
<!-- or -->
<h1><%= content_for(:title, "Title for specific page") %></h1>

The following goes in the layout file:

<head>
  <title><%= yield(:title) %></title>
  <!-- Additional header tags here -->
</head>
<body>
  <!-- If all pages contain a headline tag, it's preferable to put that in the layout file too -->
  <h1><%= yield(:title) %></h1>
</body>

It's also possible to encapsulate the content_for and yield(:title) statements in helper methods (as others have already suggested). However, in simple cases such as this one I like to put the necessary code directly into the specific views without custom helpers.
