ContentGiven

Adds a very small helper to your views for determining if content_for :foo was used.

This means you don't always have to render the containing markup around yield :foo.

Example

Before content_given:

<!-- In app/views/layouts/application.html.erb %>
<html>
  <body>
    <div id="sidebar">
      <%= yield :sidebar
    </div>

    <div id="content">
      <%= yield %>
    </div>
  </body>
</html>

<div id="sidebar"> is always rendered.

After content_given:

<!-- In app/views/layouts/application.html.erb %>
<html>
  <body>
    <% if content_given? :sidebar %>
      <div id="sidebar">
        <%= yield :sidebar
      </div>
    <% end %>

    <div id="content">
      <%= yield %>
    </div>
  </body>
</html>

<div id="sidebar"> is only rendered if you used content_for :sidebar
