Question

I am trying to have one image show for the header on the root page of a RoR site, and all the other pages will randomly show one of three other picture. The problem is I don’t know how to get this to work. Any ideas?

Answer 1

In your application layout you can define the default header like this:

<% if content_for?(:header) %>
<%=yield(:header)%>
<% else %>
<%=image_tag(files[rand(files.length)])%>
<% end %>

And in the view for your home page, you would override it using content_for:

<% content_for :header do %>
<%=image_tag 'home.jpg' %>
<% end %>
