Rails check if yield :area is defined in content_for

Question

I want to do a conditional rendering at the layout level based on the actual template has defined content_for(:an__area), any idea how to get this done?

Answer 1

@content_for_whatever is deprecated. Use content_for? instead, like this:

<% if content_for?(:whatever) %>
  
<%= yield(:whatever) %>
<% end %>
