I have a partial that I want to display in a layout only when certain pages use that layout. I've set @page_title for all my pages and thought I could use something like this:
<% case @page_title when "Log in" || "Forgot Your Password" || "Create a New Password" %><%= render :partial => "common/hello-world" -%><% end -%>
But, the include is only happening on the page titled "Log in" and not the other pages. Are || statements like this not allowed on Case switches? Is there a different way to set an OR statement in the case switch?
Thanks!
This is what you want:
<% case @page_title when "Log in", "Forgot Your Password", "Create a New Password" %><%= render :partial => "common/hello-world" -%><% end -%>
Per http://docs.huihoo.com/ruby/ruby-man-1.4/syntax.html#case
Use , instead of || to separate the matches after when. See more about Ruby syntax in http://docs.huihoo.com/ruby/ruby-man-1.4/syntax.html#case.
