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:
我有一部分只有当某些页面使用该布局时我才想在布局中显示。我为我的所有页面设置了@page_title，并认为我可以使用这样的东西：
<% 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?
但是，包含仅发生在标题为“登录”的页面上，而不是其他页面上。是|| Case开关上不允许这样的语句？是否有不同的方法在案例开关中设置OR语句？
Thanks!
谢谢！

This is what you want:
这就是你想要的：
<% case @page_title when "Log in", "Forgot Your Password", "Create a New Password" %><%= render :partial => "common/hello-world" -%><% end -%>

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.
使用，而不是||在什么时候分开比赛。有关Ruby语法的更多信息，请参见http://docs.huihoo.com/ruby/ruby-man-1.4/syntax.html#case。
