如何编写条件来测试我在Rails中位于哪个页面？

Question

What I would like to do is to not show the headder in my rails app if the user is on the home page. Right now, the header is rendered in this line in application.html.erb:

<%= render('layouts/header') %>

What I'd like to do is put a conditional so that this doesn't get rendered if I'm on the home page. I think it should be something like:

<%= render('layouts/header') if not @homepage %>

where I set @homepage to true in the controller for the homepage. Does this approach make sense within the rails framework?

有几种方法可以做到这一点，最简单的方法可能是：

<%= render('layouts/header') unless params[:controller] == 'homepage' %>
