Clearance gem not displaying flash messages (Ruby on Rails 5.0.1)

Question

How do I display flash messages when using the clearance gem for user authentication?

I have this code set in my view/layouts/application.html.erb inside the body tags:

<% flash.each do |key, value| %>
  <div class="alert alert-<%= key %>"><%= value %></div>
<% end %>

I have checked the docs and wiki but couldn't find anything. When I create a user or login/logout there is no flash message displayed.

清除不会显示用于登录或注销的成功闪烁，因为这些操作的成功不被认为是值得关注且值得警惕的。
