Just copy the code for flash messages from layouts/application.html.erb to the desired view file (the one rendered without layout) – Jagdeep Singh Jan 05 '18 at 09:27

You can use that in two ways
One You can use that inside page, which working without layout like
On the top of the page and every page which you need show flash
# page.html.erb
<% flash.each do |msg| %>
<%= msg %>
<% end %>
OR
<% if alert.present? %> # or :notice
<%= alert %>
<% end %>
Two This way is more generic like you can create a folder inside view and named common inside this create partial file and named _flash.html.erb
# view/common/_flash.html.erb
<% flash.each do |msg| %>
<%= msg %>
<% end %>
OR
<% if alert.present? %> # or :notice
<%= alert %>
<% end %>
and finally, you can render this on your file which needs to show the message like
On the top of the page and every page which you need show flash
<%= render partial: "common/flash" %>
Hope to help
