Question

I’m trying to adjust the standard application template in Rails to insert a class around the notice and alert messages, but I can’t seem to find an elegant way of doing it.

At present, I have the scaffold:

  <p class="notice"><%= notice %></p>
  <p class="alert"><%= alert %></p>

I want it to only show the surrounding tags if a notice or alert is present.

Answer 1

Use an if statement.

<% if notice %>
    <p class="notice"><%= notice %></p>
<% end %>
