Question

I wrote the following code to display the show.html.erb view with an alert flash message:

render action: 'show', alert: 'Please fix mistakes outlined in red'

However, the alert doesn’t appear. Notices appear though. I assume my render action: 'show' call above is wrong as I wrote that just by intuition. This is my html.erb code:

<%if notice%><p id="notice"><%= notice %></p><%end%>
<%if alert%><p id="alert"><%= alert %></p><%end%>

Answer 1

A more standard way of dealing with flashes is to write the following in your view layout

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

and write the following in your controller

flash[:alert] = 'Please fix mistakes outlined in red'
render 'show'
