Simple Flash Message Displayer

Sometimes you don’t need fancy flash message handling in your Rails application. Here’s a little helper method for those occasions:

def display_flash do |level, message|
    content_tag("p", message, :class => "flash-#{level}")


Say you do the following somewhere:

flash[:info] = "Your pizza has been ordered." 
flash[:warn] = "Your pizza will unfortunately be cold."

The output of display_flash will be:

<p class="flash-info">Your pizza has been ordered.</p>
<p class="flash-warn">Your pizza will unfortunately be cold.</p>

Simple and easy, like it should be.
