Question

With this code I am supposed to make flashes with the key success different from the others by only showing the value and not the close_flash and flash_background as you can see. It doesn’t work, but what do I do wrong?

<% flash.each do |key, value| %>
  <% if key == "success" %>

    <div class="flash_<%= key %>"><%= value %></div>

  <% else %>

    <div class="flash_<%= key %>">
      <%= value %> <a href="#" class="close_flash">x</a>
    </div>
    <div class="flash_background"></div> 

  <% end %>

<% end %>

Answer 1

the flash uses symbols:

key == :success # true

In many cases, rails hashes are implemented with indifferent access. This would mean o[:a] == o[‘a’] (specifically, o[:a].object_id == o[‘a’].object_id).
