Working With Rails

Display your notice inside an html element like this.

Then style the element with css how ever you like. #notice { font-weight: bold;
}

Sorry, I didn’t escape my code

<div id="notice"><%= flash[:notice] %></div>

Or use something like Stickies.

Can you actually put divs in the controller?

No, that’s View code. It’s largely frowned upon to put any view code in the controller. However, you will want to set the flash value in the controller.

I have to second Chris Barnes and recommend you use a CSS style to control the appearance of the tag.

i’m afraid flash[:notice] is already deprecated in rails latest version

Why should flash[:notice] be deprecated? flash is basically just a Hash where you can store any kind of data for exactly one request. It just so happens that most people always used flash[:notice], flash[:error] and what not … It could also be flash[:foo] or flash[:info_message].

@topic: Just like the others said – wrap any HTML object around your flash[:notice] (p, div, span or whatever) and style it accordingly using CSS. You could, of course, also do something like flash[:notice] = “Record saved!” in your controller – but obviously, that’s not good MVC there! ;)

Cheers

yes, my mistake what i mean is flash declared as instance variable already deprecated. Others can be referred here :http://www.rubyonrails.org/deprecation
:)

to clarify for anyone still confused, @flash[:whatever] is deprecated, flash[:whatever] works as expected

application.rhtml:

    <% flash.each do |type,content| %>   
      <%# special flashes we don't want to show:  %>
      <% next if [:foo, :bar, :search].include?(type) %>
      <%= content_tag(:div, content, :id => "flash_"+type.to_s) -%> <br/>                 
    <% end -%>

stylesheet.css:

#flash_error {
    border: 2px solid #8B0000;
    padding:10px;
    background-color:#CD5C5C;
    color:gold;
    font-weight:bold;
}

#flash_notice {
    border: 1px solid green;    
    padding:10px;    
    background-color:#3CB371;
    color:#FFFF00;
    font-weight:bold;
}

I agree with Chris and Marcin – but tend to take it further. I set up a shared template for flashes under shared/_flash.rhtml
Then you can add appropriate styling for each flash type – if there’s one present. Generally something along the lines of Marcin’s example thus:

<% [:error, :warning, :notice].each do |level|
    if flash[level] -%>
      <div class="flash <%= level.to_s -%>"><%= flash[level].join('\n') -%></div>
  <% end -%>
<% end -%>

Then add the following to your stylesheet:

 .flash {
   font-weight: bold;
   padding: 5px;
   margin-bottom: 5px;
 }
.error {
   background-color: #FAA;
   border: solid 2px red;
 }
 .warning {
   background-color: #FFA;
   border: solid 2px yellow;
 }
 .notice {
   background-color: #AFA;
   border: solid 2px green;
 }
