You can include multiple javascript and css files with:


  <%= stylesheet_link_tag 'scaffold', 'master' %>
  <%= javascript_include_tag 'prototype', 'effects', 'controls', 'edit' %>

Alternating Row Colors without redundant classes:


#In a helper
 def alternate_class
     @class = (@class != '') ? '' : 'class="shade"'
 end

#In your view

Save values of a multiselect dropdown (ie. Articles belongs to many categories):


#In your controller
      @article.categories.clear
      @article.categories << Category.find(@params[:categories])
      if @article.save
        flash[:notice] = 'Article was successfully created.'
        redirect_to :action => 'show', :id => @article.id
      end

#In your view
<p>

Lets say you had a sidebar in your app, in each view the contents for this sidebar might change. Instead of putting the sidebar code inside every view you could do something like:


#In your _layout_ file
<div id="sidebar">
   @content_for_sidebar
</divp>

#In your view(s)
  <% content_for('sidebar') do %>
    <p>You are now on a really hip page!</p>
  <% end %>

Got any quick drops of goodness of your own?

UPDATE: Textpattern is doing weird stuff with my code, either way I code it whether escaping it or not it renders as html code on my live site or in RSS readers. Looking into that now.
