			If your partial is more like a full-fledged action, you can render it as a file:
			<source lang="ruby">
			<%= render :file => 'comments/new' %>
			</source>
			which renders <code>app/views/comments/new.html.erb</code>.

			<source lang="ruby">
			<%= render @article %>
			</source>
			Rails looks for a partial in <code>app/views/articles/_article.html.erb</code> and automatically assigns a local variable called article. It's a shortcut for
			<source lang="ruby">
			<%= render 'article', :article => @article %>
			</source>
			<source lang="ruby">
			<%= render @articles %>
			</source>
			equivalent to
			<source lang="ruby">
			<% @articles.each do \|object\| %>
			<%= render object %>
			<% end %>

			== Layouts ==
			* The default layout for the entire application is <code>app/views/layouts/application.html.erb</code>.
			* If controller-specific layouts are found, they are used instead.
			* You can use the layout directive at the class level in any controller (that is, not inside an action) to set the layout for the entire controller:
			<source lang="ruby">
			layout 'my_layout'
			</source>
			* You can include a layout for a specific action with an explicit call to render inside the action:
			<source lang="ruby">
			render :layout => 'my_layout'
			</source>
			* Sometimes, you want to render an action without a layout. In that case, you can pass false in place of the layout name:
			<source lang="ruby">
			render :layout => false
			</source>
