// description of your code here
In your controller add the name of the .rhtml file in /apps/layouts/ that you want to use, without the suffix (.rhtml).
When rails spits out your view, it will use this given layout as the container for your rendered action.

The solution—or at least a nice, cheap bandaid that can be applied easily, consists of adding a method to ActiveRecord::Base to help generate these ids without any brainpower involved.

Here’s a very simple implementation that I use in my projects, courtesy of Jamis Buck:

class ActiveRecord::Base
  def dom_id(prefix=nil)
    display_id = new_record? ? "new" : id
    prefix ||= self.class.name.underscore
    prefix != :bare ? "#{prefix.to_s.dasherize}-#{display_id}" : display_id
  end
endSo, you can do stuff like this in your views:

<ul>
<% @entries.each do |entry| %>
  
>
    <%= entry.body %>
  
<% end %>
And stuff like this in your controller:

def remove_entry
  entry = JournalEntry.find(params[:id])
  update_page do |page|
    page[entry.dom_id].remove
  end
end
