in my app there are three controllers…  
login, clients and users.

main controller is “clients” controller

now  
i kept all controller code in clients controller  
def index  
@clients = Client.find(:all)  
respond\_to do |format|  
format.atom  
end  
end

and all index.atom.builder code in views/clients/  
require”feedtool”  
require”feedreader”  
require”feedupdate”

atom\_feed do |feed|  
feed.title(“My Atom Feed”)  
feed.updated((@clients.first.created\_at))

for post in @clients  
feed.entry(client) do |entry|  
entry.title(client.title)  
entry.content(client.body, :type =\> ‘html’)

entry.author do |author|  
author.name(“EMF”)  
end  
end  
end
