You can move the customer info out of the invoices loop so it only displays once. So, instead of this:

<% for invoice in @customer.invoices %>
Invoice to:

<%= @customer.name %>
<%= @customer.address %>
<% end %>

Do this:

Invoices to:

<%= @customer.name %>
<%= @customer.address %>
<% for invoice in @customer.invoices %>
  ...
<% end %>

I'm pretty sure its a "less is more".

In your invoice controller if you do this..

  
def show
 @invoices = Invoice.find(:all)
end

you should be all set...(if your relationship stuff is connected..)

then in the view you show the invoices like this:

<% for invoice in @invoices %>
Invoice to:

<%= invoice.customer.name %>
<%= invoice.customer.address %>
<% end %>

because then each invoice is looped through 1 at a time, and you will be accessing specific information for each invoice
ie. invoice.customer.name

I guess its really simple like the log says,
show fields from customers where invoices.customer_id = 49
show fields from orders where invoices.order_id = 58
where there is only one invoice for order 58
and three invoices for customer 49
Just not sure how to customize it to suit.
Thanks again.

I'm sorry for the silly questions.
The problem is about the invoice/show/id page it was great until i created a second order and invoice, then the
@customer.stuff displayed twice, I created a third order and invoice, hence display's three times. I only want it to diplay once. I thought it might be because invoice belongs_to customer so i tried displaying order.stuff (invoice also belongs_to order) and it only displayed just once.
This is the part of the view;

<% for invoice in @customer.invoices %>

Invoice to:

<%= @customer.name %>

<%= @customer.address %>
<% end %>

And this is part of the invoice controller;

def show
@invoice = Invoice.find(params[:id])
@invoice_item = @invoice.invoice_items
@items = @invoice.items
@customer = @invoice.customer
@order = @invoice.order
end

Am I totally off track? Oh, I mean off the rails?
Any help is very much appreciated.
