@customer.deliveries.count give 5 while the table has 6 lines.
Why?
I think it’s all ok but I cannot undestand why the each cycle give me
one more line in the table.

Why?
Do you mean the table has a total of six rows? If yes then there is
the header row before the 5 data rows.

No no, including the header I have a total of 7 rows.
If @customer.deliveries.count is 5 then I expect 6 rows including the
header, instead I have 7 rows including the header.

The rows are 8 including the header.
Finally, unless this is rails 3, you should be using
h(product.description) for example, in case there is some html in the
description.
I’m using rails 3.
Consider what would happen if the description included
for example.
I always have one more row.
well the header does not count, just the row of the database, maybe
the last dont its not a row, maybe is the append contentd of the last
row,
check out well your html format

Also I suggest displaying @customer.deliveries.count in the page to
check it really is what you think.

maybe is the way you show the data why not prove like these
<% delivery.products.each do |product| %>
<%=“Nothing, just to see if 5 row is display it” %>,
<% end %>

I think it’ s ok.
It’ all under <% @customer.deliveries.each do |delivery| %> so if
@customer.deliveries.count gives 5 I’d expect 5 rows.
clear the console where you are running rails server, then start over
and enter to the view and paste the
result of the consol in pastie.org

If you do not already know how to use ruby-debug to break into your
code then have a look at the Rails Guide on debugging, then at this
point insert
<% debugger %>
and when you run it will break here and you can inspect the variables
and see what is going on.
One possiblity, have you changed @customer or its deliveries since it
was read from the database in such a way that the number of records in
the database (deliveries.count) does not match the current number of
deliveries in the object in memory?

there is always one more row 
the result of
SELECT “deliveries”.* FROM “deliveries” WHERE (“deliveries”.customer_id
= 65145

<%= @customer.deliveries.count %>

What does deliveries.size give?
What are the results of breaking in with the debugger and inspecting the
data
You have not answered whether you have done something in memory to
deliveries since @customer was picked up from the database (presumably
in the controller). Have you added another delivery in the controller
or view?
Colin
give us the controller and the view
but i think what Colin want to see, is the index page , where you are
printing the collection
