MS SQL (legacy) relations not working

I have my app talking to the MS SQL database. meaning I can retrieve
data from it.
I have an Office table. and it has a column called ‘Marketing’ that is
a foreign key to the marketing tables primary key.

so I was have trouble and I set up a test environment on mac using
I set the tables up the same way as the MQ SQL server.

here are the models

class Office < ActiveRecord::Base
set_table_name “Office”
self.primary_key = “OfficeID”

belongs_to :marketing,
:class_name => “Marketing”,
:foreign_key => “Marketing”

class Marketing < ActiveRecord::Base
set_table_name “marketing”
self.primary_key = “marketingid”

has_many :offices

/*** controller ***/
class OfficeController < ApplicationController

def index
@offices = Office.find(:all)

/*** index.rhtm ***/

<% for office in @offices %>
<%= office.Name %> - <%= %>
<% end %>
<%= debug @offices %>

this code works with the locomotive set up (MySQL database) and the
instant rails set up with MySQL database
but when I use the same code on the instantrails using the MS SQL
server I get this error.

You have a nil object when you didn’t expect it!
The error occurred while evaluating nil.first_name

I am confused.
if I take out the <%= %> part of code it
runs and in the debug it shows “Marketing”=>4 - which is correct but
it also doesn’t show the marketing object within the office object.

anybody have any ideas?
