NameError in CustomersController#index

I''m new to Rails.  I finished the Cookbook tut. no problem. 
I''m
trying to start a project of my own, follow the same instructions but
the difference is I created the database myself.
After I create the scaffolds and try them out I get this error

 NameError in CustomersController#index

uninitialized constant Customer

RAILS_ROOT: ./script/../config/..

Re: NameError in CustomersController#index

It''s kind of hard to guess with absolutely no code.
Do you have a file in app/models called customer.rb which contains  
the definition of the Customer class?

Re: NameError in CustomersController#index

Sorry, Like I said i''m pretty new at this.
The files are there but they were empty.  I put a "has_many :leases"
to the customer.rb.  After doing that I restarted my mongrel server
and get the same error.
All the code in the app is just from running "ruby script\generate
customer customer" the the customer database looks like this:
 create_table "customers", :id => false, :force => true do |t|
    t.column "CustID",    :integer, :limit => 10, :null => false
    t.column "CustFirst", :string,  :limit => 20
    t.column "CustLast",  :string,  :limit => 30
    t.column "CustCo",    :string,  :limit => 50
    t.column "CustAddr",  :string,  :limit => 50
    t.column "CustCity",  :string,  :limit => 20
    t.column "CustPO",    :string,  :limit => 7
  end

Doesn''t make sense. There is no "customer" generator.

You should be doing:

   ruby script/generate model customer

which will create several things, including a migration in db/migrate
to create the table and a model in app/models/customer.rb (also
creates a unit test and test fixture file).

The app/models/customer.rb needs to contain a model class:

  class Customer < ActiveRecord::Base
    has_many :leases
  end

This declaration assumes a bunch of things:

  * you have a table called "customers"
  * you have another table called "leases" with a
"customer_id" integer column
  * you have a model file called app/models/lease.rb, which declares:

     class Lease < ActiveRecord::Base
       belongs_to :customer        # not required, but customary
     end

If you''re starting an app from scratch, use the generators. They
ensure that everything is created correctly.

Oh, I missed that. So you also need to tell Rails that your id column
is non-standard:

  class Customer < ActiveRecord::Base
    set_primary_key ''CustID''
    ...

  end

Re: NameError in CustomersController#index

sorry I missed the generator on that last e-mail.  What I typed to
generate my app was
"ruby script\generate scaffold customers customers"  because I created
the database first that way it created my controllers & stuff.

I started from scratch again and run
"ruby script\generate scaffold customers customers"
I run
"ruby script/generate model customers" too just in case I needed it.
I added to customers.rb:
set_primary_key ''CustID''
has_many :leases
and to leases.rb:
belongs_to :customer
I still get the same error

model, in customers.rb
