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/…

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?

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:

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

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

It’s expecting a customer model (in a customer.rb file), since you’ve  
said belongs\_to :customer, but instead you’ve created a customers

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

class Customer \< ActiveRecord::Base

…
