Im trying to follow the railscasts complex forms tutorial, but im  
doing it with :through realted tables and im having some problems.

Ive made a pastie of the error and related files so its easier to  
read: [Parked at Loopia](http://pastie.caboo.se/181691)

Any thoughts? Thanks.

run ruby -c file\_name  
on each file to make sure they pass [I guess they do]  
do a require\_dependency in one of the other?

Thanks again Roger.

Yea you were right, the problem was with the name of the join table  
and model. I thought that was the naming convention, but thats  
apparently for has\_and\_belongs\_to\_many, and its better to have a  
meaningful singular name for the join table using :through.

Thanks again 😉

# should say ok

doing require\_dependency  
would be  
at the top of one file,w here it errs, add  
require\_dependency ‘app/models/orders\_sandwiches’

I wonder if  
class OrdersSandwiches \< ActiveRecord::Base  
should be OrdersSandwich  
though 😛

I agree–their naming syntax is somehow lacking, in this instance 🙂
