hello,

how can i use has\_many through for class further then 2 levels  
i have 4 classes :  
Product  
StoreEntry  
Store  
StoreShippingCountry

and i try to access StoreShippingCountry from Product

what i do :

class Product \< ActiveRecord::Base  
has\_many :store\_entries  
has\_many :stores,  
:through =\> :store\_entries  
has\_many :store\_shipping\_countries,  
:through =\> :store\_entries,  
:source =\> :stores  
end

and here is the error i recieve :  
Could not find the source association(s) :stores in model StoreEntry.  
Try 'has\_many :store\_shipping\_countries, :through  
=\> :store\_entries, :source =\> '. Is it one  
of :issues, :store, :prices, :store\_shipping\_countries, :guarantees,  
:product,  
or :actions?

Can someone help me?
