Is there any way to get the edge rails feature that allows you to do use  
\<\< to add an object to a relationship, just like in the HABTM. I know  
Josh S. talked about about how someone released a fix for it, but it  
didnt seem to make it into Rails 1.2. Any ideas?

I tried extending the relationship, but this method seems a little  
hackish:

has\_many :through=\>x do

def \<\<(value)  
JoinTable.create()  
end  
end

However, Im having a little trouble getting the id for the object since  
its passing through another relationship. Any ideas.

Thanks in advance.
