So this functionality isn’t supported natively in Rails 3 (or any  
versions before that for that matter) But I had found a work around  
via this blog post:  
[http://geoff.evason.name/2010/04/23/nested-has\_many-through-in-rails-or-how-to-do-a-3-table-join/](http://geoff.evason.name/2010/04/23/nested-has_many-through-in-rails-or-how-to-do-a-3-table-join/)

This didn’t work on Rails 3 because it wasn’t able to properly build  
the query from the join with symbols. I was however, able to get it to  
work using a singular symbol for the model relation to the child, and  
then manually writing the SQL from the next nest up. Is this the most  
efficient way to go? Or am I missing something here?
