I wonder if you can have more than one has_many :through association between 2 models. For example... I have a model Teacher and a model Class Now, 1 Teacher works in many Classes, right?.

I am not sure how to go about this but I suspect I

I know this has been rehashed many times, but I don''t get it. I can''t find it documented to were I understand all the parts.

They also do not give enough information to understand what is going on. In

I have a problem that surfaced in my attempt to upgrade my application to Rails 1.1. We have a STI model on the "belongs_to" side of a has_many/belongs_to relationship. All my unit tests for this model pass, and the relationships all seem to work fine. But in my functional tests, I''m getting errors. I''ve traced it back into the call to the has_many
