Hi there, assume that:
1 we have the following situation: Book :has_many Pages :has_many Illustrations ==== ===== ============= 2 certain pages have NO illustrations 3 the following 2 cases: A) Book.find(:all, :joins => [:pages => [:illustrations]]) B) Book.find(:all, :include => [:pages => [:illustrations]]) Question: Is it correct that: - in case A), the books containing pages WITHOUT any illustrations will NOT show up in the results - whereas in case B), these books WILL show up? (Personally, I thought that the main difference between :joins and :include was the "eager loading" part.) Thanks for any explanation for this!
