Thanks! I missed that. I am using eager_graph because i need to filter by fields on the associated objects. Is there a cleaner way? (i want something like select T.* from T join T2 using (...) where T2.x=y limit 1;) And, if I need to make the join, why would I want to avoid the eager loading of the associated object?
BTW, why does .first uses each? I would assumed .first was equivalent to .limit(1).all[0] Thanks!
