I didn’t find exactly an answer on this one, so I’d like to get a
clarification from folks who live & breathe HABTM.
(and yes, I have a bars_foos table in my db)
bar = Bar.new
foo = Foo.new
My first assert passes just fine. But the 2nd fails. Am I wrong on the
concepts of HABTM? Shouldn’t the << operator add to the join table and
therefore the next find from either object return a non-empty array?
