Ahh that works, thanks! I think I had the general idea but I think every time I tried
@a = [] I tried @a += A.find_by_id(some_id) while every time I tried @a << A.find_by_id(some_id) I never tried the @a = [] ....whoops, thanks for all the help. Plus never seen @a.compact!, helps a lot :) btw, in general what I was looking for was a way to put the .find methods inside a loop and combine all the results into one result, everything else was just fluff.
