[Rails] Re: Combining multiple finds into one result

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.
