Any suggestions on how to get my 6 month old to sleep through the night?

I've heard the stuff about making sure she eats enough during the day so she isnt making up missed calories at night and that she may be waking up to eat just out of habit, but a lot of the time she doesnt want to eat in the middle of the night, I just give her her pacifier and she will go back to sleep after a little while. She is usually very cranky though. I would love any recommendations...Thanks
