undefined method `+@' for " ":String
Submitted by greg on Mon, 06/16/2008 - 21:23
After trying a few things, I realized that Rails (Ruby, really) was complaining that the ' ' operator wasn't at the end of the line, so it wasn't trying to concatenate the strings as I expected. So flipping them to the end of the line fixed the error.
I was tired, or maybe I would've started that way. In any case, hopefully this will let someone else save a few moments. Live and learn.
