Noel-- Can you be more specific than "didn't work"? Really, it looks like what you've described is just taking two (or possibly) scalars from the database and concatenating them as strings. If that's the case, why not just do it in the controller instead of having a separate partial?
WRT why Haml adds the newline: I dunno, it always has added one when you have a newline in your code. Rendering a partial that contains a single line in a loop would suggest that the newline is appropriate. I'm not sure that erb is doing the right thing.
