Subject: Getting (var = false) to return true?

In Rails (it's more of a Ruby question though ;) ), I have:

def before_update
  @var = get_old_var_value
end

and if get_old_var_value returns a false value it causes the update to 
cancel. Is there some function that'll return true after setting the 
var? Something like, oh I dunno, set_var(:var, get_old_var_value). 
Rails' write_attribute also seems to return the value of the var (so 
false causes problems with it too). I know I can just simply do this:

def before_update
  @var = get_old_var_value
  true
end

But I'm just curious if there are other approaches.

Thanks,
Joe
