From title case to sentence case

Question

I'm trying to write a helper to translate a string from "something_like_this" to "Something like this". I'm using "something_like_this".titlecase to get it to "Something Like This" but I'm stuck lowercasing every uppercase letter except the first.

I suppose I'm looking for something like this:

def write_sentence
  string.titlecase.gsub!(/UPPERCASE-TO-LOWERCASE-EXCEPT-FIRST/)
  #that should be something to lowercase everything except the first letter
  return string
end

So in the view I could just write string.write_sentence and have it return exactly what I want. Any thoughts?

Thanks!

EDIT

I should mention that the string can sometimes be just one word, in which case the string should be converted from "something" to "Something".

Try this,

"something_like_this".humanize
