I have a model called Resource that has tags from acts-as-taggable-on. I'd like to use jquery-autocomplete to make this almost exactly like stackoverflow has for tags (new ones can be created, but it suggests similar ones first with a count). Everything I've seen for this seemed like a really bad hack and didn't work well. Either they didn't work, or worked inconsistently.
What's the best way of achieving stackoverflow-like tagging in Rails 3?
