Answer 1

Since this is old, but google still comes here, a small note about the main answer, which is essentially good, but some things have changed:

• see answer about jquery having changed .data("uiAutocomplete") to .data("autocomplete")

• Also i would recommend a separate route on the resource collection that just handles json

• use rabl to create smaller json (or pluck for larger models)
• ilike , not like, for case insensitive
• the % in front, so the search is not just start_with.
• valiable traversal in the methods, like item.person.name are just item.name (so drop the .person)
• use coffee (in haml)
• use a limit, and where as in: Person.where('given_name ilike ?', "%#{params[:term]}%").limit(20)
