Status of jQuery automatic completion with Rails 3 and 4 -

-

i'm new rails. company switching projects rails 3 rails 4, i'd understand packaging of automatic completion in both.

from understanding there rails plugin, auto_complete, i'm guessing used prototype. of version 3, rails agnostic of javascript frameworks automatic completion functionality moved gems. jquery version of gem, rails3-jquery-autocomplete, makes use of jquery ui widget, autocomplete.

now, in attempting figure of out removed 'jquery-rails' gemfile of rails 4 project, can somehow still require both 'jquery' , 'jquery.ui.autocomplete' in application manifest. since jquery included in rails now, still need gem make rails 4 work jquery's autocomplete? like, rails4-jquery-autocomplete? think so, what's confusing me don't method undefined error when use 'text_field_with_auto_complete'. instead, unmatched route error.
