How to get Jquery UI Autocomplete working with Rails 4?

Question

I\'m using Rails 4.0.2 with jquery-rails (3.1.0) and jquery-ui-rails (4.1.1) gems. I\'m trying to add Autocomplete to the search form (using Bootstrap 3.1.0):

Answer 1

Judging by your note, it looks like you're not fetching the param correctly in your controller, so try:

render json: @products.where("name ILIKE ?", "%#{params[:term]}%")

Answer 2

  def autocomplete
    @products = Product.order(:name).where("name LIKE ?", "%#{params[:term]}%")
    respond_to do |format|
      format.html
      format.json { 
        render json: @products.map(&:name).to_json
      }
    end
  end
