undefined method add called for ActsAsFerret::Remote::Server

undefined method `add' called for #<ActsAsFerret::Remote::Server:0x7f5be279ea38>

I am currently using ferret (0.11.6) and act_as_ferret (0.4.3)

My project is using rails 2.1.1 and ruby 1.8.6 along with sqlite3 and Webrick.

I can start the ferret server and when I do 'ps aux | grep ferret' in terminal I see the ferret server to be running.

I have a model and controller to create an object that has a title and description. When I am starting my server and try to add an object in the database it is not creating any object and I am getting the following error.

"undefined method `add' called for #<ActsAsFerret::Remote::Server:0x7f5be279ea38>"

I tried to search solution for this problem in google. But haven't found the solution. Please help me to solve the problem. I am a new ferret user and not understanding what exactly to do. Please help me.

I am using active scaffold for my object. And my sample code is as follows

class Object < ActiveRecord::Base

  validates_presence_of :title, :message => "required"

  #searchable fields   acts_as_ferret

end

class Admin::ObjectsController < Admin::BaseController

  active_scaffold :object do |config|     # config.columns = :title, :content     config.columns = :title, :content     config.list.columns = :created_at, :title     config.create.columns = :title, :content     config.update.columns = :title,:content     # config.columns.content   end

end

I attachment has the information I got from Application Trace:

Thanks in advance.

Please help.
