While using rspec i am constantly getting the same error - ruby-on-rails

Question

I am getting the same Error on running rspec that is :-
"Undefined Method - authorize_manage_partner_links"
I am using CANCAN gem in my Gemfile for authorization purposes and i am using Rails version 3.2 and Ruby version 1.9.2.
Please suggest what to do as i am totally new to rspec and rails. I am using a testing database, on importing the database for the first time, when i am running rspec it is showing successful but after that it is showing this error on running the same rspec file. I am using FactoryGirl. and i have defined everything in my factoryrb file as well.
This is my controller--
require 'will_paginate/array'
class PartnerLinksController < ApplicationController
#load_and_authorize_resource
before_filter :authorize_manage_partner_links!
layout "backoffice"
def index
#partner_links = PartnerLink.all
if params[:sortby]
#partner_links = #partner_links.sort_by {|p| p.name} if params[:sortby] == "up"
#partner_links = #partner_links.sort_by {|p| p.name}.reverse if params[:sortby] == "down"
else
#partner_links = #partner_links.sort_by {|p| p.name}
end
total = #partner_links.size
#partner_links = #partner_links.paginate(:page => params[:page], :per_page => 20)
page = params[:page]
if !page
page = 1
end
render :locals => {:total => total, :page => page, :sortby => params[:sortby], :partner_link => #partner_link}
end
def new
#partner_link = PartnerLink.new
end
def edit
#partner_link = PartnerLink.find(params[:id])
end
def create
#partner_link = PartnerLink.new(params[:partner_link])
if #partner_link.save
redirect_to partner_links_url
else
render "new"
end
end
def update
#partner_link = PartnerLink.find(params[:id])
if #partner_link.update_attributes(params[:partner_link])
redirect_to partner_links_url
else
render "edit"
end
end
def destroy
#partner_link = PartnerLink.find(params[:id])
#partner_link.destroy
redirect_to partner_links_url
end
end
This is my rspec controller that i am using--
require 'spec_helper'
describe PartnerLinksController do
before do
FactoryGirl.create(:partner_link)
role_permission
admin_role
user
currency
category
merchant
cart
deal
sign_in user
end
let(:role_permission) {FactoryGirl.create(:role_permission)}
let(:currency) {FactoryGirl.create(:currency)}
let(:merchant) {FactoryGirl.create(:merchant)}
let(:cart) {FactoryGirl.create(:cart)}
let(:deal) {FactoryGirl.create(:deal)}
let(:category) {FactoryGirl.create(:category)}
let(:authentication) {FactoryGirl.create(:authentication)}
let(:user) {FactoryGirl.create(:user)}
let(:admin_role) {FactoryGirl.create(:admin_role)}
describe "index" do
it "Should display all the partner links" do
get :index
end
end
describe "new" do
it "Should create all the partner links" do
get :new
end
end
describe "create" do
it "Should create new all the partner links" do
get :create
end
end
describe "update" do
it "Should update all the partner links" do
get :update
end
end
describe "destroy" do
it "Should delete all the partner links" do
get :destroy
end
end
end
