user privileges to roles and features using rails and rspec - ruby-on-rails

Question

i am new about rails and respect, so i hope found the answer here,
i have some models here, and all of it have many to many relations
user -- role_user -- role -- role_feature -- feature
role_user and role_feature is the middle table to connect the many to many relations, I have completed all the controller crud and the model relations table, and also tested both of it with rspec and it is 100% coverage, so dont worry about it. and i haven't do anything about views, just model, controller and rspect.
Now I want to create privilege/permissions for each user in accessing existing features, so each user has a role and the role has many features,
in the file seeds.rb
RoleUser.where(role_id: 1, user_id:1).first_or_create;
Role.where(holding_company_id: 1, name: 'Area Index').first_or_create;
RoleFeature.where(role_id: 1, feature_id:1).first_or_create;
Feature.where(name: 'Area Index', key: 'area_index').first_or_create;
Feature.where(name: 'Area Create', key: 'area_create').first_or_create;
in the file area.rb (i take example area)
class AreasController < ApplicationController
before_filter :check_access
def index
if params[:per_page].blank? && params[:page].blank?
areas = Area.where(holding_company_id: current_holding_company.id)
else
areas = Area.where(holding_company_id: current_holding_company.id).paginate(page: params[:page], per_page: params[:per_page])
end
respond_to do |format|
format.json { render json: areas.to_json, status: 200 }
end
end
def create
end
def update
end
def show
end
def destroy
end
protected
def check_access
case params[:action]
when 'index'
unless current_user.roles.features.include? (area_index)
render nothing: true, status: 200
end
end
end
end
and the spec is
require 'spec_helper'
describe AreasController, :type => :controller do
before(:each) do
#token = FactoryGirl.create(:token)
#area = FactoryGirl.create(:area_1)
FactoryGirl.create(:area_2)
FactoryGirl.create(:area_3)
end
describe "GET 'index'" do
it "returns http success for json without pagination" do
get 'index', token: #token.token_string, format: :json
expect(response.status).to eq(200)
expect(JSON.parse(response.body).count).to eq(3)
expect(Area.count).to eq(3)
end
it "returns http success for json with pagination" do
get 'index', token: #token.token_string, format: :json, page: 1, per_page: 2
expect(response.status).to eq(200)
expect(JSON.parse(response.body).count).to eq(2)
end
end
describe "POST 'create'" do
end
describe "PUT 'update'" do
end
describe "GET 'show'" do
end
describe "DELETE 'destroy'" do
end
end
and the problem is there is an error/failure while testing it with rspec, its said undefined method role, i try to fix it , i spent hours just for browse it on internet, but it's useless. so i hope this is the final chance for me, i need your help guys...
