Rspec controller error? expecting <"index"> but rendering with <""> or it's working? - ruby-on-rails-3

Question

I'm new with rspec test and maybe there are something that I dont undertand.
if can any help me, I really appreciate some help.
File Structure:
app/models/booking.rb
app/models/user.rb
app/models/role.rb
app/models/ability.rb
app/controllers/bookings_controller.rb
app/views/bookings/index.html.erb
app/views/dashboard/index.html.erb
app/spec/controllers/bookings_controller_spec.rb
I read this link with a similar problem but it isn't solved
Rspec controller error expecting <"index"> but rendering with <"">
is similar, because if I change this line:
it 'should not render index template from bookings' do
get :index
=> response.should_not render_template(:index)
end
for this other:
it 'should not render index template from bookings' do
get :index
=> response.should render_template(:index)
end
I get the same mistake that in the link
expecting <"index"> but rendering with <"">
and I don't know why?
Here's my Code:
My Spec:
describe BookingsController do
context 'as guest' do
before(:each) do
#user = User.new(:email => 'mail_admin#test.com',
:username => 'admin',
:password => 'password_admin',
:password_confirmation => 'password_admin')
#user.save
#when i save, with gem CanCan i assign a default role to #user
#with the default role the user only can see the views/dashboard/index.html.erb
end
it 'should not render index template from bookings' do
get :index
response.should_not render_template(:index)
end
end
end
Controller:
class BookingsController < ApplicationController
load_and_authorize_resource
def index
...
end
def show
...
end
end
My model:
class Booking < Activerecord::Base
paginates_per 20
def
...
end
def
...
end
end
User:
Class User < ActiveRecord::Base
after_save :set_default_role
rolify
.
.
.
.
def set_default_role
self.add_role :default
end
end
Role:
class Role < ActiveRecord::Base
ROLES = {"admin" => "Admin", "default" => "Default"}
.
.
.
.
scopify
end
Ability:
class Ability
include CanCan::Ability
def initialize(user)
user ||= User.new
if user.has_role? :admin
can :manage, :all
elsif user.has_role? :data_consistency
can :read, Booking
end
end
end

Answer 1

CanCan authorizes model access not controller actions. For most other actions these two are more or less the same thing, but not for the index. On the index action CanCan adds a scope to the query for records that includes your authorization restrictions.
What this means is that your guest user will simply not be able to see any records, but the view will still render.
What you want is authentication (ie Devise) and use it from a before_filter in each controller that requires an authenticated user to access.
class BookingsController < ApplicationController
load_and_authorize_resource # Handles authorization
before_filter !authenticate_user # Handles authentication (included with Devise)
...
end

Answer 2

In my case, the problem was solved in before(:each) block!
My code works like this:
before :each do
#user = User.new(:email => 'mail_admin#test.com',
:username => 'admin',
:password => 'password_admin',
:password_confirmation => 'password_admin')
#user.confirm!
sign_in #user
end
