rspec users - Oct 2009 - How can I spec protect method

How can I spec the 3rd line of my controller?
update_successful, error_msg = update_channels_association

  def create
    @user = User.new(get_param(:user, :hash))

    if @user.save
      update_successful, error_msg = update_channels_association
      set_flash_if update_successful,
:resource_successfully_created.t(:resource => :user.t[:one]), error_msg

      redirect_to @user
    else
      render :action => :new
    end
  end
**************************
My spec

describe UsersController do  
  describe "POST create" do
    ##############################################################
    should_require_login :post, :create    
    
    ##############################################################
    describe "authenticated user" do 
      ##############################################################
      before(:each) do 
        login_as_user
        
        @user = mock_model(User, :save => nil)
        User.stub!(:new).and_return(@user)
        @params = {''name'' => ''Mary''}  
      end 

      ##############################################################
      def do_post
        post :create
      end
      
      ##############################################################
      it "should build a new user" do 
        User.should_receive(:new).with(@params).and_return(@user)
        post :create, :user => @params 
      end

      ##############################################################
      it "should save the user" do 
        @user.should_receive(:save) 
        do_post
      end 
      
      ##############################################################
      context "when the user saves successfully" do 
        before(:each) do 
          @user.stub!(:save).and_return true 
          controller.should_receive(:update_channels_association)
        end

           
        it "should set a flash[:notice] user" do
          do_post 
          flash[:notice].should =:resource_successfully_created.t(:resource
=> :user.t[:one])
        end
*************************

The error
''UsersController POST create authenticated user when the user saves
successfully should set a flash[:notice] user'' FAILED
expected: "Usu?rio criado(a) com sucesso.",
     got: nil (using ==)

I know it is missing to verify the local variable update_successful.

If anyone can help me.
Cheers 
EM

What does that method do to the other objects in your domain? Can you  
describe that behaviour easily using mocks and stubs?

If not, you would be best to move the method out of the controller and  
onto another class, such as the User model. This is called ''listening  
to your tests''[1]
