rspec users - Jul 2008 - Errors in controller test

I catch very strange error while testing:

NoMethodError in ''VotingsController handling POST /votings should
redirect
to index if success''
You have a nil object when you didn''t expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.save

Strange, because I''m stub my @voting.

This is my test:

describe "handling POST /votings" do
    
    before(:each) do
      login_user #login helper, stub login_requered and return @user
      @voting = mock_model(Voting)
      controller.stub!(:create_voting).and_return @voting
    end
    
    def do_post
      post :create
    end      
    
    it "should redirect to index if success" do      
      @voting.stub!(:save).and_return true
      do_post
      response.should redirect_to(votings_path)
    end

    #something else   
     
  end

And there is my controller:

class VotingsController < ApplicationController 
  before_filter :create_voting, :only => [:create]

  #some stuff there

  def create    
    respond_to do |format|                  
      if @voting.save
       ...
      end
    end
  end

  private

  def create_voting 
    @voting = Voting.new(params[:voting])
    @voting.author = current_user
  end

end

P.S. but this tested fine

def create    
    @voting = Voting.new(params[:voting])
    @voting.author = current_user
    respond_to do |format|                  
      if @voting.save
       ...
      end
    end
  end

You are stubbing the wrong method, try this:

   before(:each) do
     login_user #login helper, stub login_requered and return @user
     @voting = mock_model(Voting)
     Voting.stub!(:new).and_return( @voting )
   end
