rspec users - Nov 2010 - Not sure why let is not doing the same thing as traditional test

Here is my test which passes.

   before do
        @page = Factory(:page)
        @note = Factory(:note, :page => @page, :title => ''super
cool'')
      end
      it ''has size 1'' do
        @page.notes.size.should == 1
      end


I read rspec book and wanted to use let. Here is my implementation.
And it fails

     let(:page) { Factory(:page) }
      let(:note) { Factory(:note, :page => page, :title => ''super
cool'') }
      it ''has size 1'' do
        page.notes.size.should == 1
      end

In the log I noticed that when I switched to using let then no note
record is being created.

Here is relevant gem file

group :development, :test do
  gem ''mongrel''
  gem ''capistrano'', ">= 2.5.19"
  gem ''capistrano-ext''

  gem "factory_girl_rails"

  gem "database_cleaner"
  gem "shoulda"

  gem "rspec-rails", ">= 2.0.1"
  gem "cucumber-rails", ">= 0.3.2"
  gem "capybara", "= 0.4.0"
  gem "launchy"
  gem "redgreen"
  gem "faker"
  gem "mongrel"
end


Is let lazy? It seems since I am not using note the record is not
being created.

The book said that output is memoized. Nothing more than that.

I''m under the weather so I won''t be able to give you a
thorough
answer.

#let - The block is executed when you call it.
#let! - The block is "wrapped" in a before(:each) filter.

So, you want to use #let!
