Couldn't find status id

Hi there!

I have a little problem following this video.

While testing if a user 'should update status for the current user when logged in', got the following error:

*1) Error: StatusesControllerTest#test_should_update_status_for_the_current_user_when_logged_in: ActiveRecord::RecordNotFound: Couldn't find Status with id=980190962 [WHERE "statuses"."user_id" = ?] app/controllers/statuses_controller.rb:45:in update' test/controllers/statuses_controller_test.rb:76:inblock in <class:StatusesControllerTest>'

2) Error: StatusesControllerTest#test_should_update_status_when_logged_in: ActiveRecord::RecordNotFound: Couldn't find Status with id=980190962 [WHERE "statuses"."user_id" = ?] app/controllers/statuses_controller.rb:45:in update' test/controllers/statuses_controller_test.rb:70:inblock in <class:StatusesControllerTest>'

12 tests, 24 assertions, 0 failures, 2 errors, 0 skips*

Here's my statuses_controller.rb (lines 44 to 56):

  def update
    @status = current_user.statuses.find(params[:id])
    params[:status].delete(:user_id) if params[:status].has_key?(:user_id)
    respond_to do |format|
      if @status.update(status_params)
        format.html { redirect_to @status, notice: 'Status was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: 'edit' }
        format.json { render json: @status.errors, status: :unprocessable_entity }
      end
    end
  end

Here's my statuses_controller_test.rb:

 test "should update status when logged in" do
    sign_in users(:gustavo)
    put :update, id: @status, status: { content: @status.content }
    assert_redirected_to status_path(assigns(:status))
  end

  test "should update status for the current user when logged in" do
    sign_in users(:gustavo)
    put :update, id: @status, status: { content: @status.content, user_id: users(:paul).id }
    assert_redirected_to status_path(assigns(:status))
    assert_equal assigns(:status).user_id, users(:gustavo).id
  end

At last, my users.yml:

gustavo:
    first_name: "Gustavo"
    last_name: "Paiva"
    email: "gustavorpaiva@gmail.com"
    profile_name: "grpaiva"

paul:
    first_name: "Paul"
    last_name: "McCartney"
    email: "paulmccartney@gmail.com"
    profile_name: "paulpaul"

I'm using Rails 4.0.4, and I've already made some fixtures on treebook's code so it could work perfectly. Should that be the case or am I missing something?

Thanks!
