How do I select a value from a database populated dropdown with Capybara?

I have 2 models: Venue and Event. Venue has_many :events and Event belongs_to :venue.

My events/new form has the following fields

Now I'm trying to test this with RSpec and Capybara. Here's my feature:

require 'spec_helper'

feature "Events" do
  let(:venue) { FactoryGirl.create(:venue) }
  let(:event) { FactoryGirl.create(:event, venue: venue) }

  scenario "Creating event as guest" do
    visit root_path
    click_link "Submit Event"
    fill_in "Title", with: event.title
    click_button "Submit"
    expect(page).to have_content("Event has been created.")
    expect(page).to have_content(event.title)
  end
end

My factories look like this:

FactoryGirl.define do
  factory :event do
    date "2014-02-27"
    time "10:00am"
    title "Slayer"
  end
end

FactoryGirl.define do
  factory :venue do
    name "Example Venue"
    url "http://www.example.com"
    address "123 Main St., Chicago, IL"
  end
end

When I run this spec I get the following error:

 Failure/Error: click_button "Submit"
 ActionView::Template::Error:
   Couldn't find Venue without an ID

I'm guessing this has something to do with the fact that the Venue field is not populated in the test environment?

using let is lazy, so your database call will get executed here:

  scenario "Creating event as guest" do
    visit root_path
    click_link "Submit Event"
    fill_in "Title", with: event.title # <------------------- evaluated!
    click_button "Submit"
    expect(page).to have_content("Event has been created.")
    expect(page).to have_content(event.title)
  end

what you probably want is this:

feature "Events" do
  background do
    @event = FactoryGirl.create(:event, venue: FactoryGirl.create(:venue))
  end

  scenario "Creating event as guest" do
    visit root_path
    click_link "Submit Event"
    fill_in "Title", with: @event.title
    click_button "Submit"
    expect(page).to have_content("Event has been created.")
    expect(page).to have_content(@event.title)
  end
end

you could also use let! which executes directly, but i think the setup block is much clearer.
