spec does not evaluate expression

It seems my specs has stopped thinking. The spec does not evaluate the
argument in page.should have_content("Logga in på #{farm.name}") as
an expression but as a string. I have tried other ways of writing the
same expression but it doesn't help.

This is my very simple spec:

# encoding: utf-8
require 'spec_helper'
include Warden::Test::Helpers

describe "Pupils" do
  it "show login page for farm" do
    farm = Factory.create(:farm)
    visit new_pupil_session_path
    page.should have_content("Logga in på #{farm.name}")
  end
end

The error I get when I runt it is:
1) Pupils show login page for farm
     Failure/Error: page.should have_content("Logga in på
#{farm.name}")
       expected there to be content "Logga in på farm_long2" in
"horsemanager\

So why does it not evaluate #{farm.name}? It's probably something
stupid I have missed.

Appreciate any help!

PLEASE FORGET THIS!! IT WAS PURE STUPIDITY!!!
