Ruby on Rails Tutorial - Getting Errors, pulling my hair out - ruby-on-rails

Question

Im following [Michael Hartl's tutorial][1] and did the exercises in Chapter 7, and now have 4 errors that I cant figure out how to fix for the life of me. When I test the production app manually, the errors dont exist at all. So I don't know if there is something wrong with my text development or something, but Im at a total loss so I thought I'd post here to see if my total noobness is blinding me...thanks for your help!
Here's the 4 error messages I'm getting:
Failures:
1) signup with invalid information after submission
Failure/Error: it { should have_selector('title', text: "Sign up") }
expected css "title" with text "Sign up" to return something
# ./spec/requests/user_pages_spec.rb:38:in `block (4 levels) in <top (required)>'
2) signup with invalid information after submission
Failure/Error: it { should have_content('error') }
expected there to be content "error" in "after submission"
# ./spec/requests/user_pages_spec.rb:39:in `block (4 levels) in <top (required)>'
3) signup after saving the user
Failure/Error: it { should have_selector('title', text: user.name) }
NoMethodError:
undefined method `name' for nil:NilClass
# ./spec/requests/user_pages_spec.rb:60:in `block (3 levels) in <top (required)>'
4) signup after saving the user
Failure/Error: it { should have_selector('div.alert.alert-success', text: 'Welcome') }
expected css "div.alert.alert-success" with text "Welcome" to return something

Here's the code on my user_pages_spec.rb:
require 'spec_helper'
require 'spec_helper'
describe "User pages" do
subject { page }
describe "signup page" do
before { visit signup_path }
it { should have_selector('h1', text: 'Sign up') }
it { should have_selector('title', text: full_title('Sign up')) }
end
describe "profile page" do
let(:user) { FactoryGirl.create(:user) }
before { visit user_path(user) }
it { should have_selector('h1', text: user.name) }
it { should have_selector('title', text: user.name) }
end
end
describe "signup" do
before { visit signup_path }
let(:submit) { "Create my account" }
describe "with invalid information" do
it "should not create a user" do
expect { click_button submit }.not_to change(User, :count)
end
describe "after submission" do
before { click_button submit }
it { should have_selector('title', text: "Sign up") }
it { should have_content('error') }
end
end
describe "with valid information" do
before do
fill_in "Name", with: "Example User"
fill_in "Email", with: "user#example.com"
fill_in "Password", with: "foobar"
fill_in "Confirmation", with: "foobar"
end
it "should create a user" do
expect { click_button submit }.to change(User, :count).by(1)
end
end
describe "after saving the user" do
before { click_button submit }
let(:user) { User.find_by_email('user#example.com') }
it { should have_selector('title', text: user.name) }
it { should have_selector('div.alert.alert-success', text: 'Welcome') }
end
end

Here's the template code for views/users/show.html.erb
<% provide(:title, #user.name) %>
<div class="row">
<aside class="span4">
<section>
<h1>
<%= gravatar_for #user %>
<%= #user.name %>
</h1>
</section>
</aside>
</div>
and then here's the users_controller.rb
class UsersController < ApplicationController
def show
#user = User.find(params[:id])
end
def new
#user = User.new
end
def create
#user = User.new(params[:user])
if #user.save
sign_in #user
flash[:success] = "Welcome to the Sample App!"
redirect_to #user
else
render 'new'
end
end
end

Answer 1

Allright y'all,
I dont know if not answering my question was some sort of torturous initiation for noobs in this forum, but after almost 24 hours and a good night sleep, I solved the problem!
After a few G searches, I found that I could be stopping some of the variables from passing through by having "end" in the wrong places. It turns out there were 2 main areas where I was doing this. Once I found and fixed those, all the errors went away.
I will now pat myself on the back. I hope this helps any total noobs who run into this same problem in the future.
