Ruby On Rails 3 Tutorial Chap 8: Unit tests not passing - ruby-on-rails

Question

I'm working through Hartl's book and I'm up to chapter 8. I've written some tests that I believe should be passing. I've quadruple checked my code against what's in the book, and double checked it against what's in the book's github repo, but I'm stumped. I'm getting the following errors from RSpec:
Failures:
1) UsersController POST 'create' should redirect to the user "show" page
Failure/Error: response.should redirect_to(user_path(assigns(:user)))
ActionController::RoutingError:
No route matches {:action=>"show", :controller=>"users", :id=>#<User id: nil, name: nil, email: nil, created_at: nil, updated_at: nil, encrypted_password: nil, salt: nil>}
# ./spec/controllers/users_controller_spec.rb:93:in `block (3 levels) in <top (required)>'
2) UsersController POST 'create' should have a welcome message
Failure/Error: flash[:success].should =~ /welcome to the sample app/i
expected: /welcome to the sample app/i
got: nil (using =~)
# ./spec/controllers/users_controller_spec.rb:98:in `block (3 levels) in <top (required)>'
Finished in 0.83875 seconds
46 examples, 2 failures
Like I said, I've checked the code again and again. Restarted spork, restarted rails server, ran without spork. I've checked it against the code in the book and in the github repo. I've even copy/pasted the spec and controller code in the github repo, but all to no avail.
I'm stumped. It's late and I need to crash. :)
Hopefully one of you guys can see something I'm not. Here's what I've got so far...
users_controller_spec.rb
require 'spec_helper'
describe UsersController do
render_views
# ...
describe "POST 'create'" do
# ...
describe 'success' do
before(:each) do
#attr = { :name => 'New User', :email => 'some-email#gmail.com', :password => 'foobar', :password_confirmation => 'foobar' }
end
it 'should create a new user' do
lambda do
post :create, :user => #attr
end.should change(User, :count).by(1)
end
end
it 'should redirect to the user "show" page' do
post :create, :user => #attr
response.should redirect_to(user_path(assigns(:user)))
end
it 'should have a welcome message' do
post :create, :user => #attr
flash[:success].should =~ /welcome to the sample app/i
end
end
end
users_controller.rb
class UsersController < ApplicationController
def new
#user = User.new
#title = 'Sign up'
end
def show
#user = User.find params[:id]
#title = #user.name
end
def create
#user = User.new(params[:user])
if #user.save
flash[:success] = 'Welcome to the Sample App!'
redirect_to #user
else
#title = 'Sign up'
render 'new'
end
end
end
user.rb
class User < ActiveRecord::Base
# Virtual properties (don't exist in db)
attr_accessor :password
# Accessible properties
attr_accessible :name, :email, :password, :password_confirmation
email_regex = /\A[\w+\-.]+#[a-z\d\-.]+\.[a-z]+\z/i
validates :name, :presence => true,
:length => { :maximum => 50 }
validates :email, :presence => true,
:format => { :with => email_regex },
:uniqueness => { :case_sensitive => false }
validates :password, :presence => true,
:confirmation => true,
:length => { :within => 6..40 }
before_save :encrypt_password
# Return true if the user's password matches the submitted password
def has_password?(submitted_password)
# Compare encrypted_password with the encrypted version of submitted_password
encrypted_password == encrypt(submitted_password)
end
# Static/Class methods
def self.authenticate(email, submitted_password)
user = find_by_email email
return nil if user.nil?
return user if user.has_password? submitted_password
end
# Private functionality.
# Anything after the 'private' pragma will be inaccessable from outside the class
private
def encrypt_password
self.salt = make_salt if new_record? # Using ActiveRecord goodness to make sure this only gets created once.
self.encrypted_password = encrypt(password)
end
def encrypt(string)
secure_hash("#{salt}--#{string}")
end
def make_salt
secure_hash("#{Time.now.utc}--#{password}")
end
def secure_hash(string)
Digest::SHA2.hexdigest(string)
end
end
routes.rb
SampleApp::Application.routes.draw do
#get '/users/new'
resources :users
match '/signup' => 'users#new'
match '/about' => 'pages#about'
match '/contact' => 'pages#contact'
match '/help' => 'pages#help'
root :to => 'pages#home'
end
Thanks in advance. If you guys really want to dig through or if I've missed something in my post, here's my code.
I'm very new to rails, and absolutely love it so far. Any help will be greatly appreciated.

Answer 1

Look closely at your users_controller_spec "success" spec: when will it create #attr? Before each test, or just before the "should create a new user" test? You use it in all the "POST 'create'" tests...
Once you make that non-spec-specific your tests will pass.
(By the way, having the code up in git is handy, but only if the code you're posting is actually checked in, otherwise... not as much ;)

Answer 2

your
it "should redirect to the user show page"
and
it "should have a welcome message"
is outside of the
describe "success" do
loop
