Rails Tutorial 8.25

Question

I am currently working through Rails Tutorial 4.0. I have reached completed everything up to 8.2.5. For the life of me I can't get a user to be able to sign-in. I have all my valid users specs failing and when I try in the browser, I always get username/password combination failure messages. I have inspected the params debug and the email and password I am using match what I set them to when signing up. The user exists in the database. The only thing I can think of is something with the encryption of the remember_token or something. Any help would be great

factories.rb

FactoryGirl.define do
  factory :user do
    name "James"
    email "test@example.com"
    password "foobar"
    password_confirmation "foobar"
  end
end

user.rb

class User < ActiveRecord::Base
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-]+(\.[a-z]+).[a-z]+\z/i

  validates :name  , presence: true, length: { maximum: 50 }
  validates :email , presence: true, format: { with: VALID_EMAIL_REGEX },
    uniqueness: { case_sensitive: false }
  validates :password, length: { minimum: 6 }

  before_save{ email.downcase! }
  before_create :create_remember_token
  has_secure_password

  def User.new_remember_token
    SecureRandom.urlsafe_base64
  end

  def User.encrypt(token)
    Digest::SHA1.hexdigest(token.to_s)
  end

  private
  def create_remember_token
    self.remember_token = User.encrypt(User.new_remember_token)
  end
end

      let(:user) { FactoryGirl.create(:user) }

      it { should have_link('Sign Out', href: signout_path) }
      it { should_not have_link('Sign In', href: signin_path) }
    end
  end

Answer 1

Stepping away and coming back at another time works best. The problem I had was in the views/sessions/new.html.erb which seems like the only file I wasn't looking at at the time. I accidentally had the password label and password_field using symbol :Password instead of :password.
