Authentication signin with valid information

Question

I am working on Michael Hartl's Rails Tutorial, Chapter 8.2.4: http://www.railstutorial.org/book/sign_in_out#sec-changing_the_layout_links

So far, everything seems to have worked great.

However, when I run the tests at the end of the section, the tutorial says they should pass, but I get the following errors:

FFFF.....*....................................

Here is what's in my authentication_pages_spec.rb file:

require 'spec_helper'

describe "Authentication" do

    subject { page }

    describe "signin page" do
        before { visit signin_path }

        it { should have_content('Sign in') }
        it { should have_title('Sign in') }
    end

    describe "signin" do
        before { visit signin_path }

        describe "with invalid information" do
            before { click_button "Sign in" }

            it { should have_title('Sign in') }
            it { should have_selector('div.alert.alert-error') }

            describe "after visiting another page" do
                before { click_link "Home" }
                it { should_not have_selector('div.alert.alert-error') }
            end
        end

        describe "with valid information" do
            let(:user) { FactoryGirl.create(:user) }
            before do
                fill_in "Email",    with: user.email.upcase
                fill_in "Password", with: user.password
                click_button "Sign in"
            end

            it { should have_title(user.name) }
            it { should have_link('Profile',     href: user_path(user)) }
            it { should have_link('Sign out',    href: signout_path) }
            it { should_not have_link('Sign in', href: signin_path) }
        end
    end
end

[EDIT:] Here is the SessionController file:

class SessionsController < ApplicationController

  def new
  end

  def create
    user = User.find_by(email: params[:session][:email].downcase)
    if user && user.authenticate(params[:session][:password])
      # Sign the user in and redirect to the user's show page.
    else
      flash.now[:error] = 'Invalid email/password combination'
      render 'new'
    end
  end

  def destroy
    sign_out
    redirect_to root_url
  end
end

How can I make the tests to pass?

Thanks.

Without seeing the code for your SessionController class it's a little difficult to tell exactly where you are going wrong. At the end of the tutorial, the create action/method in your SessionController should look like this:

def create
  @user = User.new(user_params)
  if @user.save
    sign_in @user
    flash[:success] = "Welcome to the Sample App!"
    redirect_to @user
  else
    render 'new'
  end
end

In this code if @user saves appropriately, the redirect_to @user portion of the code tells the controller to redirect to @user, or makes a GET request to the user path which, according to the RESTful routes, will return the user/show view. If that fails to save, the controller render's the new view (app/views/sessions/new.html.erb).

Without seeing your controller, I'd suspect you are failing to redirect the controller to another action or render another view (since it's yelling about missing a template for create).

Here's another answer on SO indicating the same.
