Question

I am on chapter 9 and it seems that the tests are failing once again. Here is the relevant code:
sessions_helper.rb:
module SessionsHelper
#logs in the given user
def log_in(user)
session[:user_id] = user.id
end
#Remember a user in a persistent session
def remember(user)
user.remember
cookies.permanent.signed[:user_id] = user.id
cookies.permanent[:remember_token] = user.remember_token
end
def current_user?
user == current_user
end
def current_user
if (user_id = session[:user_id])
#current_user ||= User.find_by(id: user_id)
elsif (user_id = cookies.signed[:user_id])
user = User.find_by(id: user_id)
if user && user.authenticated?(cookies[:remember_token])
log_in user
#current_user = user
end
end
end
def logged_in?
!current_user.nil?
end
#Forgets a persistent session
def forget(user)
user.forget
cookies.delete(:user_id)
cookies.delete(:remember_token)
end
def log_out
forget(current_user)
session.delete(:user_id)
#current_user = nil
end
end
Here is users_edit_test.rb:
require 'test_helper'
class UsersEditTest < ActionDispatch::IntegrationTest
# test "the truth" do
# assert true
# end
def setup
#user = users(:michael)
end
test "successful edit" do
log_in_as(#user)
get edit_user_path(#user)
assert_template 'users/edit'
name = "Foo Bar"
email = "foo#bar.com"
patch user_path(#user), user: { name: name,
email: email,
password: "",
password_confirmation: ""}
assert_not flash.empty?
assert_redirected_to #user
#user.reload
assert_equal name, #user.name
assert_equal email, #user.email
end
test "unsuccessful edit" do
log_in_as(#user)
get edit_user_path(#user)
assert_template 'users/edit'
patch user_path(#user), user: { name: "",
email: "foo#invalid",
password: "foo",
password_confirmation: "bar"}
assert_template 'users/edit'
end
end
Here is users_controller.rb:
class UsersController < ApplicationController
before_action :logged_in_user, only: [:edit, :update]
before_action :correct_user, only: [:edit, :update]
def show
#user = User.find(params[:id])
# debugger
end
def new
#user = User.new
end
def create
#user = User.new(user_params)
if #user.save
#Handle a successful save
log_in #user
flash[:success] = "Welcome to the Sample App!"
redirect_to #user
else
render 'new'
end
end
def edit
#user = User.find(params[:id])
end
def update
#user = User.find(params[:id])
if #user.update_attributes(user_params)
#Handle a successful update.
flash[:success] = "Profile updated"
redirect_to #user
else
render 'edit'
end
end
private
def user_params
params.require(:user).permit(:name, :email, :password, :password_confirmation)
end
#Before filters
# Confirms a logged-in user
def logged_in_user
flash[:danger] = "Please login to access this page."
redirect_to login_url
end
def correct_user
#user - User.find(params[:id])
redirect_to(root_url) unless #user == current_user
end
end
And lastly here are the errors:
1) Failure:
UsersEditTest#test_unsuccessful_edit [/home/robert/sample_app/test/integration/users_edit_test.rb:32]:
expecting <"users/edit"> but rendering with <[]>
2) Failure:
UsersEditTest#test_successful_edit [/home/robert/sample_app/test/integration/users_edit_test.rb:15]:
expecting <"users/edit"> but rendering with <[]>
3) Failure:
UsersControllerTest#test_should_redirect_update_when_logged_in_as_wrong_user [/home/robert/sample_app/test/controllers/users_controller_test.rb:37]:
Failed assertion, no message given.
4) Failure:
UsersControllerTest#test_should_redirect_edit_when_logged_in_as_wrong_user [/home/robert/sample_app/test/controllers/users_controller_test.rb:30]:
Failed assertion, no message given.
This is annoying cause I don't see anything different from the book and the code that I have (in most parts copied and pasted from the book). In the book it apparently works, but when I run the test I get these four failures.

Answer 1

I see, you have a typo in your code.
In your users_controller.rb's correct_user method, you have: #user - User.find(params[:id]), which should be: #user = User.find(params[:id]).
Change that to:
def correct_user
#user = User.find(params[:id])
redirect_to(root_url) unless #user == current_user
end
See if that fixes your issue.
If not, try adding these two methods to your SessionsHelper module.
If that also does not fix your issue. I would suggest you to clone the original working repo from github and try to figure out what you have missed in your version. I have cloned this github repo and all the tests are passing.
