Hartl Ruby on Rails教程4 ch 10，用户编辑测试失败

我正在尝试使用Hartl的教程创建一个自定义网站，从而练习Ruby on Rails。 到目前为止，情况一直很顺利，但我在用户编辑测试“使用友好转发成功编辑”中收到错误，其中用户在登录后未被重定向回编辑页面。这是我收到的错误消息：

FAIL["test_successful_edit_with_friendly_forwarding", UsersEditTest, 3.1409137547016144] test_successful_edit_with_friendly_forwarding#UsersEditTest (3.14s) Expected response to be a redirect to  but was a redirect to . Expected "http://www.example.com/users/787258272/edit" to be === "http://www.example.com/users/787258272". test/integration/users_edit_test.rb:23:in `block in ' 

我觉得这个解决方案非常简单，我错过了，但我似乎无法弄清楚它是什么。

这是我的users_controller：

 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]) end def new @user = User.new end def create @user = User.new(user_params) if @user.save log_in @user flash[:success] = "Account created, welcome to Amplifire Energetics!" redirect_to @user else render 'new' end end def edit end def update if @user.update_attributes(user_params) 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 unless logged_in? flash[:danger] = "Please log in." redirect_to login_url end end # Confirms the correct user. def correct_user @user = User.find(params[:id]) redirect_to(root_url) unless current_user?(@user) end end 

这是我的sessions_controller：

 class SessionsController < ApplicationController def new end def create # Finds user in databse by email @user = User.find_by(email: params[:session][:email].downcase) # Authenticates user based on password if @user && @user.authenticate(params[:session][:password]) log_in @user params[:session][:remember_me] == '1' ? remember(@user) : forget(@user) redirect_back_or @user else flash.now[:danger] = "Invalid email/password combination" render 'new' end end def destroy log_out if logged_in? redirect_to root_url end end 

这是我的sessions_helper

 module SessionsHelper # Logs in user def log_in(user) session[:user_id] = user.id end # Remebers user in persistent session def remember(user) user.remember cookies.permanent.signed[:user_id] = user.id cookies.permanent[:remember_token] = user.remember_token end # Returns true if the given user is the current user. def current_user?(user) user == current_user end # Returns current logged in user def current_user if (user_id = session[:user_id]) @current_user ||= User.find_by(id: session[: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 # Returns true if user logged in def logged_in? !current_user.nil? end # Logs out user def log_out session.delete(:user_id) @current_user = nil end # Forgets a persistent session def forget(user) user.forget cookies.delete(:user_id) cookies.delete(:remember_token) end # Logs out current user def log_out forget(current_user) session.delete(:user_id) @current_user = nil end # Redirects to stored location (or to the default). def redirect_back_or(default) redirect_to(session[:forwarding_url] || default) session.delete(:forwarding_url) end # Stores the URL trying to be accessed. def store_location session[:forwarding_url] = request.original_url if request.get? end end 

这是我的路线文件：

 Rails.application.routes.draw do get 'sessions/new' get 'users/new' root 'static_pages#home' get '/help', to: 'static_pages#help' get '/about', to: 'static_pages#about' get '/contact', to: 'static_pages#contact' get '/signup', to: 'users#new' post '/signup', to: 'users#create' get '/login', to: 'sessions#new' post '/login', to: 'sessions#create' delete '/logout', to: 'sessions#destroy' resources :users end 

这是我的users.yml文件：

 example: name: Lil Wayne email: [e-mail] password_digest:  admin: true archer: name: Sterling Archer email: [e-mail] password_digest:  admin: false 

这是我的用户模型文件：

 class User < ApplicationRecord attr_accessor :remember_token before_save :downcase_email validates :name, presence: true, length: { maximum: 50 } EMAIL_REGEX = /\A([\w+\-].?)+@[az\d\-]+(\.[az]+)*\.[az]+\z/i validates :email, presence: true, length: { maximum: 245 }, format: { with: EMAIL_REGEX }, uniqueness: { case_sensitive: false } has_secure_password validates :password, presence: true, length: { minimum: 6 }, allow_nil: true class << self # Returns hash digest of given string def digest(s) cost = ActiveModel::SecurePassword.min_cost ? BCrypt::Engine::MIN_COST : BCrypt::Engine.cost BCrypt::Password.create(s, cost: cost) end # Returns random token def new_token SecureRandom.urlsafe_base64 end end # Remembers user in database for persistent sessions def remember self.remember_token = User.new_token update_attribute(:remember_digest, User.digest(remember_token)) end def authenticated?(remember_token) return false if remember_digest.nil? BCrypt::Password.new(remember_digest).is_password?(remember_token) end # Forgets a user def forget update_attribute(:remember_digest, nil) end private def downcase_email self.email = email.downcase end end 

这是我的users_edit_test：

 require 'test_helper' class UsersEditTest < ActionDispatch::IntegrationTest def setup @user = users(:example) end test "unsuccessful edit" do log_in_as(@user) get edit_user_path(@user) assert_template 'users/edit' patch user_path(@user), params: { user: { name: "", email: "foo@invalid", password: "foo", password_confirmation: "bar" } } assert_template 'users/edit' end test "successful edit with friendly forwarding" do get edit_user_path(@user) log_in_as(@user) assert_redirected_to edit_user_path(@user) name = "Foo Bar" email = "[e-mail]" patch user_path(@user), params: { 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 end

我发现了我的问题，我忘了将store_location方法添加到users_controller中的logged_in_user方法。
