我正在尝试解决 Michael Hartl 书籍 Rails v 4.0 第 9.6 章的问题 6。
尽管在 rspec 测试中一切看起来都很好：
describe "should redirect a logged in user to root url if user tries to hit new in users controller" do
let(:user) {FactoryGirl.create(:user)}
before do
sign_in user
get new_user_path
end
specify{expect(response).to redirect_to(root_url)}
end
describe "should redirect a logged in user to root url if user tries to hit create in users controller" do
let(:params) do {user: {name: "Tester", email: "test@example.com", password: "password",
password_confirmation: "password"}}
end
let(:user) {FactoryGirl.create(:user)}
before do
sign_in user
post users_path, params
end
specify{expect(response).to redirect_to(root_url)}
end
这是我的控制器片段：
class UsersController < ApplicationController
before_action :is_signed_in, only: [:new, :create]
def new
@user = User.new
end
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
private
def is_signed_in
redirect_to(root_url) if signed_in?
end
end
utility.rb 中的 sign_in 方法
def sign_in(user, options = {})
if options[:no_capybara]
# Signin when not using capybara
remember_token = User.new_remember_token
cookies[:remember_token] = remember_token
user.update_attribute(:remember_token, User.encrypt(remember_token))
else
visit signin_path
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign In"
end
end
但是我的测试用例因以下错误而失败：
Failures:
1) Authentication signin with valid information should redirect a logged in user to root url if user tries to hit create in users controller
Failure/Error: specify{expect(response).to redirect_to(root_url)}
Expected response to be a redirect to <http://www.example.com/> but was a redirect to <http://www.example.com/users/2>.
Expected "http://www.example.com/" to be === "http://www.example.com/users/2".

我试图调试，但无法找出确切的问题。谁可以帮我这个事 ？
编辑：1：添加 route.rb Routes.rb
SampleApp::Application.routes.draw do
resources :users
resources :sessions, only: [:new, :create, :destroy]
root "static_pages#home"
match '/help', to: "static_pages#help", via: 'get'
match '/about', to: "static_pages#about", via: 'get'
match '/contact', to: "static_pages#contact", via: 'get'
match '/signup', to: "users#new", via: 'get'
match '/signin', to: "sessions#new", via: 'get'
match '/signout', to: "sessions#destroy", via: 'delete'
end
编辑 2 我正在用水豚测试它。
