我有三个资源-users和。我只是嵌套在下面并相应地更新了我的链接，但是我从 rspec 收到两个错误，这对我来说完全是个谜。在我嵌套路线之前一切正常。listsitemslistsusers

我是 Rails 的新手，非常感谢任何帮助！

  1) Authentication authorization for non-signed-in users in the Lists controller submitting to the destroy action 
     Failure/Error: before { delete user_list_path(user, FactoryGirl.create(:list)) }
     ActiveRecord::RecordInvalid:
       Validation failed: Email has already been taken
     # ./spec/requests/authentication_pages_spec.rb:84:in `block (6 levels) in <top (required)>'

  2) User pages profile page 
     Failure/Error: before { visit user_path(user) }
     ActionView::Template::Error:
       No route matches {:action=>"show", :controller=>"users", :id=>nil}

路线.rb

MyApp::Application.routes.draw do
  resources :users do
    resources :lists, only: [:show, :create, :destroy]
  end
  resources :items, only: [:show, :create, :destroy]
  resources :sessions, only: [:new, :create, :destroy]

用户.rb

class User < ActiveRecord::Base
  attr_accessible :name, :email, :password, :password_confirmation
  has_secure_password
  has_many :lists, dependent: :destroy
  has_many :items, through: :lists

列表.rb

class List < ActiveRecord::Base
  attr_accessible :name
  belongs_to :user
  has_many :items, dependent: :destroy

项目.rb

class Item < ActiveRecord::Base
  attr_accessible :link, :list_id, :title
  belongs_to :list

更新

user_pages_spec.rb

require 'spec_helper'

describe "User pages" do

  subject { page }

  describe "profile page" do
    let(:user) { FactoryGirl.create(:user) }
    let!(:l1) { FactoryGirl.create(:list, user: user, name: "Foo") }
    let!(:l2) { FactoryGirl.create(:list, user: user, name: "Bar") }

    before { visit user_path(user) }

    it { should have_selector('h1',    text: user.name) }
    it { should have_selector('title', text: user.name) }

    describe "lists" do
      it { should have_content(l1.name) }
      it { should have_content(l2.name) }
      it { should have_content(user.lists.count) }
    end
  end

  describe "lists page" do
    let(:user) { FactoryGirl.create(:user) }
    let!(:l1) { FactoryGirl.create(:list, user: user, name: "Foo") }
    let!(:i1) { FactoryGirl.create(:item, list: l1, title: "Shirt") }

    before { visit user_list_path(user, l1) }

    it { should have_content(i1.title) }
    it { should have_content(l1.items.count) }
  end
...

更新 2

users_controller.rb

class UsersController < ApplicationController
  before_filter :signed_in_user, only: [:edit, :update]
  before_filter :correct_user,   only: [:edit, :update]

  def show
    @user = User.find(params[:id])
    @lists = @user.lists
    @list = current_user.lists.build if signed_in?
  end

  def new
    @user = User.new
  end

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

  def edit
  end

  def update
    if @user.update_attributes(params[:user])
      flash[:success] = "Profile updated"
      sign_in @user
      redirect_to @user
    else
      render 'edit'
    end
  end

  private

    def correct_user
      @user = User.find(params[:id])
      redirect_to(root_path) unless current_user?(@user)
    end

您的第一个错误是告诉您您正在创建的用户无效，因为已经创建了具有该电子邮件的用户。（未能通过电子邮件唯一性验证）您可以通过更改用户工厂以对电子邮件进行排序来解决此问题，以便每条记录都是唯一的，如下所示：

sequence(:email) { |n| "User#{n}@example.com"}

由于完全相同的原因，第二次测试失败了。由于您的用户记录为零，因此您实际上是在尝试从数据库中获取不存在的记录。它告诉你这一行：

No route matches {:action=>"show", :controller=>"users", :id=>nil}

通过让 user = nil，您的 show 操作中会发生以下情况：

your implementation will look something like this:
#####
@user = User.find(params[:id])
#####

因为 params[:id] = nil，你得到

User.find(nil)

这将失败，因为没有 id 为 nil 的用户记录。您的其余实施应该没问题。
