在测试 ruby​​-on-rails 教程的注册页面时出现以下错误：

Failures:

1) User pages signup with valid information should create a user
 Failure/Error: expect { click_button submit }.to change(User, :count).by(1)
 ActionView::MissingTemplate:

Failed examples:

rspec ./spec/requests/user_pages_spec.rb:42 # User pages signup with valid information should create a user

我不确定问题出在哪里，我已经多次检查代码以确保它与书中的示例匹配。我很确定它与 new.html.erb 文件有关

user_pages_spec.rb

require 'spec_helper'

describe "User pages" do
  subject { page }

  describe "signup page" do
    before { visit signup_path }

    it { should have_selector('h1',    text: 'Sign up') }
    it { should have_selector('title', text: full_title('Sign up')) }
  end

  describe "profile page" do
    let(:user) { FactoryGirl.create(:user) }
    before { visit user_path(user) }

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

  describe "signup" do

    before { visit signup_path }

    let(:submit) { "Create my account" }

    describe "with invalid information" do
      it "should not create a user" do
        expect { click_button submit }.not_to change(User, :count)
      end
    end

    describe "with valid information" do
      before do
        fill_in "Name",         with: "Example User"
        fill_in "Email",        with: "user@example.com"
        fill_in "Password",     with: "foobar"
        fill_in "Confirmation", with: "foobar"
      end

      it "should create a user" do
        expect { click_button submit }.to change(User, :count).by(1)
      end
    end
  end
end

新的.html.erb

<%= provide(:title, 'Sign up') %>
<h1>Sign up</h1>

<div class="row">
  <div class="span6 offset3">
    <%= form_for(@user) do |f| %>

      <%= f.label :name %>
      <%= f.text_field :name %>

      <%= f.label :email %>
      <%= f.text_field :email %>

      <%= f.label :password %>
      <%= f.password_field :password %>

      <%= f.label :password_confirmation, "Confirmation" %>
      <%= f.password_field :password_confirmation %>

      <%= f.submit "Create my account", class: "btn btn-large btn-primary" %>
    <% end %>
  </div>
</div>

users_controller.rb

class UsersController < ApplicationController

  def show
    @user = User.find(params[:id])
  end

  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:user])
    if @user.save
      # Handle a successful save.
    else
      render 'new'
    end
  end
end

简短的回答：

它不应该工作（还）。继续教程，答案将在第 7.4 节；

稍微长一点 回复：

当您填写表单并按下提交按钮时，会触发 users_controller 中的创建事件。由于您（还）没有任何代码，Rails 假设您只想渲染create.html.erb，它不存在（并且永远不会存在）。为了让它立即工作，你必须在redirect_to @user下面添加if @user.save. 检查清单 7.25；

跳到教程底部，问题得到解答。redirect_to @user在您的#Handle 下包含成功保存。
