我遵循 [Michael Hartl's tutorial][1] 并做了第 7 章中的练习，现在有 4 个错误我无法弄清楚如何为我的生活修复。当我手动测试生产应用程序时，根本不存在错误。所以我不知道我的文本开发是否有问题或其他什么，但我完全不知所措，所以我想我会在这里发帖，看看我的菜鸟是否让我失明......谢谢你的帮助！
这是我收到的 4 条错误消息：

这是我的 user_pages_spec.rb 上的代码：
require 'spec_helper'
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
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
describe "after submission" do
before { click_button submit }
it { should have_selector('title', text: "Sign up") }
it { should have_content('error') }
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
describe "after saving the user" do
before { click_button submit }
let(:user) { User.find_by_email('user@example.com') }
it { should have_selector('title', text: user.name) }
it { should have_selector('div.alert.alert-success', text: 'Welcome') }
end
end

这是views/users/show.html.erb的模板代码
<% provide(:title, @user.name) %>
<div class="row">
<aside class="span4">
<section>
<h1>
<%= gravatar_for @user %>
<%= @user.name %>
</h1>
</section>
</aside>
</div>
然后是 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
sign_in @user
flash[:success] = "Welcome to the Sample App!"
redirect_to @user
else
render 'new'
end
end
end
