Question

我正在通过Michael Hartls RoR教程，这是我第一次使用编码经验。

最近几天，我因为一次失败而失去了一些头发 - 希望你们能帮忙。

Mhartl，第9章 - 清单9.3

捆绑exec rspec spec / requests / user_pages_spec.rb -e“编辑页面”运行选项：包括{：full_description =＆gt; / edit \ page /}

用户控制器

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

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

会话助手

module SessionsHelper

  def sign_in(user)
    cookies.permanent[:remember_token] = user.remember_token
    self.current_user = user
  end

  def signed_in?
    !current_user.nil?
  end

  def current_user=(user)
    @current_user = user
  end

  def current_user
    @current_user ||= User.find_by_remember_token(cookies[:remember_token])
  end

  def sign_out
    self.current_user = nil
    cookies.delete(:remember_token)
  end
end

实用程序

include ApplicationHelper

def valid_signin(user)
  fill_in "Email",    with: user.email
  fill_in "Password", with: user.password
  click_button "Sign in"
end

RSpec::Matchers.define :have_error_message do |message|
  match do |page|
    page.should have_selector('div.alert.alert-error', text: message)
  end
end

Answer 1

重启服务器后故障消失了！

Answer 2

你确定它查询的页面实际上有标题吗？看起来它无法在HTML中找到标题。检查您对该页面的查看，您应该在某处设置标题。 Rspec失败似乎在DOM中找不到title，而是返回nil。

Answer 3

尝试添加：

<% provide(:title, "Edit user") %>

到app / views / users / edit.html.erb文件的顶部。

Answer 4

此外，如果您正在使用它进行测试，请确保重新启动 Spork 。我遇到了同样的问题。
