Michael Hartl教程3.2 - 第9章 - 错误消息和编辑/更新页面问题

Question

我正在研究Michael Hartl Rails 3.2，我已经坚持了几个小时这些问题。我无法弄清楚我错过了什么，因为我已经完成了7,8,9中的所有代码，以确保它是准确的。更新/编辑页面一直有效，直到我添加到用户控件的私有部分。

由于我添加了这些内容，当我手动测试页面并点击设置时，它会直接进入登录页面。除非signed_in，它似乎没有取消？并从用户控制器页面将其重定向到签名页面。我的测试失败是有道理的，因为编辑页面没有登录。任何想法或建议都将非常感激。如果您需要查看其他页面，请告诉我们。

错误消息 - 我得到9个错误，如下所示

如果遇到此问题 - 请确保在application_controller中没有此问题。这是一个非常小的错误，给我带来了各种各样的悲伤。再次 - 请勿使用此代码......

 include SessionsHelper

 private
def current_user
    @current_user ||= User.find(session[:user_id]) if session[:user_id]

Answer 1

Capybara找不到电子邮件地址。

在填写登录表单之前，您应该继续操作。改变你的功能：

def sign_in(user)
  visit signin_path
  fill_in "Email", with: user.email
  fill_in "Password", with: user.password
  click_button "Sign in"
  # Sign in when not using Capybara as well.
  cookies[:remember_token] = user.remember_token
end

我认为你的表格形式正确。您可以在visit signin_path之后添加puts page.html以查看html，如果安装了launchy，则可以添加save_and_open_page。
