RailsTutorial: NoMethodError 'permanent' Rake::Test::CookieJar

问题描述

app/helpers/sessions_helper.rb

app/helpers/sessions_helper.rb

module SessionsHelper
  def sign_in(user)
    cookies.permanent[:remember_token] = user.remember_token
    self.current_user = user
  end
  def sign_out
    self.current_user = nil
    cookies.delete(:remember_token)
   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
end

9.2.1 要求登录用户 部分中定义的测试失败:-起初我找不到 sign_in 方法然后我添加了

Tests defined in section 9.2.1 Requiring signed-in users are failing:-At first I was getting sign_in method not found then I added

include SessionsHelper

在 spec/utilities.rb 文件之后，我开始遇到以下错误，说 Rake::Test::CookieJar 中不存在名称为 permanent 的方法.

in spec/utilities.rb file after that I started getting below error, saying no method with name permanent exists in Rake::Test::CookieJar.

是不是因为某些 Gem 版本问题.

Is it due to some Gem version issue.

1) User Pages edit page
 Failure/Error: before { sign_in user}
 NoMethodError:
   undefined method `permanent' for #<Rack::Test::CookieJar:0x007ff12c661e88>
 # ./app/helpers/sessions_helper.rb:3:in `sign_in'
 # ./spec/requests/user_pages_spec.rb:55:in `block (3 levels) in <top (required)>'

推荐答案

刚遇到同样的问题并修复了.

Just ran into the same problem and got it fixed.

似乎他们指的不是 sessions_helper.rb 中的 sign_in 方法，而是 spec/support 中的 sign_in 方法/utilities.rb

It seems they are not referring to the sign_in method in sessions_helper.rb but the the sign_in method in spec/support/utilities.rb

在我的例子中，utilities.rb 中的这个辅助方法有一个不同的名字，重命名后一切正常:-)

In my case this helper method in utilities.rb had a different name, after renaming it everything worked fine :-)
